Recharge in 2 hours
The standard battery is of the NiMh type, which means that the battery does not suffer from “memory effects”. The recharging time is normally around 2 hours. The battery typically lasts for about 4 hours during medium work. The recharger unit is microprocessor-controlled and will sense the battery charge and temperature for best recharging method.
It is impossible to give advice as to the life span of a battery or when a battery will lose its usefulness. There are simply too many variables to give such advice, such as mode of use, storage, work load, number of recharges, frequency of recharges, normal chemical changes within the battery cells, and many more.
The warranty on a battery covers manufacturing faults of components and workmanship; it does not cover the actual performance or output of the battery over time.
