How do you test UPS batteries?

Most uninterruptible power supplies include automatic battery testing which typically takes place every 24hours and is a very short-term test of the entire battery set connected. Whilst this gives a good indication as to the state of the batteries we also recommend individual battery block testing during a preventative maintenance visit using a conductance measuring handheld battery tester. Results can be recorded over each visit and compared to identify weak battery blocks. Over several visits handheld UPS battery testing provides a very accurate picture as to the state of the batteries and their health.
