Review on 🔌 TecMate TM-341DUAL OptiMate 4DUAL 1 Amp Weatherproof Desulfator Charger/Maintainer by Jeremy May

I currently have 3 of these chargers. I use one at home, one in the country and one I keep in my truck. I have a fast connection to quads, lawn mowers and vehicles. I connect this to batteries in the winter to conserve battery power. I have had no issues with the batteries overcharging or losing effectiveness when using this charger. I don't have any empirical data, but my batteries have performed better over the past two years (in cold winters) after using these chargers.
