I put my bike on BMW's CANbus charger if I am not going to ride for a few days. Normally it will charge for a bit and then go into maintenance mode. I recently noticed it never goes out of charging mode. So this is what I know:
I have keyless ride and turned off, the bike draws about 55ma.
When hooked up to the charger, the display eventually goes to 14.4v, charging at 0.4amp and 96% charged, but no further.
Voltage at the battery is 13.06v after being on the charger overnight.
So why won't the charger kick into maintenance mode anymore? Is it the battery or the charger or the bike?
I'm charging it now off the bike to see if it gets to 100%.
