I've had a few experiences both with my own bike and with friend's bikes where the battery simply dies without warning. Happened again over this bank holiday weekend when a few of us were touring around the North Yorskshire Moors. The bike started perfectly normally in the morning, followed by a few starts and stops during the day, and then suddenly nothing. Not a flicker of life in the battery. It was a Yuasa, around 5 years old, and regularly used and kept fully charged.
So my question is, is there any way of knowing when these so called 'maintenance free' batteries are on their way out? Or do we just have to just take pot luck and hope the RAC membership hasn't run out?
Cheers guys
Riggers.
