"Full" sign is shown -The battery
is fully charged
Note :
The current cannot be altered once the setting has been confirmed in the initial stage.
This can avoid the user changing the current setting accidentally while doing setting on
other rechargeable batteries. If one wants to change the applied current afterward, the
rechargeable batteries must be taken out and inserted again.
The maximum charging current of other rechargeable batteries are restricted by the
current setting of the first inserted rechargeable battery. For instance, if the first inserted
rechargeable battery is set to charge at 700 mA, then the second, third and fourth
rechargeable batteries can be only set to charging at a maximum current of 700 mA.
