DIRT DEVIL ACCUCHARGE STICKVAC 15.6V

The AccuCharge system protects batteries from degradation, meaning a longer battery life and effective runtime throughout its lifetime. And, it charges twice as fast, so you won’t have to wait as long in between uses. Plus, special AccuCharge Circuitry constantly monitors the unit until the charge voltage is reached and then reduces power to a trickle charge to complete and maintain the charge. This results in a reduction of energy consumption by 70%
