    Always check your UPS batteries...

    So we had been having some power problems the last couple days, due to a substation glitch. I figured I would be fine since all my stuff is on separate UPS systems.

    At 3:30am when they shut the power off for repairs, my desktop PC goes down right away, and the Smart-UPS 1250 is making some short beeps and clicking, trying to start itself back up on totally dead batteries.

    Good thing the UPS on the server rack (same model) was still going strong, and I was able to shut that down with no issues.

    On top of that, when I was trying to use my laptop to shut down my file server, the battery contacts were flaky, causing that to shut off randomly.

    Oddly enough, I had rebuilt both UPS's around the same time, but with different batteries. I think one had Universal Batteries in it, and the other had Gruber batteries. I wonder which set died early. Or perhaps it was the UPS itself?

    I'm pretty sure it's been less than 2 years since I replaced the batteries, but I guess I still should have done some periodic testing... Lesson learned

    Bad batteries are very much like bad caps.
    The gel cells bulge and stink and won't hold a charge.
    They fail anytime from two to four years.
    They have all sorts of wierd names on them yet all look alike.
    Come in a large array of sizes and ampere hr ratings and are a PIA when they fail.

      i have found out lately that universal and gps/gruber batteries are junk.
      they are shot after as few as 20 cycles in wheelchairs.
      compared to several hundred cycles with east penn/deka or mk which are made by east penn/deka.

        I ordered a set of those cheap Zeus batteries from Ebay to see how they compare.

        If those don't last more than a year, it looks like I'm stuck paying for the really expensive ones that actually last 3-5 years.

        How are Yausa or CSB as far as durability?

        The ones that died in my UPS were only cycled once or twice, if that.

        Figures that when you shell out the money for batteries, you don't need them until they're dead, but if you didn't have the UPS, the power would probably go out constantly.
