It is indeed an original battery, but does not meet the quality criteria SAMSUNG for the following reasons: The battery I received was down slightly from side to delivery. After 4 months of use in alternation with the original one, the battery discharges bought 3 times faster under the same conditions of use. Supposedly guaranteed 6 months, after contact with the seller, no response ... So enjoy it works as well and tell you that it is consumable at this price.
