battery instructions

     please be sure to charge the battery before using it.

 lwhen charging, keep away from flammable items. overcharging may lead to battery explosion.

 lif a broken battery has been generated, please deal with it in green immediately and cannot be used again.

 lthe connection of positive and negative poles will lead to the danger of short circuit and explosion of the battery.

 lbattery damage and damage caused by failure to follow the instructions shall be borne by the user.

 lthe battery damage caused by human overcharging and overdischarging cannot be returned or exchanged.

 ldo not charge and discharge without care, which is easy to occuroutside

 the purchase of batteries is deemed to have agreed with the above views. due to the above circumstances or violation of safe operation, the user shall bear the responsibility.

   【battery usage warning]]

 lithium battery pack single grain cell voltage cannot be reduced2.75vbelow ◇

 otherwise, the battery will be permanently damaged or even scrapped.                    4.20v----100%

                                                                                                           3.95v----75%

 3.85v----50%

 3.73v----25%

 3.50v----5%

 2.75v----0%

 the charging current is less than or equal to the battery capacity5%:

① charging time (hours) = battery capacity (mah )x1.6÷ charging current (ma );

charging current greater than battery capacity5%, less than or equal10%:

② charging time (hours) = battery capacity (mah )x1.5÷ charging current (ma );

charging current greater than battery capacity10%, less than or equal15%:

③ charging time (hours) = battery capacity (mah )x1.3÷ charging current (ma );

charging current greater than battery capacity15%, less than or equal20%:

④ charging time (hours) = battery capacity (mah )x1.2÷ charging current (ma );

charging current greater than battery capacity20%:

⑤ charging time (hours) = battery capacity (mah )x1.1÷ charging current (ma );

       [tips]]

 ldo not use nickel cadmium ( nicd), ni-mh (nimh) or other types of battery charger for lithium (li-ion) battery charging. please useli-ionspecial charger for charging.

 ldo not charge without looking.

 ldo not overcharge (the voltage of each grain cell fully charged does not exceed4.25v).

 lwhen charging, please pay attention to the heat resistance and high temperature resistance of the charging desktop or platform.

 lat any time, the battery cannot be overheated cell. cell temperature up60after ℃, there will be potential safety hazards, even burning.

 lwhen charging, the battery cannot be accessed or placed directly on flammable articles such as paper, plastic, carpet, ethylene, leather and wood.,or directly put it in the model car or car for charging.

 ldo not put it over (the voltage of cell per grain is not lower2.75v), it is easy to damage the battery after being released, such as bulging.

 ldo not put the battery close to the liquid, and do not store the battery in a damp place.

 ldo not close the battery to fire sources such as open flame or heater.

 lplease place the battery out of reach of children.

 lif a collision occurs during use, remove the battery. carefully check whether the battery and connector are normal, just in case. (note: the battery may be hot at high temperature!)

 ldo not splash electrolyte on eyes or skin,if accidentally splashed,please wash with clean water immediately, and if serious, please seek medical treatment immediately. do not disassemble the battery arbitrarily or change the wiring.

 lplease carefully check the battery voltage and power before charging or using.

 ldo not short circuit (positive and negative poles are connected in reverse).

 ldo not directly contact the battery with leakage.

 lplease0~45charge in ℃ temperature.

 lfor long-term unused batteries, please ensure3perform a charge/discharge activation within a month to maintain stability
