I'm confused about which battery I need! The wiki link (above) indicates
"Specifically, it is two 1100 mAh LiIon cells in parallel, physically taped together."
However, the links on eBay lead to a square, flat-looking battery. Am I confusing models, batteries, or just confused in general? Maybe I should just open the machine and look? (I'm clumsy and worried about breaking it!)
Many thanks for replying!
