Why are you so worried about this battery?
It should not be a big deal to recover if you take some basic steps to have backup (ability to detach negative terminal, emergency jumper battery, & 12V hidden behind tow hook cover). Haven’t tried it though!
Also it often (not always) fails gracefully.
And replacements are cheap. Initially I worried about it on road trips but it seems you can just disconnect the 12V and then you *might* be fine. YMMV.
I do wish that someone with one of the new batteries would measure the vampire drain with the new setup and using the known battery parameters (capacity, discharge curve, etc.) determine average sleep power.
no need, cars been patched. If 12V goes down the car continues to work normally but just doesnt go to sleep.
