Storage： The battery should be removed from the equipments if not been used in a long term, and kept at a comparatively low temperature (0～20 ℃) and in dry environment. Avoid to mix up with other electric materials (metal, etc.). Charging to 50% capacity before deposit is preferred. And charge and discharge in small current before use again.
Charge： Charge under small current if possible, especially when the battery is used for the first time. Intelligent inspecting and protecting function is required on the big current charger, but it still affects the battery life time. Avoid over charge since it could lead to the damage (over-heating, leakage and explosion) of the battery.Charging under room temperature is preferred, high temperature lowers the charge efficiency.
Discharge： Cut off the circuit immediately when the battery discharges to a low voltage status which can not support the efficient work. The lowest working voltage is 0.8 V for NiMH and NiCd battery, Li-ion battery is protected by the protector, over discharge can do harm to the battery.
Take care of the battery： When the battery is under charging/discharging, pay attention to the change on battery surface, temepature and charge/discharge time. Stop using the battery if there is any unusual.
Avoid mixing： When two or more batteries are put in the same pack, make sure their consistency, like the same brand, the same charge/discharge history and the same coulomb. The huge difference between different batteries will lead to some batteries are over charged while some are over discharged, it can even cause accident.
Capability recovery： Run one or two complete charges and discharges every two or three weeks.
Special attention： Avoid falling off, impacting, piercing, short circuit, waterlogging and drenching. Take away from fire and children.
Abandoned batteries： The batteries which are out of date should be concentrated and given to related institutions. They can not be thrown at will since they will cause security accident and environmental pollution.
