Low battery warning on a UPS means what?

A low battery warning on a UPS generally means that the batteries need changing. If a power cut has occurred, the batteries maybe discharged. This is to maintain the load.

As a result, the batteries should recharge when the mains power is restored.

The low battery warning indicates that the battery voltage has reached a preset low level (Low battery warning on a UPS). Modern UPS carry out regular battery tests, so it’s possible to find out that the batteries need changing before it’s too late (i.e. during a power cut).
