5.Operating Instruction
Before using the batteries, carefully read the service manual and the specification of the batteries.
Please use the batteries in a normal environment, charge temperature is 0℃~45℃, discharge temperature -20℃~60℃
and the relative humidity is 65%±20%.
During their use, the batteries should be kept away from heat sources and high voltages, children should not be allowed
to play with them, and they should not be knocked violently.
In no circumstance should the positive and negative poles of the battery be short circuited. Do not disassemble or
assemble the batteries yourself and do not place the batteries in a damp place in order to avoid danger.
When the batteries are not to be used for a long time, please store them safely so that they will stay in a half-charged
state. Please wrap the batteries with non-conductive materials in order that metallic materials will not contact the
batteries directly, which may result in damage to the batteries. Keep the batteries in a cool and dry place.
Please dispose of the used batteries properly. Do not throw them in fire orwater.
If the battery is to be used in other devices, please consult with the supplier about the degree of perfection of its
protective function, Do not make arbitrary decisions to use battery in other devices.
6.Cautions
emperature range during charging
The recommended temperature range for battery charging is between 0℃ and 45℃. Charging of the
batteries out of that temperature range will cause the performance of the batteries to decrease and their
life to shorten.
Consultation
When purchasing the batteries, be careful to remember the way to stay in contact with the seller so that
you can contact the seller and have consultation with it when needed.
Warranty period
The manufacturer will not replace the battery free of charge even in the warranty period if the problem
with the battery results from misuse rather than bad quality.
Safety use guaranteed
If the battery is to be used in other devices, please consult with the supplier about the degree of
perfection of its protective function. You should at least have a clear knowledge of such issues as the
heavy current, fast charging and special application of the battery
