Review on Battery Tender 3 Amp Car Battery Charger: Automotive Charger and Maintainer for Cars, SUVs, and Trucks - 6V/12V, 3 Amp Charger by Giovanni Bedjohn

Look around and you'll come to the same conclusion that this device offers more bang for your buck than any other battery conditioner/charger. 6 volts / 12 volts. The 3A output is enough to charge discharged batteries. 33 hour charge cycle limiter. reverse polarity protection. The device has two screw holes for attachment. The kit includes terminal blocks with fuse protection and other permanent ring terminals. The battery tender jr is suitable for small batteries such as lawn mowers, motorcycles, jet skis, but with only 8 tenths of an ampere rating, the jr can be overwhelmed by a dead car battery. 3 amps is ideal for overnight charging rather than draining a high amp battery for a shorter period of time. Agm lead acid batteries and gel cells are now extremely expensive. I have yet to change the battery of a car, boat, motorcycle or tractor that I have connected to the battery, I'm sure of it. I highly recommend this particular product. I am not affiliated with this product, any product or seller.
