Led indicator light issue.
Worked fine on charging but led indicator light would turn red after several hours of maintenance charging. So had no way of knowing if this was still operating. The manual states if the light turns red the poles are not connected properly. This was being used to maintenance charge a brand new 12volt motorcycle battery. I checked it on my van battery after consulting "Ring" technical. It worked fine on that so took my battery back to halfords who analised it and declared it a good battery.
