Utterly Astonishing Uninterruptible Power Supply Battery Lifetime!

Popping the cover on the NCR UPS's battery box lead to quite a surprise. What's your record for UPS battery lifetime?

I also popped the cover on the UPS "power unit" and it's a good thing I did. The main circuit board had gotten loose. A little diddling around got it right back into place and everything is fine.

I may have quite seriously sold this thing short in terms of its extended runtime capability. There are 96 amp-hours worth of batteries in that box!
