What to do if Liebert Nfinity says 'Battery Test Weak Battery'?
If your Liebert UPS reports 'Battery Test Weak Battery', depending on the age of the batteries, it may be appropriate to replace all batteries in the system. Schedule a battery test so that the system operation is double-checked once the batteries become fully charged.
What to do if Liebert UPS show 'External Battery Module Warning'?
If your Liebert UPS displays an 'External Battery Module Warning', verify proper connections between the UPS and the Non-Modular Battery Cabinet. Reenter the amp-hour rating for the external battery (set the amp-hour entry to zero and press the return key, then reset it to the appropriate value for the external battery). If the problem persists, the external battery should be replaced.
What to do for Liebert UPS 'Load Exceeds Battery Module Capacity'?
If your Liebert UPS indicates that the 'Load Exceeds Battery Module Capacity', it means the measured load on the output will cause the battery modules to exceed their limits if the UPS transfers to battery mode.
