Mine died with no warning (no messages, no errors, no sign of it failing). Very annoying. Then again, only issue I have had with my MY in the three years I have owned it.
FYI, i've seen a dozen videos claiming you can pop the frunk with a 9v or those small 12v batteries but not always! I helped a friend on his model y and tried both but they did not work, his 12v was REALLY dead due to his heat pump sezing and the high voltage battery would no longer charge his 12v. To open the frunk i had to use a lithium ion booster pack with the 'boost' feature turned on. Same to open the doors. So beware, those smaller 9v and 12v solutions may still leave you stranded, always have access to a booster pack.
Yes I had this experience recently and luckily I was at home and got the one I had in my other car. Otherwise that's the catch22! If you carry one in your car, you can't get to it bc to get to it you need it to pop the frunk!
My 12V battery died during an overnight software update. I live 450km (inland Australia) from the next service center. The software update was incomplete and the car not chargeable or drivable. Luckily i knew how to open the frunk and luckily (again) my ride-on mower battery fitted in ok. Tesla Service then shot through a new update ota and all was good. Car was not happy about the foreign battery but i dove for a few weeks until i needed to go to the coast and getting the right battery then.
5:35 I'm pretty sure that I read a 9v battery will allow you to open your hood? UPDATE: the 12v looks like a better option as I've seen mix results on the 9v. Alternative way to keep the 12v is here: YT Tesla Model 3/Y - Hide An Emergency Battery - Tesla Tips by MTN Ranger
I’ve just changed the 12V battery in my 2017 MX for the second time preemptively because the consequences of letting the battery die are so serious. I change the big HEPA filter (“bioweapon” filter) at the same time, since it has to come out to access the battery. Changing the battery every three years is a good guideline.
My 2018 just notified me of an issue with the 12 v battery. No issues setup appointment on the app along with a brake cleaning had it done 2 days later for a grand total of $275. No fuss no muss. Love tesla
Every year during my annual maintenance routine, I test the 12v battery. I changed it at 2 1/2 years. Also, the negative terminal was green and crusty, so we did a normal battery service. Sadly, the owners who believe their cars do not require service are mistaken.
5:30 seen it been opened with a standard 9V battery also when the car was completely bricked… It even got the doors to unlock and to restart the computer…🤔
My car was dead this morning and it never showed me a warning. Of course, my car is a lil over 3 years old. Service wants to bring it in to check the whole car out.
My 12 volt died in less than 3 years with no warning. Totally inconvenient but it was replaced for free under warranty. The service tech came out and was finished in less than 10 min.
There’s also a place in the service menu with the voltages and health displayed. I’m guessing that if there’s a problem the error notices might pop up at the same time as anything shows here though
Awesome. Thanks for all this information. I knew about the 12 volt battery, but had no idea how long they last. I live in Northern Illinois, so we also get cold winters. Thanks for all the possible warning signs. I got my Tesla August 2023 and hopefully good for a while with my 12V battery. Thanks and take care.
A few important points that need to be emphasized. Since 2022 the lithium 16 volt battery has replaced the 12v battery and the lifespan of these batteries is 8-10 years and may be covered under the standard warranty. I believe that 12v will still pop the frunk in systems with the 16v battery. The system is designed to not allow popping the frunk from the accessible wires unless the battery is really dead thus preventing frunk access by thieves.
Mine went dead without any warning whatsoever after 2 and 1/2 years. Tesla sent a tow truck and towed the car to the service center. It's the only issue I had with my model Y. The Tesla technician said that there must have been a sudden drop of voltage, that's why there was no advance warning.
I have a 12V battery jumper/charger thing that I keep in my trunk. If my 12V battery dies, can I charge it with that device and use it again, or would I be better off just buying a brand new 12v battery instead?
My Model S warned me that it was time to think about a new 12v battery, and Tesla Service actually offered the best price; came and changed it in my driveway. No drama.
If y'all changed the electrical system for the install using aftermarket it will void the warranty, do your due diligence and check for yourselves; things could've changed in the last year?
Unfortunately, no. The exterior handles only activate the electronic actuators, while the interior emergency handles (driver and passenger doors) are fully mechanical.
@@jamesbuckingham8073 That's interesting. Did they keep the 12v for 2022 only on the Performance model? My 2022 had the 16v, also my 2023, but my 2022 was long range, my 2023 is LFP
Does the 12V battery run the wi-fi system? I find it nearly impossible to connect to wi-fi for SW updates. The car and battery is nearly 4 years old; only have about 6K miles. If the battery is failing and I get Tesla to replace under warranty, would they replace with a lead-acid battery or a lithium battery?
Tesla would replace the battery with the same type- lead acid would be replaced with lead acid. And that’s super low miles for 4 years!! I have nearly 10x that in half the time 😂
so if your car's not moving and you're watching Netflix, playing games on the infotainment screen or listening to Spotify, this depletes your 12v battery and could cause the car to die on you????? If so, that's just a joke, having a battery under you that could power a house, but instead you're using a small 12v battery. Please tell me I'm wrong! I'm contemplating buying a Tesla and wanted to use the car's entertainment options frequently while standing still (downtime away from home), but this would make it impossible.
No need to worry! The high-voltage battery is tied directly to the 12v battery, so you can keep electronics powered on indefinitely, so long as your big battery is charged. The problem is the 12v battery (like any car) loses overall capacity over a few years, and the car can't run without one. Hope this helps!
@@cybrtrkguy Thank you. if I understand correctly, all this stuff gets powered by the 12v battery, but the 12v itself gets recharged by the big battery? Only when the 12v battery has deteriorated and can no longer load to 12v, you will have problems.
When the car is awake, there's constant power going to the 12v battery (either to charge to maintain). Only when the car is parked and Sentry is not on, is the 12v isolated and on its own
@Troy Meekhof You get it wrong here. Usually, batteries in cold climates hold longer than in hot climates, but capacity is lower with low temperatures. On cold days battery performs worse, but holds even twice as long as in hot climate.
My previous ice car batteries died a month or two around the time the warranty was to expire. I.e., 36-month battery died at 36 +/- two months of warranty.
A lot of times the car won't give you warnings. Also lead acid batteries last no more than 2 yrs, if you're lucky, so check them at 18 mos. Then replace with a Iithium battery. They last about 4-5 yrs.
You can't pop the frunk using the jumper unless the Tesla is unlocked or the 12v battery is completely dead. So a thief would have to time it just right... unless they used a crowbar.. buy yea, prob shouldn't keep anything of value in a car anyway.
You obviously have not heard the expression: "flogging a dead horse"... It doesn't work! Any "solar panel" power will be short cirquited by the bricked battery. (that's why it failed in the first place: sulphur-phosfate spikes that has grown over the years between the lead plates, and rendered the battery useless)
Not true. You got lucky that it notified you, but it doesn’t always. In my case, car was working perfectly, then at 12:07am I got an alert on my phone that the battery is dying. I am already asleep. I wake up, and doors don’t even open. So yes, you should be aware and alert about these problems because you won’t necessarily get an alert.

Same happened to me with the M3. 80K miles on my second battery. I had to use a portable jumpstarter to open a frunk
FYI, newer Teslas are equipped with li-ion batteries operating at 15-16V, rather than traditional lead operating at 12V
Can I get one when my lead acid battery dies?
@@carl-SpNo

I replace batteries in all vehicles every 2 years. Trying to squeeze over 3 years out of a battery is stupid.

Great video Troy! I’m hoping that I get a long life out of mine because it’s the lithium one 🤞
You make it sound as though this is an EV problem. All cars have a 12 battery. My ICE car is 7 years old. Battery still going strong.
It is. Nothing is charging it.
12 V batteries in EVs do tons more work than in ICE cars, so they degrade about twice as fast.
@@txtabbythat’s untrue, if nothing was charging it, it would be dead after a day 😂, it re-charges via the high voltage battery
a standard 9v batter will open the frunk too.
Does Tesla service perform 12v battery replacement
Yes, they do. Depending where u live, they can even come to your home to replace the battery.

Not an accurate statement; Have a 2022 MYP, checked; it is a 12V lead acid battery
Mine went dead without any warning whatsoever after 2 and 1/2 years. Tesla sent a tow truck and towed the car to the service center. It's the only issue I had with my model Y. The Tesla technician said that there must have been a sudden drop of voltage, that's why there was no advance warning.
of course if you worried you can replace the 12v battery early right?
Interesting insight about the distribution deal they would have had with Suge Knight, Irv Gotta, Puff Daddy, Dame, and Jay Prince!
I have a 12V battery jumper/charger thing that I keep in my trunk. If my 12V battery dies, can I charge it with that device and use it again, or would I be better off just buying a brand new 12v battery instead?
Those battery jumper packs are for emergency use only . Once u start using one of those its time to get a new battery
Several garage door remotes run a 12 volt battery.(like the one described)
Great point. Most of us carry such a garage remote all the time. Thanks
My Model S warned me that it was time to think about a new 12v battery, and Tesla Service actually offered the best price; came and changed it in my driveway. No drama.
How much did they charge you
will the 12v battery open the frunk latch if the car have aftermarket auto-frunk installed?
Auto frunk have have cable to pull out to open frunk.
If y'all changed the electrical system for the install using aftermarket it will void the warranty, do your due diligence and check for yourselves; things could've changed in the last year?
9v battery works to pop my frunk.
Aren’t the exterior door handles mechanical? I know there are interior mechanical door handles
Unfortunately, no. The exterior handles only activate the electronic actuators, while the interior emergency handles (driver and passenger doors) are fully mechanical.
I have a 15V and its lithium in my 2022 Model Y
I got the warining a day after the car would no longer start.
Great video, very informative thank you.
What about low voltage battery?
That’s the 12 v
Actually I learned just yesterday that the Lithium Ion auxiliary battery is actually 16 volts.
not compatible with 12v lead acid system
Tesla is on 16v last few years.
Not accurate, have a 2022 MYP; came with 12v lead acid battery

@@ivo4357 You got it!
When does the 12v battery charge? When the main battery is charging and/or when the ignition is on or both.

How's your brother Jack doing?
Bro clean your screen holy hell 2:00
what is the average life of a 12V?
3-5 years usually, less in cold climates

Lithium battery is a 16v and not compatible with former 12v lead battery system. Do your own research.
Yeah but my 12v just died without warning. Had to use the frunk cable and then jump start my car.
There is a way to open the doors on a dead Tesla. I saw it on RUclips.
Very sad that someone has destroyed the fine video with annoying backing muzak. Hard to understand the speech, when the loud noise is on.
So..I learned not to place any valuebles in the Frunk 😅
You can't pop the frunk using the jumper unless the Tesla is unlocked or the 12v battery is completely dead. So a thief would have to time it just right... unless they used a crowbar.. buy yea, prob shouldn't keep anything of value in a car anyway.
This is why every auto with a 12v battery should have a small solar panel to maintain the 12 volt battery.
You obviously have not heard the expression: "flogging a dead horse"...
It doesn't work!
Any "solar panel" power will be short cirquited by the bricked battery. (that's why it failed in the first place: sulphur-phosfate spikes that has grown over the years between the lead plates, and rendered the battery useless)
I just replaced the 12volt battery in my 2020 Model 3. There’s no guesswork or drama, the car indicates when that’s due. No need for this video.
Not true. You got lucky that it notified you, but it doesn’t always.
In my case, car was working perfectly, then at 12:07am I got an alert on my phone that the battery is dying. I am already asleep. I wake up, and doors don’t even open.
So yes, you should be aware and alert about these problems because you won’t necessarily get an alert.
