* Charge times vary depending on battery capacity and specific charger. Our chargers provide intelligent charging. A solid green light indicates the battery has reached an optimum charge level - approximately 85-95%. The charger then continues to charge the battery to a max charge level at a slower rate. This reduction in charge rate helps maximize the life of the battery.

Capacity (Wh) = Voltage (V) x Ampere hours (Ah)

Batteries are best measured in Watt hours (Wh) which is the combination of Volt (V) and Ampere hours (Ah). For example, our 40V MAX* 4.0 Ah battery provides more capacity than a 56V 2.0 Ah battery.
