By default, customers who purchase this cell are familiar with lithium battery knowledge. If you do not know the correct lithium battery

use method, please purchase with caution. When using, strictly observe the parameters calibrated in the battery specification, overcharge and overdischarge.

Or if the battery performance is seriously damaged or even exploded due to improper use of soldering iron welding, our store will not accept it.

Take any responsibility.

2. Cell of our store is the actual capacity mark, and all products are.

3. Battery capacity test is based on the battery capacity separator as the standard, using mobile phone charging method and resistance discharge method

the measured capacity cannot be used as the capacity Test standard. The measurement of internal resistance, voltage and capacity can be straight when leaving the factory.

Please rest assured to buy it.

4. Each batch of shipment has been tested by professionals for over-voltage internal resistance, appearance and other problems. We can only guarantee that the monomer is good. No return or exchange will be provided for any problems after assembly or during assembly, for example, if the protection board is disconnected incorrectly, the battery will be damaged, the charger failure will cause battery problems, and the assembly error will cause battery problems. We cannot provide return or exchange, for the battery damage caused, if drum bag has been welded, we will not provide return or exchange. If cell of the battery is assembled, no protection board will be added, and drum bag of the battery will not be returned or exchanged. You cannot directly give negative comments if you do not provide a refund for these reasons. We should not give negative comments because of the express company. If you do not accept it, please do not buy any products of our company. The battery unit can only be returned or exchanged without use (the electrode is intact, there is no welding, no wear, and the appearance is intact). The test time is 2-3 days after arrival. If the time exceeds, the battery is no problem.

For return and exchange!
