e) Keep to the charging time!
The best protection against battery overheating is not to exceed the proper charging time. If you wish to calculate
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 | 300 mAh |
| 800 mAh |
| 1800 mAh |

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.
Not for 9V single block batteries.
All charging slots and 9V 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) Calculation of the Charging Time
Charging Time (h) = Battery Capacity (mAh) x 1.4 Charging Current of the Device (mA)
g) Charging time: Automatic
If you have loaded four batteries of the same type in the 1.2V charging slots, you can use the automatic
charging slots over to trickle charge after the
