You saved my ass …I’m just coming back to this comment to thank you …..I put a rubber glove over my positive and I’ll be damned I pulled that battery out and didn’t that damn wire flip right out and smack the inner fender of my truck….if the glove wasn’t there I’m positive I would have pop some fuse or even worse…..THANK YOU SIR
Wish i found this video soon. Too late . My engine was violently shaking after swapping out my battery. Lost all presets and memory of how my car was supposed to run. Well now I know.
I used the same method but I only needed a 9v dry battery to maintain the memory whilst I swopped the car battery. I made sure that all lights including the courtesy (door open) light was off and that the infotainment system was off. It worked fine.
there's an additional step that might be necessary. The battery monitoring system will need to be reset, coding the new battery to the car, allowing the charging strategy to be adjusted for the new battery. You'll need a suitable diagnostics scan tool for this, or might need to pop into a garage or dealer that has this equipment. The car will likely run just fine on the new battery, but an incorrect charging strategy could reduce the lifetime of the battery.
I have a 2008 Kia Optima 2.4L and any time the battery is disconnected even for a second the computer loses its fuel settings and the car takes forever to relearn how to properly make the engine run without dying. I believe I have a bad ground and want to disconnect the battery and work on that. So I'm about to use a battery saver to keep my fuel settings. Just wanted to see someone else do it before I did it wrong and fried my car. This video is great and luckily I read some other comments that noted you should cover the positive battery cable when you remove it so it doesn't ground out while using a battery saver. My kia doesn't have that nice positive battery cable cover like the one in this video.
Most folks don't have another car battery layin' around. Many do however in the form of their riding lawn tractor battery. Just run it up alongside like you were going to do a jump start.
Showing a 12 V accessory to plug in your computer saver, is OK if you have one. It would have been better if you would have also shown how to connect if you don't have the peripheral equipment.
Could a external power supply be connected to the battery terminals during the battery replacement as an alternative to a OBDII memory saver? I'm thinking if I keep power on the terminals then the objective would be the same. thank you
In theory it should be able. If your charger can output enough amps. Also some chargers don't output anything if they can't "feel" a connected battery. Just be sure NOT touching the chassis or short circuit will happen. Also it is a hassle to keep the cables connected to eachother and moving them around and not shorting so...
What happens if you lose your settings? How can you restore them? The guys at the shop changed my battery and didn't do any of these. Now i have none of my settings even if they are checked in my car settings menu
just have to drive it and they will restore themselves after awhile. drive it in all situations. low speed+highway+ but they will always reset. gm products are absolute worse for a quick reset. other cars will vary but gm takes forever!!! dont use cruise control when driving+it will take longer.
I’m trying to reset my PCM If I leave my battery off for few days Then fit again will the PCM reset then I’ll do the running ecu relearn it’s an rx8 with p0610 code
Why can't you just use the jump starter cable and connect them to the car battery terminal, like a wire or something and then remove the battery while the car is still actually connected to a power source. Then when you reconnect the car battery terminal with the car battery, you can remove the wire and disconnect the jumping cable.
Can be done. This is cool idea and it works. TBH HOW many people is going to be changing the f.. ing battery more than twice in its lifetime Let alone buy this memory saver shit
I was thinking the exact same thing...my battery-powered jump starter puts out 12 Volts and has alligator clips...will be a breeze to use that method instead.
Can be done with a car charger or using a pair of jump leads. This is a better and cool idea and it works. TBH HOW many people is going to be changing the f.. ing battery more than twice in its lifetime Let alone buy this memory saver shit
I understand what you are trying to point out when replacing old battery with a new one the sitting and the memory won't changed/ will be reset why not just start the engine before you removed the old battery and changed thank you
Does the jump starter's amp matter? Because I was told the obd2 port's fuse is around 5-6 amps. BTW some newer cars need a scanner to program the new battery.
All cars have fuses. If you are lucky, fuses will blow and protect the electronics. However, there is no guarrantee you will be that lucky. My advice is DONT PUT THE CABLES ON BACKWARDS.
DO NOT PUT THE CABLES ON BACKWARDS!!!! In a rush to try and sell a vehicle that had a dead battery I fried it by putting the cables on backwards... only cost me about $250 bucks because I sold it for scrap instead. Just a well lesson learned!!!! It could've just as easily fried a much more expensive vehicle.
So the memory saver device is $17.00 and then I have to buy a battery for $150.00 to power the memory savor. And then keep adding water and charging the $150.00 battery until next year when I need it again. Sounds good to me.
Plug in to your OBD II port under the dash first. (If your battery was giving it enough voltage before you disconnect the battery, this will prevent interruption of power to the computer, if your batt is already dead, it's too late anyway, so no need to use the memory saver). Now connect it to your power source. Another car works, or even another (good) battery, but probably NOT your new battery... I think, I thought at first to use the new battery but I don't think you can, since you have to disconnect the clamps from the memory saver to install the new one, on most batteries. If the disconnect of the clamps is momentary, it still might hold your computer settings, maybe - but i wouldn't try it unless there is no other way.
I used a Memory Saver that uses a 9 volt battery and plugs into a 12 volt power plug; oddly, the radio station pre-sets were saved but not the radio/sound system calendar and time settings. The seat settings remained the same but then I have manual seats....hahaha. Any idea why some but not all the sound system settings were preserved?
I guess I got lucky I changed my battery on a 2013 Sonic but after learning about this I don't think I would do it again without that memory saver . I wasn't worried about settings since I didn't know I could lose settings but I heard it's bad for the computer to remove battery then put one in again .. but then why do they use that method to re set the computer to clear engine codes ....
atticstattic when you start the car again you need to leaving running for 15mins to learn tick over then go for a drive and drive slow no heavy foot driving so the ecu learn again
You can, but you shouldn't. You'll get a big spark when you connect the battery, because of the voltage difference. Also, if you short the positive terminal, you could ruin your alternator, maybe even your car computer, who knows. Not a good idea!
I was thinking the exact same thing...my battery-powered jump starter puts out 12 Volts and has alligator clips...will be a breeze to use that method instead.
Why WHY?! Are nearly all the videos about changing car batteries all about new cars!!!! I just want a video that shows me how to change the battery in my 1980 ford bronco! I know when doing this it won’t screw up the fanciest thing in the car, the ashtray! UGH!!!!! Everyone is always promoting a tool, a spray…! If most of us can’t afford gas right now how would we afford all the tools? The battery was expensive enough!
Lol, i guess because this is a KIA, you don't actually need to do that with a Honda or Toyota, and who needs to change a battery after only after a few years. get a good battery that will last you 8 to 10 years. never had to change a battery in my cars that were less than 7 or 8 years old.
Not true with the Honda Fit. Search all the RUclips videos on swapping out the stock 151r dinky battery that Honda saw "fit" to install with a larger 51r. I love my Honda Fit but just can't understand why Honda continues to install the 151r all these years when it is clearly not up to the task in cold weather environments of North America.
Losing is to lose something. Loose means not tight. No such word as loosing. This guy is showing how not to lose something. He is not losing the car settings..
When using a memory saver the positive cable stays hot, put a rubber glove over it so it doesn't ground out.
Exactly, any quality memory saver will include that in the instructions.
Thank you for pointing this out - very Important!!!
Thanks

Hands down. One of the best videos out there that shows clear steps and showing safety steps properly
Wish i found this video soon. Too late . My engine was violently shaking after swapping out my battery. Lost all presets and memory of how my car was supposed to run. Well now I know.
I don’t have a small power source , can I connect the positive and negative cables to another cars battery ??
I'm about to change my battery, it's very important that I have to watch this carefully
I used the same method but I only needed a 9v dry battery to maintain the memory whilst I swopped the car battery. I made sure that all lights including the courtesy (door open) light was off and that the infotainment system was off. It worked fine.
It was a good video on how to save your presets my question would be why would someone put a new battery in and not clean the cables?
and after cleaning them use die-electric grease

I've replaced batteries in a 05 lexus, 15 sienna, and a 16 Altima. Never used the memory saver and they still had all their memory.
You're one of the lucky ones
It all depends on the car you are working on - they're not all the same
I have a 2007 Toyota Sienna and have changed the battery without a memory saver and haven't lost memory. What year cars did the memory loss start?
I have a 2008 Kia Optima 2.4L and any time the battery is disconnected even for a second the computer loses its fuel settings and the car takes forever to relearn how to properly make the engine run without dying. I believe I have a bad ground and want to disconnect the battery and work on that. So I'm about to use a battery saver to keep my fuel settings.

It varies widely depending on year/make/model. Some makes and models have been doing it forever, some just started a few years ago.
2002 3.1 pontiac grand prix will lose settings if battery disconected. i need one.
I can't remember
Just use an extra fully-charged battery on the side to power using a jumper cable.
Most folks don't have another car battery layin' around. Many do however in the form of their riding lawn tractor battery. Just run it up alongside like you were going to do a jump start.
Should you have wiped a little grease on the battery terminals after installing?
Showing a 12 V accessory to plug in your computer saver, is OK if you have one. It would have been better if you would have also shown how to connect if you don't have the peripheral equipment.
It doesn't save all the settings, it just keeps power to the car.
Could a external power supply be connected to the battery terminals during the battery replacement as an alternative to a OBDII memory saver? I'm thinking if I keep power on the terminals then the objective would be the same. thank you
I was think the same. Did you get a positive reply to this from somewhere? I was thinking of connecting a battey tender to the terminal cables.

Just be sure NOT touching the chassis or short circuit will happen. Also it is a hassle to keep the cables connected to eachother and moving them around and not shorting so...
Just hook up a battery jump pack to battery leadstake battery off, replace battery connect leads, unplug jump pack, job done
Thank you so much, you made it clear and easy to understand

Newer cars will likely require an expensive $500+ bi-directional scan tool to reprogram different parts of the system
I’m trying to reset my PCM If I leave my battery off for few days Then fit again will the PCM reset then I’ll do the running ecu relearn it’s an rx8 with p0610 code
I'm positive about the negative, but a little negative about the positive.
So if you plugged the booster pack into an always on cigarette lighter port would it work the same way?
Why can't you just use the jump starter cable and connect them to the car battery terminal, like a wire or something and then remove the battery while the car is still actually connected to a power source.

that was my question couple minutes ago...did you get an answer?

On older cars, that would work. On newer cars, it will damage the charging system.
102.3 you must be in Florida thank you for this video
Is the cable long enough to reach a nearby car?
Does the jump starter's amp matter? Because I was told the obd2 port's fuse is around 5-6 amps. BTW some newer cars need a scanner to program the new battery.
I though you can just use a 9v battery memory
Is it true when polarity is reversed, car's computer hardware will be fried?
All cars have fuses. If you are lucky, fuses will blow and protect the electronics. However, there is no guarrantee you will be that lucky. My advice is DONT PUT THE CABLES ON BACKWARDS.

Hi, Ryan, what State do you live in? Looks nice!

If you dont use the memory saver. Will it forget your car fob signal to start car?
No, it wont
Why install the mounting bracket before black cable? Just curious.
Just a safety to keep from grounding. Once the circuit is complete anything that touches the frame and a hot wire can short.
Change it with the engine running . Simple as that
Very nice explanation.
Thank You!
Thanks!
When I'm using the memory saver, do I connect the clips together with the device on or just connect it

why can't you use the main car battery as the 12v source?
Very clever!
Hahaha, ummm because you're changing it?
@@CoffinNeAler no. ppl need to do other stuff with the battery disconnected without losing memory, not only changing batteries.

Not necessary for any year car

NO

A jump box connected to your cables does the exact damn thing. Any auto parts store will do this for you or just borrow a jump box.

Never lay a metal tool on the battery.

Let the car idle vile you change the battery, get someone to hold the positive led
NEVER
