  1. M. Kauffman

    This is a plug in replacement for the battery in my UPS. Less than half of what the OEM wanted.

  2. Stephen D. Ward

    When I originally installed AT&T internet, it came with a small UPS back-up battery. This battery is exactly the one I needed to replace the original. Installs easily and works great.

  3. anthony

    It was listed as fit for a dr chipper but it was smaller than the original but even though it was smaller it works fine

  4. roy m painter

    It was what I needed and works good

  5. Fred E.

    I got this to replace the battery in my Monster Rocking Roller Speaker, it was a fight to get it back in but it does work.

  6. baker

    I was going to throw my speakers away until I saw that I could get a battery. I ordered 2 and they work better than ever expected!!

  7. Ted T

    good battery but had to wrestle with putting it in my cyberpower computer back up. Leads are backwards

  8. CaptainSportster

    Used to replace a very weak battery in my CyberPower UPS backup. Easy installation. Seems to be working fine. Cannot rate Longevity due to that fact the battery has been installed only a couple of weeks.

  9. Howgold

    The Mighty Max 12V9AH battery is the exact replacement battery for the CyberPower RB1290 battery. And it’s less expensive.

  10. Ilene, the Folks dancer.

    This battery was for the Folks dancers, music system, out in the open space for everyone to enjoy. Where there is no power system available.

  11. Jeremy Noble

    Exactly what I needed.

  12. Garth Luer

    Nothing

  13. Modoc Organ Gig

    Easy to install and was fully charged. My Cyberpower UPS worked perfectly with the replacement battery. The original battery lasted 10 years

  14. Anthony J. Fasy

    Easy to install, lasts a long time, no issues.

  15. JetFan

    Bought 2 of them and it works fine.

  16. J. Sekula

    Worked well for my Cyberpower CP1000PFCLCD. I had to bend the negative terminal a bit to match the angle, and crimp the connector a bit.

  17. Mark Simmons

    Dropped this into a CyberPower CP1000AVRLCD I bought ten years ago to handle a load fault issue, and the problem just went away entirely. Like a brand new unit. Thrilled.

    Worked perfectly for my UPS, plugged it in and it worked as it is supposed to. It’s been only two weeks, no problems so far. It is more than a year and it keeps working like a charm, perfect battery.
