The beeping was annoying me and driving my dogs crazy.
-
Now, I cannot give the rave reviews and recommendations for APC.Just over an hour when the beeping increased to a scream and then died
-
Something went wrong in the factory bacause my batteries and new set started beeping and failed within an hour of a power failure.
-
Bought one in 8/2017, stopped working with annoying beeps and had to buy another in 6/2018
-
First battery lasted 8 years the started failing the test and beeping weekly.

Stopped the annoying beeping on my UPS, doing its job nicely :-)
