Hi, I'm no expert on Li-Ion batteries, but i read/heard once that you'd better don't store them (for lang time) epmty. So yes, keep them filled when you put them away. And some own (notebook) experience is that they do behave like ordinary nicad's that means that the voltage drop is very rapidly when they're almoste empty. Regards, Aart.

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.
