* 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.
The guaranteed value over an operating temperature range from -20 to +60°C is 3.4V ± 0.15V. (Actual value:
3.4V ± 0.20V)
* 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.

Under no circumstances should trickle charging, which is used for nickel-cadmium batteries, be used. Ignoring
this precaution will cause the battery voltage to rise to about 5V, resulting in a deterioration of performance.
