We have jacks of all trades here so, I figured I'd throw this out there. I was curious about UPS systems with battery backups. Smaller ones, maybe rack mountable. I personally have never used one, but I assume that like most things with batteries, if you never allow it to discharge and charge ever so often and only have it in standby, then the batteries probably fail prematurely and when there is a power loss, the battery backup is useless. Am I right?
Do they typically have some kind of means to check battery condition without actually going through such a cycle? Either by remote monitoring or an indicator light on the device?
My client has hundreds of sites using probably the cheapest of UPS systems and on occasion, they fail without warning. We find out because the switch/router/etc connected to it shows down, but there is not way to tell if it is a site power failure without a tech being dispatched. More times than not it is a power issue rather than the device. Sometimes they find that the site had a UPS, but just couldn't power the device long enough for any graceful shutdown could be performed.
I was wondering if there are procedures, preventive maintenance for cycling UPS that do not incur an interruption of the client's services. How long would such a procedure take?
