2. How does a UPS battery work?

A UPS battery serves as the backbone of an Uninterruptible Power Supply system. Its primary role is to provide instantaneous power during electricity outages, ensuring there's no interruption to the connected devices.

When the main power source is functioning correctly, the UPS system charges the battery, keeping it ready to take over in case of a power cut. Once there's a disruption in the main power source, the UPS system immediately switches to its internal battery, preventing any downtime.

The power stored within the battery is in DC (Direct Current) form. However, most electronic devices require AC (Alternating Current). The UPS, thus, has an inverter that converts this stored DC power into AC power, suitable for running the connected devices. This transition happens in milliseconds, ensuring that devices like computers don't shut down suddenly, protecting data and hardware.
