UPSs generally contain lead/acid batteries. The worn-out battery should not be disposed of in a landfill or incinerated because lead is harmful to many organisms. Lead batteries recycle well and you can sometimes get money back for them.

It is strictly not recommended to create a self-build uninterruptible power supply since they can be hazardous if not built correctly. It is best to buy them in specific electronic shops, or even online from shops like Amazon.
Disadvantage: Capital cost, efficiency losses, added maintenance and service costs.

If there is no power, the computer simply cannot function. There are devices called Uninterruptible Power Supplies (UPSs) that can provide power for a short time after a power outage, by using a large battery.

Practically every uninterruptible power supply (UPS) uses batteries, but the UPSs that use them primarily are those for low power devices, like computers. Obviously, you wouldn't want a UPS for an entire city to be run on batteries, so that's where other options, like diesel generators, come in handy.
