The entire circuit is powered by a battery, so it stays operational even when the AC power supply fails. When the power fails, the alarm is triggered, giving you an early warning of a possible issue. By having an AC power failure alarm in place, you can protect your AC power supply from damage due to power surges or outages.

This Main Power failure alarm circuit is connected to the power grid via the transformer T1. The AC voltage is rectified by the diode D1 and is flattened by the electrolytic capacitor C1.
A short circuit occurs when a current takes an unintended path, often due to a fault in the battery protection board. If the protection circuit fails to detect the short circuit or overcurrent, it can lead to catastrophic failure. This not only damages the battery but can also harm the connected devices or even cause electrical fires.
Humidity and dust: Exposure to moisture or dust can lead to corrosion or short circuits within the battery protection board, leading to malfunction. Vibration and mechanical shock: In applications like electric vehicles or industrial equipment, batteries may experience frequent vibrations or impacts.
