Note: Before you buy this Product Please Be Sure this RXV is the type of your Cart. Unplug The Charger. *If it hasn’t automatically shutoff in 14 hours: *The charger is designed to turn off when the voltage of the battery pack reaches a certain level. I have found that some battery packs don’t always reach the required trigger voltage and the charger remains on in a trickle charge mode. *If this happens, unplug the charger from the wall outlet, your cart should be fully charged. Most of the times after the charger has completed a few charge cycles the charger will begin to operate automatically. .
