Small aside here: Li-ion tech is a major pain in my ass. Storing them discharged damages them. Storing them charged damages them. Keeping them topped off damages them. Fully discharging them damages them but your battery might have a protection circuit so don't worry about it. But it might not so worry about it. You've apparently got to store them half-charged for optimal lifetime but there is a lot of wrong information out there. I think I want to power my devices with disposables, thanks :-)
