When did you last check the batteries in your UPS?

If you've ever suffered a serious power failure and your server crashed as a result then chances are you'll probably check your installation more regularly. If you haven't checked them in the last year then do it now - don't wait for them to fail and find out the hard way.

A typical UPS battery installation for a small server will have a typical design life of 3-5 years while large installations may have batteries with life spans up to 10 years.
