Vehicles equipped with Stop/Start have two batteries, a cranking battery (large battery) and an accessory battery (small battery). Both batteries are charged together when the Power Control Relay (PCR) is closed. Once the vehicle is running and the Stop/Start event takes place the PCR relay open the connection and isolated the accessories from the cranking battery so that there is no voltage interruption to the vehicle.
WhenI was a very active EMT and Fire Police and Amatuer radio op, I used a similar type isolation. My radios linear Amp and flashy lights were isolated from the vehicle main battery. I used 2 deep cycle marine batteries which would last 16 or more hours. The car would still start although you could hear the a0lternator pull the engine down.
I had a BMW with dual batteries, and the Mercedes I currently drive has dual batteries. For those vehicles, I think the purpose was so that all of the power accessories like alarms, cameras that are powered all the time, as well as audio equipment, etc, wouldn't eat up the main battery.
Weird, me '21 rav4 with start/stop only has 1 battery, an "enhanced flooded lead acid battery (EFB)". I think I remember reading that AGM's are an acceptable substitute for an EFB too.

What happened to a battery hold down, negative and positive terminals, 10 minutes and be done. 😢😢😢 NOT all new technologies are for the best. Had a new "super battery" put in my 17 Silverado a couple of years ago at a "battery shop" here in town. Damn thing must have weighed 50lbs, no kidding. Started having warnings ans messages on my screen I'd never seen before. Ended up going to a dealership. They "supposedly" found close to 150 codes, if that's even possible stored. 3 hrs later (was only charged 1 hr labor) it was all due to "loose" connections. Goes to show even a battery takes a degree to change nowadays 😢😢😢😢
Not lame at all... What I learned this time is "Don't buy anything that you can't see the battery... Don't let your friends buy anything that has more than one battery!" ;) All my stuff is very old, and even an old coot like me can still change the battery in about 4 minutes.
You should see where the battery is buried on my Kawasaki W800. Not too bad really but it is buried under the ECM. Very hard to get charger leads hooked up. I need to put a set of permanent lead and connector.
Chrysler dealer tech here, Eric you made it a little more difficult than you needed to. My process when I have to replace those batteries is this- First, I take the coolant reservoir out and move it to the side. Then I disconnect the battery cables. The hold down for the little battery, you don't need to remove the relay assembly, just take the nut off the hold down and flip the whole thing out of the way. I have no idea why there is that little clip with the philip screws, it's just annoying. The big battery hold down is easy enough. Before I put the new batteries in, I test them to be sure that they're good, saves me from having to take everything back apart after finding out that one or both new batteries are bad, got burned on that once, won't ever repeat that again. Then I install them. I leave that red cover and the coolant reservoir off til after I've started the vehicle and verified that both batteries have charging voltage. Once I'm done with the verification of the charging voltage to both batteries, i then install the cover and the reservoir. The reason I check at both batteries for charging voltage is that there are fuses that feed the charging voltage to the batteries, and sometimes, when people jumpstart the vehicles, they accidently blow one of the fuses, causing one battery to not get charged. The current Grand Cherokee and Wagoneer/Grand Wagoneer have a 150 amp fuse that is very sensitive, and I've had to change many due to them being blown and not feeding one of the batteries charging voltage, causing issues.
The screws stop the fuse tray moving around and loosening the positive terminal clamp, useful if it has been over tightened, and also useful to prevent over tightening as there's no torque on the clamp so they don't need the 200lb gorilla leaning on the 10 millimeter

We get to learn from that via your videos. I'd happily listen to you in the background while I do something else, tuning in when I hear something interesting if you decide go do longer videos, You'd be taking on BBC Radio 4, an institution in the UK that I would happily replace with lengthy videos by yourself. Keep Calm and Carry on. God's speed to you!
Just keep em coming. It feels like I am hanging out in the shop I worked in a lifetime ago when I left the profession for several reasons. I miss those days and hanging here is a great trip down memory road. Not to mention that I'm still not too old to learn a few new tricks for the 'fleet' that I still take care of.
I want to thank you for showing us what new over engineered cars are all about. Their numerous flaws and short comings so that we can make an informed choice of what we don't want in a vehicle. These videos are real treasures for buyers. And if the car companies are watching they should be taking notes for future designs. There is a movement going on right now that buyers all over the world are fed up with this nonsense. That is why car sales are going downhill fast. Thank you Eric. Knowledge is power. The power to change what is wrong.
Plus no need to remove half the engine to enable the battery to be easily extracted and get the new one back in. I couldn't believe all the crap that Eric had to disconnect to get the battery out.
Eric, I watch whatever the hell you post. You are part of why I've learned more about being a mechanic. Even learned a couple tricks from your vids. Always love watching the content you post.
@DavidD-qr2vn Yup, have to disagree. Spent 18 years as an industrial maintenance technician and 22 years as an Avionics Technician. Troubleshooting was my thing. Mechanical, electrical, hydraulic, pneumatic and electronics. Above average humbly. Engineering made the maintenance so much more difficult than necessary. In my fields anyway.
Ha ha ha, loved the intro and video description. With all the fake drama and hyperbole in RUclips titles and clickbait headlines, your refreshing honesty is genuine gold.
That is the most painful battery change (almost)I have ever watched done. I applaud your expertise. The worst I had was a Piper Aircraft twin engine plane that I swear they suspended the battery hanging from a wire up to the ceiling and proceeded to bolt, rivet, and weld the fuselage around it. Then they cut the wire.
I live across the street from a Dodge Jeep dealer. When the compass first came out I went and had a look at one and took it for a test drive. It was a disappointing experience to say the least. It reeked of CHEAP. When the salesman opened the hood I took one look and decided I would never own one. Absolutely no room for a mechanic to work on the thing along with a lot of parts like the fuzzy cardboard shown here that would disappear in a few years. You could see that it was a throw away vehicle. Today it appears that almost everything being made is throw away. I will be sticking with my 2016 F150 simply because it's still built like a vehicle should be and there are so many of them that there will be used parts available until I don't need a vehicle anymore. This was not a boring video. It was informative simply because it showed the junk being produced today and how they are making it with no concern for how you will keep it running until it's paid for. The vehicles of yesteryear had an engine bay. The vehicles of today have an engine viewing port..........
Eric. Please wear a proper respirator when you undercoat vehicles. That stuff is very dangerous when breathed in. Any and all undercoating fluids are dangerous. When it gets in your lungs it latches onto the inside lining of your lungs and will build up over time. Once that stuff gets into your lunge it is there for life. You can’t get it out. When your body has reached its limit as we are all different you will eventually drown in your own fluids as your lungs cannot filter out liquids. It happened to a lot of my friends in the undercoating business including my brother in law. He died in his own fluids. It’s a very very painful way to die. We all love you out here and want you to live a long healthy life to make more videos. I’m sure your kids and wife wouldn’t mint it either. Be safe my friend.
With those Chrysler duel battery systems, I've found you need to remove the main battery first then aux battery and install aux battery first then main battery. Also the negative lead on the main battery needs to be the last terminal reconnected otherwise you risk causing a check engine light. Just another example of brilliant engineering.
When I replace my batteries, I hook up a power supply or one of my hobby batteries to the electrical system to prevent issues like this or at least to prevent all the relearns.
That's what they all say. I had no issues before YOU changed my battery And now it has a check engine light 🚨. It's your fault, I want YOU to fix my car. 😅 I have heard that so many times.
@@2nickles647 That model year dose not require a reset, even though the AAA specs say it dose, you go through the trouble to hook up your reset tool only to find that out!

Eric, I just recently went out and bought a brand new 2024 Escalade V. I noticed that they did not put the start stop system on the V. Even though if you get the regular Escalade, it will have the start stop system. The funny thing is when I took it in for service. I brought that to their attention. Five technicians came out and were actually surprised it didn’t have the start stop system. As a matter fact, they looked it up because it baffled them as well. Supposedly, All late model cars are supposed to have that system with the exception of diesel. So we’re not certain why GM chose not to put it on the V. Maybe it simply has to do with the supercharger. I just thought I would share this with you. Maybe there’s somebody out there that works for General Motors that can explain their reasoning. Don’t get me wrong. I’m glad it doesn’t because I hate that system, lol my thoughts Ron
Eric I worked as a mechanic for sixty years I thought we had it bad from what I see you guys are saints that have to work on these vehicles. Love your videos 👍
You are The Man, Eric. Not only have I've watched anything since 2015, I've watched everything. Thanks for keeping this old man entertained for so many years.
Nice job, Eric O. Not boring at all. Real life. She was lucky to get five years. Had a 2015 Cherokee that burned through batteries around the 3 year time frame. Jeep has a similar set-up in Wrangler however the little battery is stuffed way down under main battery. Either have to remove a few items up top or pull right front tire and access through wheel well. Nice engineering.
As someone who works in a battery workshop here in Australia, some manufacturers are a real challenge to change out the batteries. They give you zero room to move, sit everything possible on top of the battery, and some vehicles inbed the battery so deep in the engine bay you have to remove the wiper cowling, wipers etc. It's a real piss pot when we don't have specialised tools either. Just makes our life a bit more challenging 😂.
On your dropped nut.....A little trick I used to use if you can't get your hands in there and the stud has an unthreaded tip, I'd take a long screwdriver and slide the nut up to the handle, place the tip of the screwdriver on the stud and let the nut go.
Just for your knowledge, and your experience that we learn so much from..YES, WE WOULD. That just shows how much of an influence you have in so many of our lives, and our learning of things other than politics. Thanks, Eric O. I've learned a lot from watching you and Rainman Ray. And, I imagine all of the followers have, and shared, too. We also love to see and hear the interaction you have with Mrs O. It's like watching our family members who actually LIKE or LOVE each other, not like those Thanksgiving and Christmas family we have to deal with...LOL. Cheers.
Eric. you may think this was a simple video but to be honest i know of lot of people that has the stop and start system on their vehicles and they have no idea there are two batteries. so this video does a lot of good and as always you did a great job in showing how to change them.
.....and if you don't connect the B+ wire position according to GM and torque to specs...you'll have a 'little' fire under the intake manifold. No bueno.
@70 I remember the hardest thing about changing a battery was lifting it. It's only lame if you do it all the time. Your videos are valuable Eric because you find stuff wrong with cars in the rust belt way before we in the south do. Think of it like you are a news network and have breaking news all the time. lol
My Acadia took me back to my 49 Chevy pickup with a battery box in the floorboard, except the GM engineers decided to size the box to a few millimeters larger than the battery case and hide it in the floor behind the front passenger seat. First battery changeout I was lucky I could dead lift it out using my index fingers.
I have ia 2002 Lesabre with battery under back seat. Don't really mind,. one place is as good as another. Besides there is not much residual room under the hood of a 3800 engine.
Eric, I come to watch you wrenching. Yeah the interesting problems are cool, or the trips to the scrap-yard, but it doesn't matter... Just anything you want to put on Camera works for me! Oh and a healthy dose of Mrs. O, Luna and the dogs... Always a treat to see the whole family!

Go to the nearby parts store for a diagnostic. They can Diagnostic your vehicle free of charge and sell you the part you need in a jiffy. The 20 year old kid is a qualified technician. He can swing the diagnostic tool with the pro's.
Had to go back and check because I didn't see you tighten the positive terminal om the main battery but upon review I saw that you did. Good job. Love the varied subjects of your videos. Very helpful for the DIY guys.
Looks like they purposely made the batteries a bit of a pita to get to and a bit intimidating for the average joe to change himself. I could be wrong of course, but I wouldn't put it past some automakers to do that.
Videos like this make me enjoy the fact that my trucks are a 1992 and a 1978. Both are my daily drivers depending on my day. The reason for the red tab thingy, Is to keep from putting twist force on the post when changing fuses.
@@rogerdedrick373The batteries on these start-stop systems can last for 3 years and depending on situations and circumstances. This summer has killed alot of them.
On another note. Regarding the start Stop system. Although they claim the reason why they’re installing them is for fuel efficiency. Truth is it doesn’t save much fuel. If anything as the vehicle gets older, just like any other vehicle and starts to become a hard to start. I would think the start stop would become a liability. Another words if you’re driving along and you happen to come to a set of train tracks. The vehicle shuts off and then when you need to go, it struggles to restart because of either poor maintenance or simply wore out. Not to mention, the amount of wear and tear on the starter and the battery system. Just my thoughts.Ron
Nope, it's the people who ignore the maintenance on their vehicles. It brakes down on the train tracks. So they blame someone else or anything because they refuse to get it maintenance because it cost to much.
Actually this is a real issue. My neighbor's Audi experienced just that - stopped at a light last winter and wouldn't restart. Expensive flat bed ride to mechanic later it was operational once again.
Most modern vehicles aren't using the starter for the stop/start feature, they use the alternator/generator to restart. You'd be surprised how much time adds up. Hours a year of idling saved, you do that across millions of cars and that's a lot of emissions saved.
I was in our little town and a car won't start at a light. The amount of gas that was saved by car would not offset the expense of getting car towed and 2nd battery. You can save a good bit of gas with driving habits, tire pressure and maintenance
I’m not a fan of the auto stop start because it feels like my vehicle has a tiny period of time where the car is unresponsive between the stop and the start. That non response is very discernible between my taking my foot off the brake and pressing the accelerator pedal. In city driving, merging from a stop into traffic, it’s enough to make me feel just a little uneasy.
Somebody please explain the advantages of these dual battery systems. I took a quick look online and of course I have two pages of AI bullshit.

@SouthMainAuto could you please do a video on scanners? I work for a municipality on police cars and i can purchase a scanner. I just don't want to make the wrong purchase and find out the hard way there something it can't do.
Love the channel, thanks !
That is why I am glad I drive a 1992 Buick Roadmaster Estate Wagon. Easy in, easy out.
It's a classic!!
The one with the vinyl siding.
The OG of vinyl wraps.
That sentence hasn't been said since 1992
And with a Corvette engine
I said anything. And yes I learned something new.
I'm an engineer and I love your videos and this one was no different. Watching you work is always educational. Your knowledge and experience is something gathered over time and has intrinsic value. We get to learn from that via your videos. I'd happily listen to you in the background while I do something else, tuning in when I hear something interesting if you decide go do longer videos, You'd be taking on BBC Radio 4, an institution in the UK that I would happily replace with lengthy videos by yourself. Keep Calm and Carry on. God's speed to you!
Eric, I would watch a video of the grass growing at your shop. Oh wait, the guy with the mower is coming.
😂
😂😂😂😂
Just keep em coming. It feels like I am hanging out in the shop I worked in a lifetime ago when I left the profession for several reasons. I miss those days and hanging here is a great trip down memory road. Not to mention that I'm still not too old to learn a few new tricks for the 'fleet' that I still take care of.
I want to thank you for showing us what new over engineered cars are all about. Their numerous flaws and short comings so that we can make an informed choice of what we don't want in a vehicle. These videos are real treasures for buyers. And if the car companies are watching they should be taking notes for future designs. There is a movement going on right now that buyers all over the world are fed up with this nonsense. That is why car sales are going downhill fast. Thank you Eric. Knowledge is power. The power to change what is wrong.
Remember the days when replacing a battery was just 2 wires!
So true! I am going to hate the day I need to buy a new car. Just too much stuff in these new ones!
Cars are going to be subscriptions
Plus no need to remove half the engine to enable the battery to be easily extracted and get the new one back in. I couldn't believe all the crap that Eric had to disconnect to get the battery out.
I admire your skills Eric. I , Myself, would rather pour a 100 yard slab through a Hurricane. Amen to you Brother!!
Eric, I watch whatever the hell you post. You are part of why I've learned more about being a mechanic. Even learned a couple tricks from your vids. Always love watching the content you post.
I think we would all watch you read the NYC phone book. Best channel on YT.
Eric, I have to say that an informal video of yours is still way better than most folks' serious ones.
Yup, we are all learning together about maintenance, and at the same time having a healthy hate for engineers. Good job.
Engineers aren't the problem, bean counters are.
@@DavidD-qr2vn In this case it is the gumum (pronounced gum um, i.e.government) up with their CAFE stuff. Now they adding nanny state stuff.
@@johncooper4637I believe start stop is pollution gumgum not cafe read it somewhere.
@DavidD-qr2vn Yup, have to disagree. Spent 18 years as an industrial maintenance technician and 22 years as an Avionics Technician. Troubleshooting was my thing. Mechanical, electrical, hydraulic, pneumatic and electronics. Above average humbly. Engineering made the maintenance so much more difficult than necessary. In my fields anyway.
again this is the best subscription I have. much love ❣
Ha ha ha, loved the intro and video description. With all the fake drama and hyperbole in RUclips titles and clickbait headlines, your refreshing honesty is genuine gold.
The next time you paint a room bring us along so we can watch the paint dry. I am sure it will be great.
It's ridiculous how complicated they make the "easy stuff!" J.U.N.K.
That is the most painful battery change (almost)I have ever watched done. I applaud your expertise.
The worst I had was a Piper Aircraft twin engine plane that I swear they suspended the battery hanging from a wire up to the ceiling and proceeded to bolt, rivet, and weld the fuselage around it. Then they cut the wire.
I live across the street from a Dodge Jeep dealer. When the compass first came out I went and had a look at one and took it for a test drive. It was a disappointing experience to say the least. It reeked of CHEAP. When the salesman opened the hood I took one look and decided I would never own one. Absolutely no room for a mechanic to work on the thing along with a lot of parts like the fuzzy cardboard shown here that would disappear in a few years. You could see that it was a throw away vehicle.
Today it appears that almost everything being made is throw away. I will be sticking with my 2016 F150 simply because it's still built like a vehicle should be and there are so many of them that there will be used parts available until I don't need a vehicle anymore.
This was not a boring video. It was informative simply because it showed the junk being produced today and how they are making it with no concern for how you will keep it running until it's paid for. The vehicles of yesteryear had an engine bay. The vehicles of today have an engine viewing port..........
Eric. Please wear a proper respirator when you undercoat vehicles. That stuff is very dangerous when breathed in. Any and all undercoating fluids are dangerous. When it gets in your lungs it latches onto the inside lining of your lungs and will build up over time. Once that stuff gets into your lunge it is there for life. You can’t get it out. When your body has reached its limit as we are all different you will eventually drown in your own fluids as your lungs cannot filter out liquids.
It happened to a lot of my friends in the undercoating business including my brother in law. He died in his own fluids. It’s a very very painful way to die.
We all love you out here and want you to live a long healthy life to make more videos. I’m sure your kids and wife wouldn’t mint it either.
Be safe my friend.
Yea but on the light side his lungs will never rust !
These kind of videos are probably the most helpful to most because it enables people to do these kind of "simple" jobs themselves.
With those Chrysler duel battery systems, I've found you need to remove the main battery first then aux battery and install aux battery first then main battery. Also the negative lead on the main battery needs to be the last terminal reconnected otherwise you risk causing a check engine light. Just another example of brilliant engineering.
When I replace my batteries, I hook up a power supply or one of my hobby batteries to the electrical system to prevent issues like this or at least to prevent all the relearns.
Looks like Mr. O did exactly that. Main battery neg last one to connect.
You forgot to reset the battery monitor and clear codes.
That's what they all say.
I had no issues before YOU changed my battery And now it has a check engine light 🚨.
It's your fault, I want YOU to fix my car. 😅
I have heard that so many times.
@@2nickles647 That model year dose not require a reset, even though the AAA specs say it dose, you go through the trouble to hook up your reset tool only to find that out!
My wife has a ‘21 Compass and I see this job in my near future. For me this video was absolute GOLD! When I do this PITA job I will be regretting that I sold my ‘76 Caprice Classic.
Will watch all of it. Doesn’t change the fact that jeeps are junk. Especially the compass. 😂😂😂 love your content brother.
A fresh pot of coffee and a South Main Auto video staring Eric O, what better way to start the day!! 👍👍
Eric, I just recently went out and bought a brand new 2024 Escalade V. I noticed that they did not put the start stop system on the V. Even though if you get the regular Escalade, it will have the start stop system. The funny thing is when I took it in for service. I brought that to their attention. Five technicians came out and were actually surprised it didn’t have the start stop system. As a matter fact, they looked it up because it baffled them as well. Supposedly, All late model cars are supposed to have that system with the exception of diesel. So we’re not certain why GM chose not to put it on the V. Maybe it simply has to do with the supercharger. I just thought I would share this with you. Maybe there’s somebody out there that works for General Motors that can explain their reasoning. Don’t get me wrong. I’m glad it doesn’t because I hate that system, lol my thoughts Ron
Sounds like a good time for another “a normal day at the shop” video. Been a long time since one of those. I enjoyed it. Keep up the great work!
Leaving the black plastic cap on the negative of the main battery till the end to see if you forget it was a stroke of RUclips genius.
Eric I worked as a mechanic for sixty years I thought we had it bad from what I see you guys are saints that have to work on these vehicles. Love your videos 👍
It’s always fluid film season, I even put it on my gate hinges
You are The Man, Eric. Not only have I've watched anything since 2015, I've watched everything. Thanks for keeping this old man entertained for so many years.
You're too modest, most of us would watch you change air in a tire, we tune in to watch you and Mrs O.
I just had to change these out in my wife’s car, you saved me a whole bunch of money my guy!
Every time the door bell rings,i laugh and say hey its that guy😂
Nice job, Eric O. Not boring at all. Real life. She was lucky to get five years. Had a 2015 Cherokee that burned through batteries around the 3 year time frame.
Jeep has a similar set-up in Wrangler however the little battery is stuffed way down under main battery. Either have to remove a few items up top or pull right front tire and access through wheel well. Nice engineering.
Geeeze. And we used to complain about GM side-post.
Right 😂
I thought changing the second battery that’s underneath our old shuttle bus was a PITA!
As someone who works in a battery workshop here in Australia, some manufacturers are a real challenge to change out the batteries. They give you zero room to move, sit everything possible on top of the battery, and some vehicles inbed the battery so deep in the engine bay you have to remove the wiper cowling, wipers etc.
It's a real piss pot when we don't have specialised tools either. Just makes our life a bit more challenging 😂.
You're right, we will watch anything.
Speaking of, wouldn't mind a new fluid film/crown video. They're always interesting
Yes Mrs o’s minivan. Get on it Eric. NOW!😅
Tried to watch this in a noisy cafe and realised it your commentary as much as what you are doing that is so engaging❤
I bet the clerks at Autozone get this done with no damage to all those fiddly bits.
Eric, you do not make dumb videos! Even if it's replacing a light bulb, someone might learn something! Thanks for all your time Eric!
Not boring at all. Love your commentary. Hate start/stop systems. I will keep my 2004 CRV and rebuild it as needed.
As a retired mechanic, watching some other poor shlub doing even the most mundane automotive task is like asmr for my soul!
On your dropped nut.....A little trick I used to use if you can't get your hands in there and the stud has an unthreaded tip, I'd take a long screwdriver and slide the nut up to the handle, place the tip of the screwdriver on the stud and let the nut go.
We’re so desperate for a SMA video we’d even watch a brake job.
Just for your knowledge, and your experience that we learn so much from..YES, WE WOULD. That just shows how much of an influence you have in so many of our lives, and our learning of things other than politics. Thanks, Eric O. I've learned a lot from watching you and Rainman Ray. And, I imagine all of the followers have, and shared, too. We also love to see and hear the interaction you have with Mrs O. It's like watching our family members who actually LIKE or LOVE each other, not like those Thanksgiving and Christmas family we have to deal with...LOL. Cheers.
❤ the torque wrench sound affects! 😂😅
South Main Auto.. Any time you break out the ole torque wrench we know it's going to be a great video my friend. Keep them coming Eric.
We need another sma brake job video! It’s been awhile
As a 67 year old OG I think the intro of the top nut battery clamps are one of the best advancements in automotive in many years.
Man...a threefer!!😊 Thanks Eric!
Eric. you may think this was a simple video but to be honest i know of lot of people that has the stop and start system on their vehicles and they have no idea there are two batteries. so this video does a lot of good and as always you did a great job in showing how to change them.
I will definitely watch it all!
You didn’t think we were serious did you Eric ???😉
If you post it I will watch it.
For your next video change a starter on a olds or caddy . You know the one where the starter is UNDER the intake manifold !! Good times .
.....and if you don't connect the B+ wire position according to GM and torque to specs...you'll have a 'little' fire under the intake manifold. No bueno.
@70 I remember the hardest thing about changing a battery was lifting it. It's only lame if you do it all the time. Your videos are valuable Eric because you find stuff wrong with cars in the rust belt way before we in the south do. Think of it like you are a news network and have breaking news all the time. lol
Remember the engineer that put the battery under the back seat of a Buick I think? I'm glad his kids found jobs at Chrysler.
Ironically they’re still under the passenger seats on some dodges and jeeps.
When I worked on 1960s VWs I thought that was standard. One gal kept all her dirty laundry in the back seat - uck!
My Acadia took me back to my 49 Chevy pickup with a battery box in the floorboard, except the GM engineers decided to size the box to a few millimeters larger than the battery case and hide it in the floor behind the front passenger seat. First battery changeout I was lucky I could dead lift it out using my index fingers.
Think his kids were dropped on their heads a few times before graduating engineering school
I have ia 2002 Lesabre with battery under back seat. Don't really mind,. one place is as good as another. Besides there is not much residual room under the hood of a 3800 engine.
Eric, I come to watch you wrenching. Yeah the interesting problems are cool, or the trips to the scrap-yard, but it doesn't matter... Just anything you want to put on Camera works for me! Oh and a healthy dose of Mrs. O, Luna and the dogs... Always a treat to see the whole family!
That is an awful lot of work for a few batteries.. Ton of connections.... I though the Ford Escape ones were bad... wow...
This repair was so intense it had me on the edge of my seat
22:30 "Please Refer To Manual" is not one of the more helpful error messages I've seen.
I watch anything you post because your videos are educational and they make me laugh I'm not a mechanic I'm just an EMT
I'm subbed to.a guy who washes dishes... I'm guessing in a restaurant but since he never talks and only mentions his "onlypans" account, I will watch anything. I just enjoy your channel. Thanx for the effort it takes to do it. Look forward to seeing you hit a million
Just did the fluid film on my truck let’s see how it does
Mister O, you might think it's boring and run of the mill, but a lot of us are screaming YES I need this one!
The days of the 2 minute battery swap are obviously long gone. And now you have to buy a vehicle specific battery to fit all of the do-dads. Geez!
Auto Zone loves when these come in
You changed parts without doing diagnostics first? What channel am I watching? 🤣
Go to the nearby parts store for a diagnostic. They can Diagnostic your vehicle free of charge and sell you the part you need in a jiffy.
The 20 year old kid is a qualified technician. He can swing the diagnostic tool with the pro's.
@2nickles647 Just because someone can read a code doesn't make they can diagnos what caused the code.
Your torque wrench sound is hilarious!
No bad ataw Mr O. You got nearly 25mins outa that job 😊
Minimum charge 1hr?😂😂
Yup, his labor is not free, 😂😂
Had to go back and check because I didn't see you tighten the positive terminal om the main battery but upon review I saw that you did. Good job. Love the varied subjects of your videos. Very helpful for the DIY guys.
Looks like they purposely made the batteries a bit of a pita to get to and a bit intimidating for the average joe to change himself. I could be wrong of course, but I wouldn't put it past some automakers to do that.
Agree! But must say at least they are in the engine compartment and not in the wheel well!
Most new cars you have the battery programmed or it won't charge properly it won't recognize the new battery
Jeep Compass - one of the first non-jeeps but wow that's a lot of sand and dirt. Great video nice cameo of the Missus.
Not as bad as my ford escape battery replacement. But, interesting none the less.
Videos like this make me enjoy the fact that my trucks are a 1992 and a 1978. Both are my daily drivers depending on my day.
The reason for the red tab thingy, Is to keep from putting twist force on the post when changing fuses.
What an engineering debacle.
I got a charge out of this video. Thanks, pop pop. I hope you enjoy your day.
Wondering if these systems cause premature failure of the batteries. Should most batteries last 7 years? Love your factory spec click click.
Not many batteries around here make 7 years. More like 4-5. Maybe its the cold northern winters.
Down here in Florida 4 years maybe 5
@@rogerdedrick373The batteries on these start-stop systems can last for 3 years and depending on situations and circumstances. This summer has killed alot of them.
Love the basic videos! Keep them coming! I’m here for Eric!
Another quality American vehicle , I wonder where it is assembled ?
Mexico
Even the everyday mundane is beneficial to someone watching......nice relaxing video
Case and point.
Now that was riveting stuff Mr O. Much better than watching paint dry!!
On another note. Regarding the start Stop system. Although they claim the reason why they’re installing them is for fuel efficiency. Truth is it doesn’t save much fuel. If anything as the vehicle gets older, just like any other vehicle and starts to become a hard to start. I would think the start stop would become a liability. Another words if you’re driving along and you happen to come to a set of train tracks. The vehicle shuts off and then when you need to go, it struggles to restart because of either poor maintenance or simply wore out. Not to mention, the amount of wear and tear on the starter and the battery system. Just my thoughts.Ron
Nope, it's the people who ignore the maintenance on their vehicles.
It brakes down on the train tracks.
So they blame someone else or anything because they refuse to get it maintenance because it cost to much.
Actually this is a real issue. My neighbor's Audi experienced just that - stopped at a light last winter and wouldn't restart. Expensive flat bed ride to mechanic later it was operational once again.
Most modern vehicles aren't using the starter for the stop/start feature, they use the alternator/generator to restart. You'd be surprised how much time adds up. Hours a year of idling saved, you do that across millions of cars and that's a lot of emissions saved.
I was in our little town and a car won't start at a light. The amount of gas that was saved by car would not offset the expense of getting car towed and 2nd battery. You can save a good bit of gas with driving habits, tire pressure and maintenance
I’m not a fan of the auto stop start because it feels like my vehicle has a tiny period of time where the car is unresponsive between the stop and the start. That non response is very discernible between my taking my foot off the brake and pressing the accelerator pedal. In city driving, merging from a stop into traffic, it’s enough to make me feel just a little uneasy.
Keep up the great work, Mr. Eric. I hope you and the Better-half have a great weekend!
