OK, post another update when you unbag it again. (You have to bag it for some offseasons?) I think the temperature probably had something to do with it, especially since it was affecting CD players, though I've never heard of them being affected by temps just above freezing.

True. I've had this experience with nicad cordless tool batteries. They appear to take a full charge(measure at full voltage), and may even hold their charge for a while, but as soon as they're used to drive a motor...almost instantly unusably weak.
