AT&T Cingular T-Mobile Motorola Razr V3 Silver GSM 1300 MaH 3.7v Li-Ion Lithium Extended Battery with Extended Battery Cover COVER (NOT Compatible with V3c, V3i, V3m)

REVIEWS:
1) Nice battery life extension though a little cheap looking.: The battery is great and does extend the charge life of the phone admirably if you can put up with the extra bulk (though probably not as much as you"d expect). Please note that the new battery door is plastic and not aluminum like the rest of the phone. So it looks a little cheap. This wasn"t a problem for me since I put my phone in a case anyway which covers the door.
