2.8.4. Battery function check
Battery capacity is the amount of electricity given by a fully charged battery
until it is discharged to reach the final voltage. Battery capacity changes
throughout the service life. During operation, the capacity remains stable
for a while, and then begins to gradually decrease (residual capacity).
Residual capacity can be estimated by special devices (battery capacity
testers). It is recommended to estimate the battery condition once a year.
Using a battery with a small residual capacity reduces the uninterrupted
operation time of the switch. Switch batteries operate in the floating mode.
The service life of the batteries supplied in this kit (if included) is 5 years
under normal conditions. When the switch operates with frequent power
outages or in hot climates, the battery wears more rapidly. If it is not
possible to test the battery as described above, we recommend replacing
the battery every 2 years.
