Attention

1. The charging current shall not exceed the maximum charging current of this specification. Charging with a current value higher than the recommended value may cause problems in charging and discharging performance, mechanical performance, safety performance, etc. of the capacitor, resulting in heating or leakage.
2. The charging voltage shall not be higher than the rated voltage of 16V specified in this specification.
The charging voltage is higher than the rated voltage value, which may cause problems in the charging and discharging performance, mechanical performance and safety performance of the capacitor, resulting in heat or leakage.
3. The product must be charged at -30~60℃.
4. If the positive and negative poles of the module are connected correctly, reverse charging is strictly prohibited.
5. The discharge current shall not exceed the maximum discharge current specified in the specification.
6. The product must be discharged at -30~60℃.
7. Product voltage is lower than 9V, please do not force discharge;Full charge before use.
