Yes, a UPS typically includes surge protection capabilities. It guards your devices against power surges, which can occur due to lightning, utility grid fluctuations, or other electrical issues. The UPS filters and regulates the incoming power to shield your electronics from damaging voltage spikes.

The battery in a UPS has a limited lifespan, usually around 2-3 years. It is recommended to replace the battery within this timeframe to ensure optimal performance and reliability. Regular battery replacements help maintain the UPS's ability to provide backup power during outages.

UPS systems generally require minimal maintenance. It is recommended to periodically inspect the unit for any physical damage or accumulation of dust. Additionally, battery health should be monitored, and batteries may need to be replaced every few years, depending on usage and manufacturer recommendations.

The backup time of a UPS depends on the power load it is supporting and the capacity of its batteries. Generally, the higher the power load, the shorter the backup time. Most UPS systems provide backup power for a few minutes to an hour, allowing users to save their work, perform an orderly shutdown, or switch to an alternative power source.
