Handling Guidelines

1. If a fixed-charging method is applied, please adhere to the specified charging voltage.

Guaranteed voltage is 2.5V to 2.7V at the temperature of -20°C to 60°C.

If the charging voltage exceeds the specifications, the internal resistance of the battery will rise and may cause battery

deterioration.

Also with a charge voltage around 4V, corrosion of the positive(+) terminal (case) may occur causing leakage.

It is not possible for the battery to recover completely when the charging voltage is below the specification.

2.6V

2. Under no circumstances trickle charging should be used.

Ignoring this precaution will cause the battery voltage to rise to about 5V,

resulting in a deterioration of performance.
