Need 12V battery recommendation.

[mnm1945]

I have an August build 2018 P100D with 22K miles. I recently got a 12v battery warning light which has not since returned. I assume my 12v battery health is not the greatest and I plan on preemptively replacing the battery when I flush my brakes. Can anyone recommend a brand name and model that fits the Model S battery plate?

Why wouldn’t you get that replaced under warranty? When I was under warranty they did this via ranger service. Unless you have a salvage or something, it should still be under warranty.

Is Tesla still replacing 12v under warranty?

YUP.

Wasn’t sure, thanks Uncle Paul.

Great news. I was under the assumption the 12v battery was not covered.

12v battery needs replacement. Car is out of warranty. Anyone know the battery code or a good place to buy other than tesla

There are several options, original is the C&D Tehcnologis AGM deep cycle lead acid type 33Ah battery.

I ordered the ohmmu because it was the easy option at the time. I was far from a service center and no one else had any.

Ohmmu is excellent choice. Installed this myself in a 2016 Model S 90D. Works so well! No error messages and afterwards I happen to notice that the lights on the car we’re slightly more responsive (activation of headlights, turn-signals). It is so much lighter, and going strong after three years.

Another vote for Ohmmu. What i like most is the weight. Had it for 2 years no problems yet.

Interesting Reddit thread on the Ohmmu here. (disclaimer: I have no strong feelings either way)

Another happy Ohmmu customer here. Installed 12/30/2019, ~60,000 miles and counting with no issues whatsoever.
