RING SMART CHARGER

Ring Automotive’s new slimline, weatherproof 6A charger is claimed to be suitable for 12V batteries for vehicles of up to 3.5 litres, and is compatible with lead-acid, gel, calcium, EFB, AGM and lithium cells. Its maker claims that it’s capable of charging twice as fast as a standard charger, it has a cut-out to prevent overcharging, plus it can detect battery condition and desulphate tired units. We tested it on an old, flat battery, and it was simple to use: connect, plug in and the unit picks the best charge cycle. It revived our battery with ease and speed. But plenty of chargers can do that; the impressive thing about the £65 RSC706 is its small size and light weight (166x104x37mm; 0.744kg). AC ringautomotive.com
