This is the 3rd "OEM" battery I bought via Amazon Marketplace -- as with the others, it was terrible. I ordered form the OEM shop a BR50. They sent a BR56 which is supposed to be even better with 3 hours talk time. It did not last 30 minutes after a complete overnight charge. Nowhere as long as the battery I am trying to replace which lasts over an hour instead of the original 2 1/2 hours.
