I've had my 2023 Bolt EUV Premier for one week. I'm definitely going do this in about three years. Too many stories about the 12v lead acid failing in these. Thanks so much for this video...I will be referring back to it again. One last thing...what's the amp rating on this battery..? I didn't see it on the site. Or how it works when below freezing out.
My 2017 started throwing "Battery saver" errors on the screen about 6 months ago. I just replaced the AC Delco battery for an Ohmmu for this car yesterday. The old battery still kept 12V, but had hardly any ability to pass an amperage test. It surprised me how many systems worked on lower than 12V in this car. But charging and shifting is definitely needing 12 volts.
My 2017 original battery is still going strong with no issues. Took it to auto zone yesterday to have it tested, and it failed…. 7 years on the original battery ain’t bad. Ordered a replacement so I don’t get stranded
Thank you for sharing this DIY. I just want to verify this is an exact fit? Because I think an “H3” is same as LN0, and H4 is LN1, which is what I believe the Bolt takes? (I wish you put them side by side to demonstrate)…
You are correct, both the LN0 and LN1 fit in the Chevy Bolt. Our listing for the Bolt is an LN1 at this time but we will be moving it to an LN0 in a while b/c that accommodates more platforms overall.
I’m curious about disposal of LiFePO4 batteries. Do recycling centers accept them like lead acid batteries or do they have to go to special hazardous waste centers?
Interesting video since my dealer stated that changing 12v is not a consumer replaceable item since they claimed some reprogramming of car is required? Was this not an issue when you did the exchange? The last time the 12v went out on me, the brakes were locked. Had a hard time getting car onto flatbed tow truck, even though we put a lithium jumper box onto the battery..
On the Bolt the 12V battery is very consumer replaceable. I have a feeling the dealer/tech had it confused with the High-Voltage battery which would not be so easily done. The HV battery needs to have some programming to match VIN but nothing needs to be done to upgrade the Bolt 12V to the Ohmmu Lithium (or just replace it in general).
Smart!!! Why Chevy did not do this to begin with! Question: For my normal gas car, I remove the acid based battery when I park the car for 3 months. So will this be the case for this Lithium battery if I need to park the Bolt EV for 3 months?
What are the specs regarding temperature ranges for charging and discharging? I was looking to hardwire my dashcam in my EUV to record in parking mode because currently I use power bank inside the car. Didn't dare to do this with the stock AGM battery as I felt it will kill it too fast cycling it almost every day.
@@OhmmuEnergy from what I'm reading lfp's in general can't charge under 32°f, is there a section on your website guaranteing that it charges under that
I have a 2022 Chevrolet Bolt EUV love your report on the lithium battery..my 12v battery died on me at a bad location and had to be towed to dealership. I want to get a 12v lithium battery for my bolt but I’ve also read some negatives. Now I’m not sure. I really need some reassurance. Any help for my problem?
Great video! Just wondering when disconnecting the 12 volt battery, does the vehicle computer, infotainment system, electronics etc need some kind of reset, or will it remember all settings and resume normal operation?
They don't need reset, they save settings into non-volatile memory these days so even after losing power completely the modules can be rebooted and have their settings reloaded (unlike some of the older stuff in cars where total power loss would scramble them back to factory settings).
I am surprised that you didn't add a memory saver device before you disconnected the original battery. That's needed so that all the computer and infotainment settings are maintained.
When swapping my Bolt's battery, my Home Location was lost in the Infotainment. Which, removed my Hill Top Reserve, and Charging hour restrictions too.
This would save a lot of hassle . Dead battery in an EV can be really annoying. I got my key stuck in the ignition on my Fiat 500e, tried a LiPo battery, very undersized, car died weeks later on the freeway. The Fiat didn't give me enough dead-battery warning ever. I think three years on a lead acid is typical for EVs
Is there any tradeoff other than the higher initial price? I’ve seen some internet “experts” claim regular batteries are better for reliably starting the vehicle compared to lithium
If starting an engine, I personally would go with lead acid. For an EV though, the usage profile and need are completely different. These are the way to go!
All well and good until it tries to charge when it’s 10* zero, THEN WHAT? I notice there is no mention of LifePO4 heating on the website. They tend to self destruct when charging below 32*, what solution does the manufacture have for that?
These batteries are tested in lab down to -30C (way way below 32F); these batteries do not "self destruct" when charging in the cold. But, on that subject, all batteries (including these) do degrade more quickly in the "extremes"; this is true of both extremely cold and extremely hot conditions as well as extremely high/low voltage or extremely high current. The safety limits of the battery can be governed by the BMS but it will surprise you to find out that the safety limits are far beyond what you are suggesting. Oh, and to clarify the "testing in a lab"; this is done in a Thermotron environmental chamber and the battery is subjected to continuous charge and discharge cycles for weeks on end, after this test the battery is placed on a vibration apparatus that simulates the driving environment and "shaken" for days continuously. This is all done to ensure that 1. the decay/degradation is minimal and 2. the battery didn't form potentially dangerous dendrite formations during the test (shaking would illicit shorting). The design of these batteries takes into account the extremes that are potential in an automotive environment.
What do you mean tested you can't charge lithium battery below freezing or you will damage it also it does not include a BMS that you can read with Bluetooth you have no idea about the quality of the cells or anything else that's going on in that battery

I'm 3 and a half years into my ev without any issues, I've read they can last 4+ years since they're not used as harsh as a gas car

Very cool! I'd be happy to see you enter the motorcycle battery market...

BMW i3 12v has to be registered in the computer,I think some others do to

Can you make one for the BMW i3? There's a market for them since the original 12V agm battery does not last long.
Are you in the Phoenix area? If we can get an i3 for a few hours we can do this.
@@OhmmuEnergy I'm in San Diego. I would be happy to lend you my i3 to test out.

-4F to 150F is the recommended range of temperatures. Testing is done to -17F and 167F.

What is the watt-hour or Ah capacity of this battery? Can't find it in the specs on the website.
It is 40 below on the occasional day or so here, how’s that going to hold up ?

@@OhmmuEnergy : good to know, thank you!
The factory battery is AGM not lead acid it says so right on the battery.
AGM batteries are lead acid - just different internal construction than typical “flooded” lead acid batteries.
I am surprised that you didn't add a memory saver device before you disconnected the original battery. That's needed so that all the computer and infotainment settings are maintained.
On the forums I'm reading only the setting that limits charge to 80% is lost

If the 12v battery is completely dead, can you jump it with another car?
Probably, it’s really only used for the AC, infotainment, and lighting, so the car will still start if the battery is dead
thanks 😊

I'm reading that it may have issues charging under 32°f, afaik otherwise they're better, in theory at least
Probably not good in cold weather that is why they went with the other type battery
The battery has a cold weather guarantee probably good except for super cold climates
If starting an engine, I personally would go with lead acid. For an EV though, the usage profile and need are completely different. These are the way to go!
Battery doesn''t need computer registration like BNW i3, yAy!
Complètement inutile de changer la batterie AGM originale .... You save 24.6 lbs ... wow !
500 dollar battery ???? 500 dollar tax we have to pay a year also ???? Make sure you are gonna keep the car for a long time folks .....
