I received my battery, and it is at least a MOTOROLA battery, but not a BT50- it's a BT51. The code off the back was partially rubbed off. I charged the battery for a full 24 hours before using the phone, and it would not get to a fully charged point. My battery meter would only read 4 of 6 complete. So for the price- it's fine as my old battery would give me 20 minutes of time even in standby mode before shutting off- but there is no way to convince me this battery was NEW as indicated in the extended description. Shipping time was fine, and shipping was either nominal or free.
