Constant voltage charge (constant voltage and constant resistance charge) is recommended.
Charging current is limited, so be sure to charge via a charge-limiting resistor.
The specified charge voltage must also be observed.
* If you are considering adopting constant current and constant voltage charge mode, contact SII.
Observe the specified charging voltage range.
* Charging at a voltage higher than the upper limit may degrade the electrical characteristics or lead to leakage or bursting.
* Charging at a voltage lower than the lower limit significantly reduces discharge capacity.
