2.3 Charging
The battery is charged whenever the power supply adapter is connected to the BENNING IT 110/
BENNING IT 120 B. In-built protection circuits control the charging procedure and assure maximal
batterylifetime.Powersupplysocketpolarityisshowningure2.1.

2.4 Precautions on charging of new battery cells or cells unused for a longer
period
Unpredictable chemical processes can occur during charging of new battery cells or cells that
were unused for a longer period of time (more than 3 months). Ni-MH and Ni-Cd cells are affec-
ted to a various degree (sometimes called as memory effect). As a result the operation time of the
BENNINGIT110/BENNINGIT120Bcanbesignicantlyreducedattheinitialcharging/dischar-
ging cycles.
Therefore it is recommended:
- to completely charge the battery (at least 14h with in-built charger).
- to completely discharge the battery (can be performed with normal work with the instrument).
- to repeat the charge/discharge cycle for at least two times (four cycles are recommended).
When using external intelligent battery chargers one complete discharging/charging cycle is per-
formed automatically.
After performing this procedure a normal battery capacity is restored. The operation time of the
BENNINGIT110/BENNINGIT120Bnowmeetsthedatainthetechnicalspecications.
Note:
- The charger in the BENNING IT 110/ BENNING IT 120 B is a pack cell charger. This means
that the cells are connected in series during charging so all of them must be in a similar state
(similarly charged, same type and age).
- Even one deteriorated battery cell (or just of an another type) can cause an improper charging
oftheentirebatterypack(heatingofthebatterypack,signicantlydecreasedoperationtime).
- If no improvement is achieved after performing several charging/discharging cycles, the state of
individual battery cells should be determined (by comparing battery voltages, checking them in
a cell charger, etc). It is very likely that only some of the cells are deteriorated.
- The effects described above should not be mixed with normal battery capacity decrease over
time. All charging batteries lose some of their capacity when repeatedly charged/discharged.
The actual decrease of capacity versus number of charging cycles depends on the battery type
andisprovidedinthetechnicalspecicationfromthebatterymanufacturer.
