Anyone put an AGM Battery in a Model 3?

[Flybyglass]

Keeping replacement battery options open. I know the Model 3 uses a Group 51R battery (same battery of 2020 Mazda Miata for search purposes). I have seen some threads that AGM have different charge requirements and may throw off more errors. So any one put an AGM battery in your model 3?

Thanks

AGMs need different charging requirements, dont have fancy battery management systems like aftermarket Li-Ions, and are also more expensive. What would be the purpose of doing that?

Much of Tesla's 12V battery trouble seems to come from poorly tuned battery management software. Installing some random battery with different characteristics might just make the problem worse, even if it is a better battery.

That said, this is a very helpful video detailing the process of removing the battery, assuming you've already removed the front of the car.

The issue would be the different charging requirement would probably cause errors.
