Have decided to use this battery, because I do not think that the "original Samsung batteries" offered on the Internet for less than 10, are really not plagiarism. Then rather just a replica, which is certainly more honest. The Polar Cell Battery came with 70% hydrochloric charge and could be inserted problem and recharge. The battery discharges not faster than the original at several hours daily use. Conclusion: would recommend this battery. After 1 month, I am still very satisfied with the battery.
