Safety and operational considerations
9
❑
If the instrument is not to be used for a long period of time, remove all batteries
from the battery compartment.
❑
Alkaline or rechargeable Ni-MH batteries (size AA) can be used. Metrel
recommends only using rechargeable batteries with a capacity of 2100mAh or
above.
❑
Unpredictable chemical processes can occur during the charging of battery cells
that have been left unused for a longer period (more than 6 months). In this case
Metrel recommends repeating the charge / discharge cycle at least 2-4 times.
❑
If no improvement is achieved after several charge / discharge cycles, then each
battery cell should be checked (by comparing battery voltages, testing them in a
cell charger, etc). It is very likely that only some of the battery cells are
deteriorated. One different battery cell can cause an improper behavior of the
entire battery pack!
❑
The effects described above should not be confused with the normal decrease of
battery capacity over time. Battery also loses some capacity when it is repeatedly
charged / discharged. This information is provided in the technical specification
from battery manufacturer.
