A few weeks ago, my Back UPS XS 800 began flashing the flashing the red "replace battery" light. I let it go for a while, because the computer on that unit hadn't been turned on in a while. So I needed to work on the computer this weekend, I turned it on, and everything works fine. Red light is still flashing, but the computer runs fine.
I left the computer on, went to run some errands, and came back to my office. The computer is off and the both the Overload and Replace Battery lights are flashing, in unison, very quickly. I figured I might as well replace the battery, so I bought a replacement, then brought everything back on line. The green light was running and everything was fine. This was Saturday.
Today, Monday, I come to my office, and the UPS is doing the dual flashing lights thing again. The computer wasn't even on at this time and there couldn't have been more than a trickle of draw coming through from my iPod.
Any idea what is going on here?
