I’m not sure of the intricacies but this change was made to avoid the dead 12v situations. I imagine now as the main battery can now recharge the lithium one easily it keeps it topped up somehow to avoid this happening.

I left my Tesla for nearly 3 week holiday not plugged in and it was fine when i came back.

No the old cars do have the old 12v one in still. They obviously learned its a bad idea. Newer models don’t have it and have a lithium rechargeable instead.

They used to but not anymore, they now have a rechargeable lithium 16V battery.

Orphan Black.

Intriguing show that entertained throughout, backed by one of the greatest acting performances I’ve ever seen in tv by Tatiana Maslany.
