Am wondering if anyone has changed their batteries. I understand that the G battery is about 1150mAh. I saw one in the market going for 2200mAh. Was wondering if I should go for it and change out. I know there are alot of battery boosters in the market but it would be really ridiculous to carry a few around (since most of them are about 1100mAh) Also, once I change, the warranty becomes void. Any suggestions or comments are welcomed. Would you change out?
