Periodic double beeps several minutes apart

[Anonymous user]

I have a APC 1500 that has worked fine for several years.  Today it started a double beep several minutes apart.   The capacity display shows 0, all other indicators are normal.  

Any guessing on the problem?

Hi Jon,

Can you please let me know which specific model 1500VA APC UPS you are using? APC has several different models with this power rating, and audible alerts may differ slightly depending on model. By capacity display, are you referring to the battery charge icon on the UPS LCD display, or to the Battery Bar Graph (right side LED strip on the front panel of certain models), or to another indicator? Thank you.

Another indicator - it was the angled graph right above the battery charge.

I bought another unit since I didn't hear from anyone.  Thanks for replying
