UPS fails to read battery percentage

[Richard71]

Apc power supply unit fails to monitor the battery percentage as reading 0% this is still after a complete new battery purchased, but still the same condition

The proper steps when replacing the RBC are outlined below if applicable. Keep in mind the RBC must be allowed to fully charge for a minimum of 24-72 hours depending upon the capacity:

Date: Update the battery installation date via APC Power Chute Software. Doing so resets internal counters and adjusts charging tables if applicable.

Self Test: Manually initiate a self test via LCD, Power button, Power Chute and let pass and recover to 100% SOC (State of Charge).

Battery Calibration: Manually initiate a battery calibration via LCD, Power Chute with a minimum of 30% attached load. Once complete allow the system to recover and recharge the RBC to 100% SOC.

The LCD will now reflect the operational runtime more accurately when the system engages battery only mode.
