Thanks, I'll send you an e-mail about the charger. By the way, the BMW gel battery is far and away the best battery I have ever had. I have really abused this thing and it is still working fine. In the latest episode, I left my radar detector on, which I unfortunately have done a couple times in the past, and after a couple of days it drained the battery completely. When I have time, I need to wire the radar detector outlet to come on with the ignition. With the BMW charger, I have found that it would not charge if the battery was all the way down. I've had to put on my trusty Sears charger on 12V 2amp setting and charge it a few minutes and then put the BMW charger on and it would complete the charging. Since my BMW charger was not working this time, I left the Sears charger on longer and then, since I was in a hurry, roll started the bike. After riding it around for a while, it came up to full charge and has been fine since.
