  4. Battery usage specification


    4.1 When the battery is used alone, it can be used directly.

    4.2 When the battery needs to be used in parallel or in series, each battery shall be fully charged according to the standard charging method before parallel or in series.

    4.3 The maximum series number of batteries shall not exceed two, and the parallel number shall not exceed four.

  5. Transport & Store


    When long-time storage, the battery SOC is 30% ~ 50% , if high-SOC storage will accelerate the battery capacity degradation.

    The battery need to be charged every 6 months if out of use

    No fall down, no pile up over 10 layers, and keep face up.

  6. Warning & Tips.

    Please read and follow the handling instructions before use. Improper use may cause heat, fire,rupture, damage or capacity deterioration of the battery. TOPAK POWER TECHNOLOGY CO., LTD. Describes is not responsible for any accidents caused by the usage without following our handling instructions.

    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;

    Attention

    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.
