4.1 Transport & Store
The battery need to be charged every 6 months if out of use; No
fall down, no pile up over 6 layers, and keep face up.
Warning
* Battery must be far away from heat source, high voltage, and no
exposed in sunshine for long time.
* Never throw the battery into water or fire;
* Never reverse two electrodes when use the battery;
* Never connect the positive and negative of battery with metal;
* Never knock, throw or trample the battery;
* Never disassemble the battery without manufacturer's permission
and guidance.
Never use mixed with other type of battery;
Tips
* Keep the battery against high temperature. Otherwise it will
cause battery heat, get into fire or lose some function and reduce
the life.
* When battery run out of power, please charge your battery timely
(≤15day).
* Please use the matched or suggested charger for this battery.
* If battery emit peculiar smell, heating, distortion or appear any
abnormity, please stop using.
* If the battery leaks and get into the eyes or skin, do not wipe,
instead, rinse it with clean water and see doctor immediately.
* Please far away from children or pets.
