The original battery in my CS was six years old and my battery monitor was taking ages to charge. Even after a long run. I'm too tight to pay the £600+ at an OPC so looked at the options.

Can't fault them or the battery. especially with a 5 year warranty. The only problem is that I have to remember to turn off the stop-start now.
