e) Keep to the charging time!
The best protection against battery overheating is
not to
exceed the proper charging time.
If you wish to calcula-
te the time exactly, please refer to the technical data for
information about the charging current required.
You can take the values in the following table as a rough
guide:
1.2V NiCd battery 300 mAh
500 mAh
1200 mAh
Charging time:
1.5-2 hrs.
3 hrs.
9 hrs.
1.2V NiMH battery 650 mAh
1700 mAh
3000 mAh
Charging time:
3 hrs.
9 hrs.
15 hrs.
9V NiCd battery
100 mAh
Charging time:
5-11 hrs.
9V NiMH battery
150 mAh
Charging time:
8-15 hrs.
Warning:
Batteries with a capacity of not more than 300
mAh should not be charged for more than 2 hours, as
they would become overcharged and overheat.
All charging slots and 9 V connections have separate char-
ging current controls. You can therefore charge completely
different batteries at the same time – provided you observe
the
different charging times
, required for batteries with
different capacities.
f) Charging time: Automatic cut-out
If you have loaded four batteries of the same type in the
1.2V charging slots, you can use the automatic cut-out
feature. With this feature, the appliance switches the 1.2V
charging slots over to trickle charge after the pre-selected
maximum charging time.
This function is available for the 9V connections only.
Turn the
knob
to about the time required (you can
determine this time by referring to the table opposite).
At the end of the charging time, the appliance switches
over to trickle charge, and the
green LED
indicator at
the "Battery" symbol is fully lit.
If you
do not want to use
this function, set the knob to
the maximum charging time of "15 h".
