New Li-Ion Battery for 2021 Model S and Model X

[r1200gs4ok]

I have heard that the new 2021 Model S and Model X will have a new 12v Li-Ion battery.....will this battery be able to be put into a 2020 Model S when it is time to change the 12v battery? thanks in advance

Tesla’s new Li-Ion battery will probably fit older S & X.

You don’t have to wait. Ohmmu has been selling Li-Ion batteries for S & X, also 3 & Y for years. They have a strong reputation. One stumble when the Model 3 battery internal control system didn’t work well after a Tesla update. They did free battery swap for affected customers.

We got a 12 Volt battery warning message on our 2017 S 100D last Fall. Ordered the battery and installed it in relatively short order.

Follow their instructions and video.

• Remove frunk trim.
  
• Leave driver’s window open. Turn off car.
  
• Disconnect First Responder Loop.
• Remove some vents and drains. This takes careful attention to how they’re fastened and gentle pressure.
  
• Remove frunk tub.
  Disconnect old battery, wrap leads to ensure they don’t touch metal.
  
• Remove old battery. I took a few minutes to clean up exposed structure.
  
• Ensure you have the key in your pocket.
  
• Attach new battery. Alarm will sound when power starts. Use the lock button to stop the alarm.
  
• Reverse disassembly.

If you would rather have someone else install it for ~$100, this Oceanside shop can take care of you:

They are an official Ohmmu installation partner and did a nice job for me. Took about an hour.

Its funny I've disconnected the damn thing a few dozen times and it only sets off the alarm like 30% of the time, i do the exact same thing every time: HV loop then neg on the batt, and reverse it back together. I think it has to do with how many times i open the door while working on the car maybe. I dono just an oddity i cant seem to explain.

Both times I disconnected the battery, alarm sounded when I reconnected.

It may correlate with disconnect duration. Both of my disconnect sessions were more than 30 minutes. It takes a while to run out of wrong ways to do something before finally getting it right.
