Notification That The Battery Needs To Be Replaced - Omron BA75T Instruction Manual

4-2-1 Notification that the battery needs to be replaced

This Battery life counter function notifies you with LED display and beep sound when the
battery needs to be replaced.
The battery life is determined by the counter function. The battery life counter operates
while commercial power is supplied after shipment. (When the ambient temperature of the
battery is higher than 25°C, the value of the counter will be incremented at a faster pace.)
The lead battery used in the unit has a limited lifespan. The life varies
depending on your storage/use environment and backup frequency.
● The nearer the end of the life is, the more rapidly deterioration proceeds.
Refer to the below-shown reference data "Battery life" for the details about the life
of the battery.
The battery deteriorates even if it is stored. The higher the temperature is, the
shorter the life becomes.
