Review on KONNWEI KW510 12V 5-Amp Smart Charger with Car Battery Tester - 3 in 1 Automotive Pulse Repair Maintainer, Trickle Charger Battery Desulfator with Temperature Compensation by Fred Meeks

This item is amazing and easy to use on many levels. I haven't used the battery repair feature yet, but I'm sure it will be as easy as the charge and recharge features. I especially like the internal fan that cools the charger when it's running for a long time. The test functions are also very quick to determine what might be wrong with your battery if you have a problem. The size of the device is true to size, not too big, easy to handle. The handles on the terminal are solid and don't pop out of the terminals like my old charger sometimes did. I would buy this item again. The charger was a fast charger, faster than expected, great performance!
