I bought this brand new battery for a used Unlocked Motorola Razor. The phone was going to be a gift for a relative overseas. The battery is DOA. I charged it first thinking the battery was drained. Four hours later the phone wouldn't power up. I put in the old battery and voila everything is working. I just wasted $5 and four hours of agony. Why would a seller bother to ship a battery that is dead without testing it. Don't buy from this seller folks.
