    Can't help, but I'd love to see a lithium based 12V drop-in replacement (assuming that Tesla is still using a large and heavy 12V lead battery). I've read that a lead battery may be mandatory by law depending where you are, but in an EV you do not need the power to operate an ICE starter. I've seen a report about such a lithium based replacement for a Nissan LEAF, which is smaller, a lot lighter, comes with own BMS and eliminates all the downsides of good old lead batteries. Of course there is a catch, namely the price tag.

    The 12 volt battery is an AGM battery.

    Earlier this year I had the car at the service center for other reasons and they replaced mine under warranty even though I had no warning messages. I asked how come they replaced it and they said because it was so old (original battery from July 2013). So you may want to check if they'll replace yours for free also.

    AGM is still a lead acid battery.
