Battery Charger 101

As I mentioned in my last post, if you want to charge the new K16 through the accessory plug you will need a new charger dedicated to this bike. The older models will have to be connected directly to the battery to work.

Anyway I went out and got a new charger and it was still having problems. I would plug it in to the bike and the error light would come on not much else. After talking to BMW, what you are supposed to do is leave the key in the bike in the on position. Plug the charger into the accessory receptical and then plug in to the wall socket in that order. The charger will alternatively flash between red light and green light for about two minutes until it has successfully recognized the bikes charging program. When it has done so the charging level lights will quit flashing and one indicating the level of the bikes current charge will remain on continuously. Leave the key in the bike in the on position until you get a steady continuous light, then you can turn the key to the off position and the bike should start to charge. This charger is slow to say the least. The guys at the BMW shop on Vancouver Island were saying that the bike would have to sit with the charger on for 48 hours or more before the battery would go from low to fully charged. My K13 could charge up in a 1/4 that amount of time. Any way I hope this helps.

Re: Battery Charger 101


All I can say about that charger is to step away from it! It isn't worth the trouble.

It is way to easy to just hook it up directly to the battery. I have a short pigtail hanging on my battery and it doesn't even require raising the seat. It has a cap on the end and stays clean.

Way too easy!
Same here !! The dealer even installed it FREE when I bought the battery tender. The lead is ziptied to the left frame just above the left foot peg.

Re: Battery Charger 101

Dan, I agree with you . I connected a wire for my heated gear direct to the battery and charge thru it with my battery tender. Very easy.
