I bought two of the 2000 mAh Galilio batteries off of eBay and when you pull the label off they are plainly marked 1000 mAh. They work fine, but I just want to warn people about this. This seems to be a common problem people are having. I ordered a generic 3600 mAh battery with battery door on Amazon. If it works out better than the Galilio's I will post it here.
