BX1300LCD charge steadily dropping -- but the unit is online

[Anonymous user]

My BX1300LCD is not on battery. It's also not displaying any errors or events. Nor is it making a sound. My total load is only 43% or about 325w , with an output and input of 117v. All of these numbers are consistent with how it's been since pretty much the first moment I hooked it up.

But for the past 15 minutes, I've watched it steadily lose chage. About an hour ago it was fully charged. It's now at 63% and falling.

The unit is about three years old, so we're in the timeframe that one would think about replacing the battery. But, again, I've got no thing which suggests that there's a problem.

I've investigated the plug and it's definitely attached to the wall. The number on my Mac (running 10.4.11, if that matters) is roughly the same as what's displaying on the APU. The Mac says 63% and the LCD shows three bars.

I'm guessing it's battery, but this seems fairly inconsistent with what the manual says to expect of a "change battery" situation. Is there something else I could do to positively identify the failed battery before I shell out for a replacement?

PowerNotOn,

While the UPS is loosing its battery charge, are you hearing or seeing anything that comes from the UPS? Like 4 beeps every 30 seconds or a flashing On Battery Icon? Make sure as well that the beeper is not muted. Do you have the exact serial number of the unit, let us see if it is still covered by the warranty. Another thing that you could do is to grab a voltmeter and then measure the battery DC voltage
