UPS

We had a power failure the other day (car crashed into the pole!) and the five-year-old APC UPS on my computer only had a couple minutes of battery. The sealed lead-acid batteries aren’t really expected to last any longer than 3-5 years so that’s not unreasonable. I ordered a replacement and installed it today, seems to be working fine again. I decided to just order the “official” replacement pair of 12V batteries linked together into a 24V pair with connectors and straps to lift them out of the well in the UPS and so on for $100 instead of trying to be creative because it’s just not worth it to me. For the Linux people like me, you want to then stop the apcupsd service and run apctest as root to reset the date on the battery and run the battery calibration and the the self-test, then restart the daemon.
