I'm somewhat familiar with what lead acid and NiCd's like, but what = about lithium ion? My laptop has a litium ion battery, and I'm = wondering, should i recharge it once it's at a low percentage, or is it = best to keep it at a high state whenever possible? Should I = periodically discharge it even when I don't really need it, or is it = fine during periods of no use? Does it have any special requirements at = all? I've seen very little information on lithium ion batteries on the = net, I'm hoping someone in here knows a bit about the chemistry of the = battery who can enlighten me. --Nick -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
