Review on IEIK 12V 8A 24V 4A Automotive Smart Battery Charger Maintainer for Car, Truck, Boat, Motorcycle, Lawn Mower, SUV, RV, ATV & More - Yellow by Adam Davidson

I have bought several of these and prefer them to actually similar models from Harbor Tool, Walmart and other companies before. Also, for a reasonable price, I'm thinking of permanently mounting one of these on each battery in our RV so that when using "shore power" we don't have to worry about the batteries staying charged. The "Recovery" feature is also really good when run every few weeks to lower the sulfate levels on the battery plates which should SIGNIFICANTLY increase battery life.
