Monitoring the battery
voltage
SIMA² monitors the battery voltage at cyclic intervals, thus detecting any potentially
weak buffer capacity at an early stage.
Interval of replacement
SIMA² batteries must be replaced at the earliest once every four years. This time
interval depends on the frequency of use. When used more often, the lifetime might
be significantly higher.
