although I bought one early in the month it still hasn't arrived, so I'm going to toss a question to those who own one - what's the capacity of the batter in mAh? I wonder if it's possible to buy a larger capacity battery to get more life out of the system. Is there a model number or anything?

Does anyone own a SNES Powerpak? I'm wondering if the use of a flashcart will diminish the battery faster than a regular cartridge would.
