The best solution for this money.
Packaging has been opened. The battery cover is not held, it is assumed there is no screw. On the device, there is no indicator of the charging process - just switch.
Charge the phone and Samsung b2100 Sony Xperia Acro S. Charging the battery life of mobile devices comes from both the battery and on the AA-batteries.
11 mAh for $30 - that's a lot, lot cheaper than counterparts Li-Ion batteries. A great solution for long autonomous hikes, geocaching and Ingress game.
