* Consult with Panasonic concerning constant-current charging systems.

The charging circuit is crucial in terms of ensuring that full justice will be done to the battery characteristics.

Consider it carefully as the wrong charging circuit can cause trouble.

I Precautions regarding the charge voltage setting

I Charge voltage range

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

Guaranteed voltage is 2.8V to 3.2V 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

* It is not possible for the battery capacity to recover completely when the charging voltage is below the speci-

I Recommended charging circuits

I Mixed usage of batteries

Do not use these batteries and lithium primary batteries or other rechargeable batteries together, and do

not use new batteries and old batteries together even if they are of the same type.
