Anker® 2 x 1600mAh Li-ion Battery for HTC Desire Z, Desire S, Incredible 2, Incredible S, Salsa, EVO Design 4G, + free USB Travel Charger (Electronics)
For the price of around 15E I am satisfied for Top! 2! Batteries! MIT! Charger. War never with an empty battery on the go. If one went empty, you take the other and invites both again overnight, super thing!
