I bought a backup battery for my Droid. It was on Amazon for around $30.00. It was advertised as a Motorola BP6X battery, but it is not. It is a bootleg,when you put it into your phone a question mark(?) shows up on the battery icon. It wont charge up at all. It also has a bigger Hologram sticker than my original, along with smaller battery leeds indicating BOOTLEG.. Beware Buy directly from Motorola...
