Purchased this battery for my Galaxy SII, which I use to keep phone on as standby in the car all day. This was the only place that sold a replacement battery, and its been working great. Holds charge well even with constant use, though I'm no longer using it heavily at all. Highly recommend if needed.
Output:
Good Review
