Error code L.02 and B.02 SMC1500-2UC

I received  L.02 and B.02 error codes on my 4 year old SMC1500-2UC. After a hard reboot that entails disconnecting the battery leads the unit restarted and now shows code L.02. Gong into the menu I also found rb.0 with a battery icon with x in the middle.  Reply for photo link if needed

The battery is end of life - replaced it with a APCRBC132 cartridge. Once the new battery has been installed update the battery installation date.

Doing so will reset the internal counters and adjust the charging lookup tables. Let the new cartridge recharge for at least 24 hours or when the system indicates the battery cartridge is at 100% SOC.

Manually initiate a Self Test and let the system return to 100% SOC. Finally, initiate a battery calibration via the LCD Menu / APC Power Chute software.

Insure there is at least 30% attached load connected to the system. Once complete the operational runtime displayed on the LCD will be more accurate. 👍
