i've had a store of [originally 24] lithium 3 volt desktop batteries in the
freezer for about two years. the most recent one i pulled one from that stock
was about three months ago, to replace a dead one in a friend's box, and it
appears to be as fresh as the first one i put in one of my own machines back
when i got them. so, although i'm not talking about laptop batteries, in my
experience, the theory holds.
