I've never had an uninterruptible power supply and think of buying one. What not-so-obvious things should I not do to the UPS so that it lives longer?
I don't mean some obvious abuse like dropping/exposing to direct heat/exposing to wrong voltage. I mean less obvious things like its not acceptable to leave an acid battery UPS unplugged for long time after it has been used because some chemical processes start in half-discharged batteries and render the batteries unusable. What other misuses should I know about?
