NOVA AND NOVA PRO
Safety and operational considerations
8
❑
If even one deteriorated battery cell (or just one of a different type e.g. capacity,
chemical design) can cause disrupted charging of the entire battery pack which could
lead to overheating of the battery pack and a significant decrease in the operating
time.
❑
If no improvement is achieved after performing several charging/discharging cycles,
the state of each individual battery cells should be determined (by comparing battery
voltages, checking them in a cell charger, etc). It is very likely that one or more of the
battery cells could have deteriorated.
❑
The effects described above should not be mixed with the normal battery capacity
decrease over time. All charging batteries lose some of their capacity when
repeatedly charged/discharged. The actual decrease in capacity compared to the
number of charging cycles depends on the battery type. This information is normally
provided in the technical specification from battery manufacturer.
