Samsung EB-L1G6LLUCSTD battery pack, Li-Ion, 2100 mAh, compatible with Galaxy S3 / S3 LTE (frustration free packaging) (Accessories)
I just actually decided to order the battery due to a recommendation from friends, but unfortunately was not so lucky with the quality, as my acquaintances. The battery, which I ordered, has been discharged during the phone on the power supply go O_O
