Low voltage battery

[ime2019]

Hello all. I just received s notification of low voltage battery and to replace it. Is it safe to charge it in the meantime since the main battery charge is down to 20%?

Thanks

Assuming you mean the 12v low voltage battery needing to be replaced. Yes - it is safe to charge your car.

In the meantime, plan on changing your 12v sometime soon.

Putting a 12v charger on the jump start points may help. A mobile Tesla charger plugged into 110v could also help.

definitely keep the main battery charged, as that feeds the 12v and if the main battery gets too low it will stop charging the 12v and if the 12v goes dead you can't unlock your car or open the doors. Suggest you keep the driver's window rolled down if parked in your garage.

My LVB warning light came on Sunday, and Tesla mobile service can't get to me until next Monday (8 days). How long have people driven their car after the light came on? i just drove it today and didn't see any issues, but don't want to get stranded somewhere or damage something. i'm keeping it plugged in when not driving just in case.

As others have stated, leave it plugged in, and if garaged I would leave the drivers window down enough to reach in and unlock if the 12v dies completely.

I've gone three weeks. I wouldn't go on any road trips but you'll be fine for 8 days local driving.

Keep Sentry Mode on at all times, so the car never goes to sleep. This keeps the DC-to-DC converter active, which is what charges the 12V battery. It consumes some waste energy keeping Sentry Mode on, but far better than ending up with a dead 12V.

Thanks for all the tips. Tesla replaced my battery a few days ago, and for some reason didn't charge me for it? My car has the extended warranty but I didn't think the LVB was covered by it. I didn't even pay the $100 copay.

I just got the 'replace low volt battery' alert, booked a mobile service. Approved the esitmate for $176 (in CA), the tech arrived and said the estimate has been udpated to $276 and unless I approve it they wont do anything. Given I just went out of warranty, in Jan, I thought they may take that in to consideration and may not charge...and how wrong was I! I sent the tech back, reached out to the SC to talk to them, but they dont talk to anyone! Do we have any other option for replacement or do I have to be extorted by the SC everytime there is an issue? Looking at some you tube videos, and this looks pretty straight forward. Just not able to determine what battery to buy. Appreciate any feedback. Thanks!

You can go to the SC to purchase a battery. There's a chance that a part on top might not fit perfect so a second trip might be needed for an adapter.
