Complicated. Where is this draining done? And I would guess there are hidden, surprising unintended consequences. And maybe a limit to how many drainages can be done.
and “....an hour behind the wheel each day, so resting a car battery for several hours isn’t out of the question.”
How can people remember to do that and have the energy and time to do that every day?
“I’d like to go to the club but I just started resting my lithium batteries in the EV so I’m stuck here.”
“Oh, yeah? Sounds like you’re lying. You’re seeing Emily again behind my back.”
“Where is this draining done?”
That was my first thought.
Down the kitchen sink? In your neighbor’s yard, maybe?
