Smart UPS C1500 error code b.02

Good Morning All,

We have an APC UPS C1500 with an alarm going off and error code b.02 displaying on the screen. We searched online to no avail. Does anyone know what this error code means?

While I can not say for sure but from what I have seen any code that starts with a B is a board level event like faulty main board, charging, charger, or the like.

Did you ever get a good answer for this error B.02 , I have the same error. It came about when I also got a L.02 code for end of life for the battery.
