CHARGING SPECIFICATIONS
Charging Current:
Charging current should be less than the maximum charge current specified within this product specification. Charging
with higher current than recommended may cause damage to the cell's electrical, mechanical, and safety performance,
and could lead to heat generation or leakage of electrolyte.
Charging Voltage:
Charging voltage should be less than the maximum charge voltage specified within this product specification. Charging
beyond 3.7V, which is the absolute maximum voltage, is strictly prohibited. The charger shall be designed to comply with
this condition. Charging with higher voltage than maximum may cause damage to the cell's electrical, mechanical, and
safety performance, and could lead to heat generation or leakage of electrolyte.
Charging Temperature:
The cell should be charged within 32°F (0°C) to 113°F (45°C).
Reverse Charging:
Reverse charging is prohibited. The cell is required to be connected correctly. The polarity has to be confirmed prior to
wiring. If the cell is not connected properly, the cell cannot be charged. Reverse polarity charging may cause degradation
of the cell's performance, overall damage to the cell, which could lead to heat generation or leakage of electrolyte.
