Lithium-ion batteries are much less subject to drain over time if they're not being used.
The Model S uses a 12V lead-acid battery though(and subject to the drain and upkeep you mentioned), so I'm not sure why they author has been waiting on this bespoke, single manufacturer one. Unless maybe the connectors are non-standard?
- greglindahl 10y agoThe little 12V battery is a standard car battery form factor and connector. Most Teslas have a marine battery instead of a standard car battery, but that's not hard to find.
- LeifCarrotson 10y agoYep, after a little research, it's a BCI 33 series. You'll find a few (if designed for starting current, not deep cycling) in any parts shop.
- frandroid 10y agoWait. A Tesla car is literally a rolling lithium-ion battery pack, and yet it also needs a lead-acid battery too?
- mikeash 10y agoYes. You want to isolate the main battery pack in a crash (400V applied to emergency workers is a bad idea) but you still want to be able to power some basic systems.
- Corrado 10y agoMy understanding was that it had to be a Tesla battery or they might not re-certify the car.
