This can also be verified if the battery capacity bar graph does not go all the way to 100% after 3 hours. If not, it is likely that the battery charger is broken and the unit will need to be replaced (an RMA will be issued if in warranty). If the unit (non-XL) has been charging for 3 hours, the battery voltage should be around 27.6V or 55.6V depending on the Smart-UPS model. If the replace battery LED is lit, then perform the following steps: The following steps can be performed on any currently produced Smart-UPS whether it is in or out of warranty.Ĭheck the battery voltage using PowerChute plus. If the LED is dark, then it will remain dark.

That is, if the LED is lit, then it will stay lit. If the above conditions are not satisfied, a power failure is simulated, a runtime calibration is initiated, or the UPS's plug is pulled from the outlet, the replace battery LED state will not change. A self test can be initiated in any one of five ways:Īutomatic timer- every two weeks from turn on (Low battery condition refers to a state when the Smart-UPS battery has almost fully discharged). For a self test to be considered valid, it must have the following characteristics: The battery capacity must be greater than 75% or the Smart-UPS must have been charging for at least 8 hours from the last low battery condition. In order for the LED to be lit or to be cleared, it is necessary to run a valid self test. Follow this document to determine if it is a true indicator. Note: There are instances when the indicator may be false.

It is important to identify whether or not battery replacement is immediately required. In a true replace battery scenario, the indicator will light 1 to 2 months prior to complete battery degradation. If the LED is illuminated, that does not necessarily mean that the UPS is incapable of supporting the load. The replace battery indicator (Red LED) is designed as a early warning signal to the Smart-UPS user.
