I am thinking of purchasing some extra batteries just in case. My question is how do I keep them good? I mean, if they sit and are not touched or used for say, a year, will they still be ok? Or do they degrade regardless? I was guessing that if the battery sat without ever receiving a charge that it would stay good for a few years, as many of these types of batteries are stored in boxes for quite some time before they are purchased (thinking PDS's). Who is the battery expert? (IMG:https://gizmondoforums.com/forums/style_emoticons/default/smile.gif)

Lithium ion batteries basically start to lose capacity from the moment they are manufactured so generally it's best to wait before buying your next battery. You can improve things by keeping them cool and dry.
Put them in the fridge with about 40% charge. Check them every couple of months and recharge to 40% if necessary.

Wikipedia has quite a good write up here: http://en.wikipedia.org/wiki/Lithium_ion_battery

From the Wiki:

"The rechargable lithium-ion battery required nearly 20 years of development before it was safe enough to be used on a mass market level, and the first commercial version was created by Sony in 1991, following research by a team led by John B. Goodenough."


"Goodenough?"

Guess after 20 years of batteries exploding in your face they decided they were good enough. Haha!
