** This charger is compatible with pre-2007 Club Car golf carts only. Updated version coming soon. ** What a fantastic charger! Its quite powerful and simple to use. You can connect this, turn it on and it will start charging immediately. After that you can leave it connected forever to your battery with no danger of overcharging. This will not burn your battery. A sophisticated charging computer constantly monitors the battery and will charge just as much as needed to maintain your battery at full charge. Take a look at the features below and you'll see this is much more than a simple battery maintainer, its a smart charger! Green LED indicates AC POWER ON, Yellow LED indicates battery is charging, Yellow LED off indicates that charging has completed and the charger has entered float mode. This charger has a front panel switch selectable for either "Flooded" (normal lead acid batteries that have caps for checking liquid level) or the AGM type (Sealed) batteries. Due to the charger's maintenance mode the formation of sulfates on the battery plates is greatly reduced.
