Now, you may want to opt for a line interaction UPS because of its advantages, which include less wear and tear of the battery, extending its lifetime. (Other flavors are much more expensive or intended for critical systems and higher power consumption.)Ī few years ago, the price differential was high enough that you had to really balance the need for particular features against cost. It can condition power, smoothing out highs and lows, and switch over to the battery within a few milliseconds. A line interactive version feeds power through an inverter from the wall to connected devices while also charging the battery. Standby units keep their battery ready for on-demand, automatic use, but it’s otherwise on standby, as its name indicates. ![]() UPSes for consumer and small-business purposes come in standby and line interactive versions. With great power, comes great power conversion A UPS typically has a light or will use a sound to indicate a battery that needs to be replaced, and it might indicate this via software running on the computer to which it’s connected.
