Function and Working Principle
The S9129FA Battery provides backup electrical power when the primary system power supply is unavailable. During normal operation, the battery remains charged while the control system is powered.
If the main power source is interrupted, the battery automatically supplies power to essential circuits, allowing critical data such as controller memory, configuration parameters, and system clock information to be retained until normal power is restored.
Once the primary power supply returns, the battery is automatically recharged by the host system, preparing it for future backup operation.
