For years I’ve protected my office server from the harsh indignities of sudden power failures by shielding it behind a traditional UPS battery backup. For more than a decade, this arrangement has kept my pixels glowing through half a dozen actual power outages, and any number of brown-outs and glitches. Over that same period, the internal battery has eventually died and been replaced twice. I don’t begrudge the battery for failing - it’s an ancient battery tech that has more in common with the battery in your car than the one in your cell phone - but the replacements are expensive.
So when the battery failed again this week, I decided it was time to re-evaluate.
