“Very useful.Auto /manual settings fast charge and easy to use diagnostics.Great price and minimum 2 year warranty and next day delivery.Also fact that guarantee extendible free to 5 years by registration.Cannot fault it.”
“Seems to be a good battery charger/tester. My old trickle charger wouldn't charge a totally flat AGM stop/start type battery so I bought this one to try. Took 3 days from totally flat to full charge but did the trick. Great for testing the battery too, which is now holding 90% charge after 4 days. Might shop around a bit next time though as I found out later that it's cheaper in Halfords than direct from Ring.”
