I have no electrics in the garage I park my RS and would like to disconnect the battery for the winter months. |

Zitat von Mick Austin im Beitrag #1 yes - the clock, although it will reset if you have a BMW Navigator and you have it configured to automatically readjust otherwise, it will be fine you may change your mind when you see what a faff it is to extract the battery on the RS. Can you run an extension lead to the garage once a month to put the battery on charge for a day? My experience with these AGM batteries is that they stay charged for 2-3 months and will only need an occasional top up if left on the bike from now until Easter. |

Thank you Wessie. The garage is about 200 meters from where I live. I know it is a bit of a faff to remove. But would like to have the battery connected to a trickle charger (Optimiser) to keep it in good condition. Do you know if I will have to reset the throttle positioning sensor when reconnecting? |

Zitat von Mick Austin im Beitrag #3 I don't think so. I remember there was a procedure for the R1150GS but not seen anything mentioned about more recent bikes. The RS control systems will be all digital. A lot of the electronics on the R1150GS were based on analogue controls - I used to watch my independent mechanic set up the fuel injection using a vacuum gauge and voltmeter to ensure everything was balanced on each cylinder. Nowadays, it will all auto-adjust as part of the fly by wire system. |

I have no idea about their effectiveness, but would this be a suitable application for a solar-powered trickle charger?

Zitat von DJBee im Beitrag #7 I have not used a solar charger but I know people who do use them successfully on bicycles, cars, motorbikes, campervans, caravans and garden machinery. If there is no load on the battery like an alarm then they might keep a battery topped up. A southerly aspect is better. If the shed is in the shade of trees or buildings then it won't work. The OP lives in the Black Country but I believe the pollution that gave the area its name should not be a problem nowadays. |

I have a Optimate 4 Can bus connected to my bike. It is stored for winter and I am leaving a few times during winter and I intend to disconnect the charger when I am away for peace of mind and insurances coverage. Some people on other forums tell me not to disconnect because it will affect the Can bus system. I don't understand why it would affect . If I disconnect and reconnect, it will restart it's work. Is there a technical reason that I am missing here ???

Zitat von albrown im Beitrag #9 I had my battery off the bike for two weeks before fitting a replacement without any problems. I am not a fan of prolonged float charging as I believe it dries out the electrolyte. Also some cheap solar chargers have poor regulation leading to possible overcharge. Might not be a problem on a big vehicle battery but not so for a 12ah gel motorcycle unit. I prefer periodic charging after discharging the battery on a small load. Bit of a faff but keeps the chemicals active. Alan |

Zitat von Alda im Beitrag #10Zitat von albrown im Beitrag #9 same here - treat the battery the same as it gets in service i.e. a period of charging when the engine is running then sit idle for long periods. Simulate this with a charger over winter. |

Zitat von albrown im Beitrag #9 "some people on the internet" do not have a clue just think of your charger as simulating the alternator - this charges the bike whilst you are riding it and then switches off when the engine stops. The CANBUS is not harmed. |

the OP may find one of these useful - connect directly to the battery (or remote posts in the case of the RS) and it will tell you if the battery needs a charge |

Apologies for being a novice on the BMW side of things (I have only owned one since August). |

Zitat von BizzyBee im Beitrag #14 I use a Optimate on both of our RSs and leave the battery in the bike over the winter. I have a harness connected to the battery I use for charging, heated gear and tire pump.
