UPS Parts: 1. Rectifier Charger
- converts AC to regulated DC
- charges the battery
- input power to the inverter
2. Storage Battery
- DC input to the inverter during voltage drops or upon failure of the normal AC line
3. Types of Battery * Lead Acid Battery
* Antimony (car battery) - Life is 3 years
* Calcium - Life is 20 years, Cost is 2 to 3 times the antimony
* Nickel Cadmium - 500W or Low, memory problem 4. Static Inverter
- converts DC to AC
- without moving parts
5. Static Switch
- Normally use to automatically transfer load from the preferred sources to the alternate source when the preferred source is lost

Thanks for sharing. I have UPS back home which comes in different sizes. It's right that we have at least UPS back home so that our equipment or PCs are protected from sudden power shut down.
