What is 12v battery replacement cost

[ShawnA]

Hi SemiS3XYR,

I had the 12 volt battery replaced last week. (8-5-2020)
$165 for the battery and $70 for the labor.

I proactively replaced the original battery on my wife's 2015 Model S 85 D.

I have the same question: has anyone here used the Lithion replacement, pros and cons?

I Had to get replacements every 18 months for my car battery. Decided to go ohmmu this time since im out of warranty. Working fine so far. If I never have to change it again, it was worth it
I made a video about the installation

Tesla quoted me $230 for their car battery which only lasts me 18 months.

@SemiS3XYR ; May I ask why you are not interested in Ohmmu?

I am but I'm not sure if I will keep the car much longer (our priorities have changed)
I'm not sure when the last time my batter was changed since I am second owner. A lead battery can last all various time frames it seems like. The cost difference between the two options is not significant but still something.

@ShawnA thanks for the info!

I've made an mobile appointment but its not for 3 weeks!
So are there any non oem battery recommendations? before I get locked out of my car OR is there a temp solution like charge the battery up

Had ours replaced for the first time on our 2015 Model S 70 back in December 2019. Was charged $240.41 and it was done as a mobile visit. The part listed on the invoice was (1083774--00-A)

Thanks for the video!
Did you ask Tesla if they had any issue with you installing it? The Ohmmu site says it is fully compatible - but they would, wouldn't they?

I didn't contact Tesla.The battery was indeed a drop in replacement. Ohmmu has been around for a few years so Im not really worried about compatibility.

$165.00 parts
58.50 labor
12.79 tax

New battery in my July 24th 2015 P85D was: Battery, 12V, DCS33-UNCR(1083774-00-A)

 

[adspguy]

installed by mobile service it cost $215 for me a couple months back

 

[SemiS3XYR]

$150 is much more palatable than $400
@BrokerDon nice car! exact some over here. Thanks for posting part number

Those all in on the lithium batteries is there anything other than their marketing material that has convinced you it is the right choice?

Have an understanding that lithium should be be charged below freezing?

I never found a single negative thing about them, So I was convinced. I wish I could give a better review but only time will tell.

Replaced battery but msg is still present. Can’t find the old battery date. Or not looking hard enough. Was wondering how old it was but it was pretty dusty. Process was pretty okay and 30min. I put the old battery on a charger and it read 95% and charging so I hope it’s not another issue that I’ve read some posts mention.

I read the error msg will clear itself after some miles, or after next deep sleep, or after a deep reset, or something about unplugging HV contactors (which none of the YouTube videos I watched doesn’t mention). Tried a few miles and a deep reset and it’s still there.

Any tips??? TIA

Why even replace it? Just remove the fireman loop unhook the 12v battery and load test it. If it load tests good put it back in as its simply a programed death based on cycles. They can't say *sugar* about warranties when the original serial numbers matching battery is still there. Disconnecting the 12v restarts the battery obsolesces cycle count.

When these batteries start to go you can usually tell by the main traction battery contactors firing slower when you put your foot on the brake for initial startup.

At the factory, a surprisingly high (double digit) number of these batteries fail the cars initial voltage self testing and got replaced. MRB has pallets stacked almost to the ceilings awaiting vendor credits or RMAs.

@Cory151 mine was actually starting crazy slow... like 20-30 seconds wait and started a few months ago. Maybe it’s the original? Mine is 2015 model, red battery

what’s done is done... how do you reset the msg?

 

[SemiS3XYR]

Interesting posts here.

How do clear "replace 12v battery" warning?

1) Disconnecting the FRL is hard on contactors (not sure what that means)
2) someone said doesn’t guarantee cleared msg
3) change wheels size for deep reset...

 

[SemiS3XYR]

So my car boots regular speed with the new battery and no slow as molasses.
AND changing the wheel configure cleared the msg!!! Thanks TMC!

I paid about 160 at the Dania service center last month. P85D took me about 30 minutes to swap the batteries.
