BX1500G Behavior erratic

Purchased 20 Feb 2011: Original Batteries.

Before I purchase batteries I want to see if I should. There are some odd symptoms:

• When the power is turned on, the UPS LED shows a power input of 262, 40, 50, ... before settling to about 120V. No load applied.
• When no load is applied, the UPS operates normally.
• When a 115W load is applied and the UPS has input power, the UPS intermittently
  • Shows input voltage cycling (see above)
  • Alternatively shuts down and restarts.
  • There is a ;clicking' noise (no beeping).
  • The battery LED  shows full.

It is (quite) possible that a new battery is needed, but the voltage cycling on/off state cycling and being unable to carry a load is baffling. The bottom line, do I need a new battery?

Hi Arthur,

With the symptoms you are describing, it sounds like there is an internal issue with the unit itself, not the battery. A bad battery would not affect the AC voltage readings or frequent clicking like that. With the unit being at least 6 years old, it is near end of life anyway (expected life is 7-10 years), I would recommend unit replacement.
