UPS uninterruptible power supply battery assembly

What is an uninterruptible power supply (UPS)?

An uninterruptible power supply (UPS) is just such an alternative source. A Uninterruptible Power Supply (UPS) generally consists of a rectifier, battery charger, a battery bank and inverter circuit which converts the commercial ac input into dc suitable for input to the battery bank and the inverter.

When should you replace your UPS battery?

If your uninterruptible power supply (UPS) is the lifeline of your equipment during an outage, then the battery is its beating heart. Whether you're using a UPS at home, in a small office, or for critical infrastructure, knowing when and how to replace the battery can prevent costly disruptions and extend the life of your system.

How does a ups charge a battery?

At the heart of the UPS is the rectifier, which converts AC power from the main power supply into DC power to charge the battery. The battery serves as a backup power source and is typically rechargeable. During normal operation, the rectifier charges the battery while providing power to connected devices.

How does an UPS battery work?

When the main power source is present, the UPS continually charges the battery through the rectifier while simultaneously supplying power to the system through the inverter. This ensures that the battery is always ready for use in the event of a power outage.
