I'm sure the battery I received is fine; however, the service was not. All BMWs manufactured since 2002 require registering a new battery with the engine's control module (DME) to prevent the DME from overcharging the new battery (which doesn't require as much charging as an older one). 1-800-Battery techs do not have the equipment to do this even though they clearly advertise full and complete BMW battery installations with no warning that they do not complete this step. So, after paying them to install the batter, I then had to go to the dealer and PAY MORE to have them reprogram the car. 1-800-Battery acknowledged that they didn't complete the instllation and that they provided no warning that this would not happen and, so far, has refused to offer a partial refund.
