Not allowed to use if current capacity of the charger is not big enough to maintain the specified charging voltage during float.

Regulation range of controlled voltage:
2Volt batteries:
2.40V to 2.45V

6 V batteries:
7.35V to 7.50V
(per cell 2.45V~2.5V)

12V batteries:

Initial current:
0.4C or less.
Short-time charge allowed.
Several of the same model batteries under the same storage can be charged in series.
Otherwise, they should be recharged in separate groups.

Constant Current

Charging current:
approx. 0.1C
Charging time control is recommended because an overcharge is more likely to occur.

Not applicable.

Not applicable.

Charging current:
approx. 0.1C

Combination

Tow-step charge:
Charging current:
approx. 0.4C at the first step.  0.00002C to 0.00004C at the second step.
A time control or a charging voltage detection to transfer from the first step to the second.
