Storage:
To ensure that the battery maintains the capacity level, it is recommended that the battery and battery pack be stored at -20~35℃, low humidity, and no corrosive gas. Storage under high temperature or high humidity will cause battery leakage, rust, and capacity reduction. Long-term storage may reduce the capacity of the battery and battery pack. At least cycle charge and discharge once in a month.
caveat:
Reverse charging is not allowed, and the battery should be connected according to the polarity, not reversed.
Short circuit is not allowed, otherwise it will cause permanent damage.
The battery cannot be used under extreme conditions, such as extreme temperature, deep cycle, extreme overcharge and overdischarge. One overcharge or overdischarge will cause the battery to bulge, permanently damage and irreparably.
Please store the battery in a cool and dry place. If a large number of batteries are stored or shipped, the battery must be discharged to the storage voltage first(3.7V to 3.9V).
Do not directly solder the battery(Need to transfer nickel. If you don’t need to transfer nickel, please communicate with customer service).
If the battery has abnormal conditions such as noise, high temperature, liquid leakage, etc., please stop using it immediately.
Do not throw into fire or try to disassemble, the battery may burn or produce harmful substances.
It is not allowed to mix old batteries or half-used batteries with new batteries, otherwise over-discharge will occur.
Do not cut the outer casing and remove the outer tube of the battery.
It is not allowed to put the battery in water.
Precautions:
There must be someone at home when the battery is charging. If this regulation is violated, all the consequences shall be borne by the purchaser.
The battery should be charged before use. Use a dedicated balance charger to charge.
The battery should not be used in a sealed manner, and appropriate ventilation devices should be provided, otherwise the battery may generate hydrogen gas, which may cause an explosion if there is an ignition source.
Do not attempt to separate the battery pack or subject it to squeeze and collision, which may cause the battery to heat up and catch fire. The splashed alkaline electrolyte will damage the skin and eyes and will corrode clothing.
Keep the battery away from children. If it is swallowed, contact a doctor immediately.
When the battery is not in use, it should be removed from the device.
When the battery is hot, do not touch it until it cools down.
When the battery is in use, the device should be turned off when the energy is found to drop to avoid over-discharge.
When unplugging the battery pack, you should hold the battery pack terminal and not the cord.
After the battery is used, if the battery is hot, it can be placed in a ventilated place without direct sunlight before recharging.
BatteriesDIY is risky, and those who don’t understand should be cautious.
If you buy batteries, it means that you are familiar with the precautions of lithium batteries, and our company is not responsible for the consequences.
Friends who DIY assembling batteries by themselves, please note: we can only guarantee that the monomer is good, and can be returned if there is a problem; for problems after assembly or during assembly, we cannot guarantee the return, such as the protection board is connected to the wrong wire and burned and the battery is damaged , If the battery is damaged by the charger failure, and the battery is damaged by the assembly error, we cannot provide the return; if the battery is damaged, such as swollen, welded, etc., we do not provide return and exchange, the battery cell can only be unused Pass(The electrode is intact, without welding or damage, and the appearance is intact)Return and exchange is provided under the status, and 7 days test time is provided after the arrival of the goods. After this time, it means that there is no problem with the battery, and no return or exchange is provided.
