The battery's definitely going bad. I may have forgotten to keep it charged at some point, or maybe it's just the fact that it's old. (Obviously, all our GCW Zero batteries are old by now.)
Does anyone happen to know the maximum workable size (dimensions) and chemistry (LiFePO4 / NMC / other)?
I've been through a lot of posts, and there's very little to go on.
Also, any information about the connectors would help. I don't really know what sort of connector (if any) the battery uses or whether it's glued in place--anything like that.
Yes, I could find out some of this (probably not the chemistry) by opening mine, but I *have* read that it's relatively easy to damage, so I'd rather open the case exactly once if someone else has this info.
