Serious question:

If lead-acid batteries aren't good for deep-cycle use, then why do most UPSes use them? Do they use a special lead-acid design that's actually ok with deep discharges?

(I'm trying to figure out how to put together a battery-driven portable power-system, at least in theory.)


@woozle This is the field I work in (off grid). I have many thoughts on this. Sometime when I am not on a tiny touch keyboard. DM me pls and I'll get back to you when I'm back home

@jond @woozle oh could that happen here in public? I am interested in this too.
