The backup is only used when the main is totally depleted or removed, and then all it does is preserve the RAM for you. It is NOT rechargeable.

A lot of us saw that flucation you mentioned. If you soft reset, it will pop back up to 100%. It turns out the circuit that senses the battery is very sensitive. A .01v drop will cause the battery to drop 10-20%. That kind of drop comes from just temperature changes.

I replaced my backup battery with a new one ($3) and it has never reported less than 100% since.
