·         Q. What's lifetime of a UPS ?

Most plug-in UPS are workable for at least five years. We'd advise you to change the batteries every three to four years. For larger equipment, we maintain equipment for twenty years old and still going strong.

·         Q. How to maintain a UPS ?

There are three simple methods:  Never overload your UPS, never connect any home electronic devices such as cooling fan to your UPS. This may cause malfunction of your UPS. Discharge the battery in a consistent interval, once a month or once two months.  You can do this by turning on the UPS without connecting the mains.
