I plan to keep SORN a bike over the winter, but don't have electricity in the garage that i keep it. So my intention is to start the engine every 2-3 weeks and leave it idle for a few minutes. Would that keep the battery live because it is a bit of PITA to try to take it out ?
Thank you very much for your replies. I particularly like the idea of a booster. My battery already has leads so while I can't easily remove it I should be able to charge with a portable one. I just dont want to mess about trying to unscrew panels and disconnect leads etc..
