Does anyone use a solar battery charger? I'm not familiar with the BMW electrics and I understand it needs a special optimate to charge?
 
That’ll be the canbus. If you must use a charger just get a optimate or such with a fly lead to the battery. I’d think you could do the same with a solar charger. In my experience I’ve never needed a external charger even while parked for 3 weeks. Personally I feel that those chargers do more harm than good. JJH
 
If you connect directly to the battery then the BMW electronics will not affect the charging. As JJH states, a poor quality charger can have a detrimental effect on the battery (or electronics if the battery remains connected to the bike).

Like JJH, I have left a bike with a modern battery, usually an AGM type, for several weeks. Unless there is a drain of some sort like an alarm system then these batteries do not discharge very quickly compared to older, wet batteries.

Like JJH, I would not use a charger unless it is a device approved to the relevant CE regulations from a recognised maker such as Optimate, CTek etc.
 
so optimate is ok then ?
every bike i have had/have has them connected ?
 
As I understand it the canbus system needs a specific charger, Nippy Normans have them for £60. I'm assuming I can just disconnect the battery and charge it normally with any charger?

Where any charger is one designed for AGM batteries, not the one grandad used on his Morris Oxford.
