Battery Backup For Laptop When Power Outage?

A UPS has three main parts :
- A rectifier to convert the AC into DC
- A battery to store energy
- A Inverter to convert the DC into AC

Fist step: You need to find out what you want to power with the UPS.
For example, you want to power a Laptop (50W) and a monitor (80W) so your UPS should be at least around 250W, that is a small UPS.

Second step: For how long you need the UPS. For example, if you want it to last 8 hours, you will need at least 250W x 8h = 2000Wh.
If the battery on the UPS is 12V, you need to attach a 2000/12 = 160Ah (two large car batteries).
Once discharged it can take days to recharge as the built in rectifier is designed for a low capacity battery.
