 Repeat the charge / discharge cycle
at least 2-4 times.
Four cycles are recommended in order to
restore the batteries to their normal capacity.
Notes:
 The charger in the instrument is a pack cell charger. This means that the battery
cells are connected in series during the charging. The battery cells have to be
equivalent (same charge condition, same type and age).
 One different battery cell can cause an improper charging and incorrect discharging
during normal usage of the entire battery pack (it results in heating of the battery
pack, significantly decreased operation time, reversed polarity of defective cell…).
 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.
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. Actual decreasing of capacity, versus number of charging cycles,
depends on battery type. This information is provided in the technical specification from
battery manufacturer.
