An UPS is a battery-operated system that can protect electronic equipment from power outages. The most common type of UPS is a stand-alone unit, which plugs into a wall outlet and provides backup power for designated devices.
There are also battery-powered UPSes that attach to computers and other electronic devices.
Most UPS systems have two batteries: a primary battery and a back-up battery. The primary battery is the one that provides power during an outage.
The back-up battery is a spare battery that provides power to the primary battery in case the primary battery runs out of power.
To replace the battery in an UPS, you first need to remove the cover. You can do this by removing the three screws that hold the cover in place or by prying it off. The batteries are located on the inside of the cover. Once the cover is removed, you will see the two batteries.
To replace the batteries, unscrew the battery cover and remove the batteries. Be sure to replace the batteries in the correct direction, with the positive (+) side facing out. Replace the battery cover and screw it into place.
