Therefore, it is recommended:
To completely charge the batteries
To completely discharge the batteries (can be performed with normal working with the
instrument).
Repeating 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 performed
automatically.
After performing this procedure, a normal battery capacity is restored. The operation time of the
instrument now meets the data in the technical specifications.
Notes:
The charger in the instrument is a pack cell charger. This means that the batteries are connected in
series during the charging so all batteries have to be in similar state (similarly charged, same type and
age).
Even one deteriorated battery (or just of another type) can cause an improper charging of the entire
battery pack (heating of the battery pack, significantly decreased operation time).
If no improvement is achieved after performing several charging/discharging cycles the state of
individual batteries should be determined (by comparing battery voltages, checking them in a cell
charger etc). It is very likely that only some of the batteries 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 battery type and is provided in the technical
specification of batteries provided by battery manufacturer.
