Instructions&Storage
Precautions And Safety Instructions Of Lithium Battery Pack
When the voltage between the two electrodes is over 36V, the safe voltage of human beings, you should not touch them with your body.
· Do not immerse the battery pack in water or seawater, and keep the battery pack in a cool dry surrounding if it stands by.
· Do not expose in the sun.
· Do not expose in the rain or snow
· Does not use or leave the battery pack near a heat source as fire or heater.
· Use the battery pack charger specifically for that purpose when recharging.
· Do not reverse the position and negative terminals.
· Do not connect the battery pack electrodes to an electrical outlet.
· Do not discard the battery pack in fire or a heater.
· Do not short-circuit the battery pack by directly connecting the positive and negative terminals with metal objects.
· Do not transport or store the battery pack together with metal objects such as hairpins, necklaces, etc.
· Do not strike, trample or throw the battery pack.
· Do not directly solder the battery pack and pierce the battery pack with a nail or other sharp objects.
· Do not use or leave the battery pack at high temperature (for example, at strong direct sunlight or in a vehicle in extremely hot weather). Otherwise, it can overheat or fire or its performance will be degenerate and its service life will be decreased.
· Do not use the battery pack in a location where static electricity and magnetic field is great, otherwise, the safety devices may be damaged, causing hidden trouble of safety.
· If the battery pack leaks and the electrolyte gets into the eyes, do not rub the eyes, instead, rinse the eyes with clean water, and immediately seek medical attention. Otherwise, it may injure eyes.
· If the battery pack gives off strange odor, generates heat, becomes discolored or deformed, or in any way appear abnormal during use, recharging or storage, immediately remove it from the device or battery pack charger and stop using it.
· In case the battery pack terminals are dirty, clean the terminals with a dry cloth before use. Otherwise poor performance may occur due to the poor connection with the instrument.
· Be aware discarded batteries may cause fire or explosion; tape the battery pack terminals to insulate them.
· Do not disassemble the battery pack , there may be a danger disassembling the battery pack.
· Do not expose to temperature above 60℃ or heater.
· Do not use the battery pack connected in series or parallel.
· Storage in a dry and ventilated room, keep away from other dangerous materials.
· Charging battery pack should be monitored by professional person. Charging process should ensure the connection of the plug and socket, the normally charge device, and all the connections of battery pack in good condition. If appears unusual things, charge must be done after restoring.
Storage Of Lithium Battery Pack
1.The battery pack shall be storied within -10℃~45℃ range environmental condition.
2.If the battery pack has to be storied for a long time (Over 1 months),the environmental condition should be:
Temperature: 23±5℃
Humidity: 65±20%RH
3.The capacity is 80-90% of nominal capacity.
4.When storing battery packs for more than 6 months, charge at least once every 6 months to prevent leakage and deterioration in performance due to self-discharging.
