POLL: Have you had to have your 12V battery replaced?

[Skotty]

Warning light just came on. Model S, Year 2014, 24,600 miles

Mine just came on maybe a week or two ago. 2014 Model S. Bought CPO, so don't know if it has been replaced before or not. I've had it for about 2 years. Came on starting with the much colder weather here. Replaced under warranty.

Update, looks like the last battery I got has only lasted me 12months and a couple weeks, convenintly just out of the 1yr warranty. 21k miles and driven every day, plugged in most every night.

2014 S85

got the warning light that it was about to die at 28k miles... 2014 P85+
so i am on battery #2


what baffles me is that the warning light came on the day after Tesla had my car for 2 days

 

[Benjamin Brooks]

On to 12V battery #5! Averaging slightly over once a year replacements...

 

[croman]

12V #1 lasted 9 months. 2nd one is still going. 14 months of ownership.

Still first battery delivered July 2016, 52,000 km...

12v was replaced yesterday as goodwill, no cost to me. This was considered as an abnormal failure for this battery so hopeful the new one lasts the expected 24months

Nov-2013 P85+, original 12V battery replaced today under warranty after 72k km.

 

[eschummer]

That's quite impressive! Is it possible that the near-annual failures reported here and elsewhere are a newer phenomenon and the earlier batteries were actually longer lasting?

 

[tormodl]

Well, difficult to say. At least I haven't seen any stories on the Norwegian Tesla forum that any owners here in Norway have had near-annual failures.

In fact, I have seen very few threads on the matter - of course there have been some - but taking in to the account the numbers of Model S and X here now surprisingly few.
As per today, there are 16765 Model S and 6899 Model X registered in Norway.
I have been reading the forum regularly since 2013, and not noticed this was an issue until it happened to me and started searching for it.

Maybe the cold climate we have is good for the 12V battery ?
I live in Stavanger on the west coast, and it seldom get very cold or very hot.

Picked up new S75 on 3/20/18. Today is 4/7/18 - less than three weeks and 500 miles later. Got the 12v battery warning. Tesla says they will contact me when ready to install a new battery.

I got the message @ 1100 miles on my 3/2018 S75D and it died the following day. Tesla currently has my car.

 

[iffatall]

My original 12V battery died at about 38k miles, after 34 months of ownership in Oct 2016. The second battery is dying now at about 50k miles, after 51 moths of total ownership. So the second battery lasted less than 1.5 years.

First 12v battery after two weeks and 400 miles -- 2018 75D. Ranger came to house and replaced following day.

 

[mknox]

Many battery replacements on my 2013 S85 over the years. Most recent: December 2017, then March 2018.

New 2018 Model X 100D: Replace 12V Battery error in the first week of ownership. My local Service Center is out of stock and looking to a Service Center further afield for one.

Yikes! Tesla told me that you are usually good for 4-5 weeks after the message appears.

I had a Takata airbag replacement this week and during the repair (mobile service at my home) the tech noticed the replace battery warning light was on. This will be the 3rd battery in about 5 years and 105K miles. I got about 2 years out of the last one. Interestingly, the tech said Tesla is using a new tech in these now, called it a carbon nano battery instead of the exide ones they've been using. Cost was $150 plus $70 labor. I chatted with the tech about how I considered doing the swap myself but it looked like a pain to change these on the older generation cars like mine. He agreed and also noted that with the new battery type, there had to be a modification to the charging algorithm so you couldn't just swap in the new type battery yourself without some input/setup from Tesla.

2013 P85 w/ 75,000 miles. One 12v replacement about 18 months into ownership. Knocking wood...

 

[Texas]

Car delivered 5/28/2015,12v battery replaced 6/16/2018, just short of 3 years. This is a typical battery life for my cars in Houston, possibly because the air conditioning is always on. The battery was replaced by a mobile Tesla mechanic who came to my house, covered under 4year warranty.

 

[JasonA-EV]

Early 2015 vin, and last week I just developed a wonky glitch. Called them and they said bring it in. 12v was going out and so is a battery module. Replaced no cost.

My loaner is a 100d!!! Biggest regret is not having the UHFS

But damn this thing is fast!
