OEM Motorola BT91 for Motorola Rival A455, Motorola KRZR K1m, Motorola Q, Motorola Q9c, Motorola Q9

• Extended Battery

We purchased two new BT91 batteries for our Verizon Motorola W755 cell phones. They work great and our phones are able to go for many days without recharging. Thanks for providing us with these batteries Amazon! But don't forget that you will need the thicker battery cover that goes with this thicker battery. The other reviewer who complained about this battery and only gave it one star did not realize this when he ordered the thicker battery and failed to order the thicker battery cover for the phone.

I own a Motorola Rival A455. Its normal battery is a BT50. This battery will power the phone but is far too large to fit in the casing. It's about twice as thick. So unless you want an open back phone... No. It's really NOT compatible with the Rival.

I've had this battery less than a week and it won't hold a charge longer than a few hours. Maybe its my phone but I doubt it.

The item arrived very promptly in what looked like original packaging. The date on the rear of the packaging indicated 12/10/10. I don't know if that was the date of manufacture or sale expiration date. In any case, the battery lasts longer than my previous battery but not as long as the previous battery did when new. My phone usage (Motorola W755) is actually about half now of what it was when I originally got the phone. So, that was the only disappointing feature. I expected longer battery life.
