Cool! It has never actually been used for that long at a single stretch. I would then recharge it as needed. I am using the NiMH that came with it, so I try to keep it charged as much as possible.

By the way (Battery 101 question), what is the best way to extend the lifespan of an NiMH? Let it drain fully? Never let it drain fully? Always try to keep it fully charged?

Meanwhile, I will check out the firmware update. I have not been having any problems, but I do want to keep up to date. Thanks!!!
