a lithuim battery can be charged up to a max of 4.2vdc. it is to be plugged in the cigarette lighter for 2-3hrs. if you forget to unplug it, no harm done. oopppsss, because of this reply, mawawalan ng sales ang mga battery stores. cost of parts p100-p200. cheap, no?
are all lithium batteries rechargeable? or only those marked "rechargeable" ?
