But the load is used for emergency lighting, which is more important than battery life. JavaScript is disabled.

Low output voltage reading on a UPS that uses a step approximated sine wave

Self Biased vs. This voltage is the fully charged voltage of a standard SLA battery. On a typical alarm system, with say 1 - 2 short power failures per month, the battery will last much longer. Most inverters output a square wave, and most multimeters are not true RMS, so if you measure a square wave AC voltage on a meter calibrated only for sine waves, you will get an inaccurate measurement.
