  1. Levester Corley

    Product does not appear to be fully charged to run my security system.

  2. Flier52

    Alarm system.

  3. Josh

    battery was packed well and seems like a good value.

  4. BugChaser

    I got two to replace batteries in a UPS. The only very small issue I had was these batteries come with a protector around the positive terminal. I simply took and popped these off and they then fit perfectly. They are doing great.

  5. Bruce Carpenter

    My trickle charger never reaches fully charged status. Replacement for my fish finder… only shows 60% charge even after days on the charger. Still works okay but haven’t full discharged it yet.

  6. Web Customer

    More power and larger than my original equipment. Fit perfect in my alarm box.

  7. Lucas

    Just right as a replacement battery

    Alarm battery

  11. Byron Mitchell

    Great for hog hunting lights!

  12. John from NorCAL

    Great value would purchase again

  13. Paul

    Best price compared to ADT.com. Arrived direct from Manufacturer, in good condition. Unless mistaken, I believe this is manufactured in USA. It was fully charged. Easy to install. Low battery notice is now off. In my system these last about 4 years. It has only been a month so I can’t speak to the longevity. That’s the reason for 4 star instead of 5

  14. Gene Lawrence

    It’s a great value for the price.

  15. Dutchman

    Ease of installation Weight of battery

  16. Rose

    It works with no issues. I had someone who is familiar with installing security systems install it so he had no issue.

  17. Web Customer

    I have an Ion Explorer Extreme. Battery would show 3 bars then die. After taking apart, I had a splice on one of the battery wires. I re-spliced and put this battery in. Fit perfect and so far is working like it used too. 20 bucks is way better than buying a whole new speaker!

  18. Sand

    Easy to install. Alarm system works great now!

  19. Alfred Schreiter

    My house alarm furnished by ADT, needed this back up battery replaced. ADT offered to sell it at almost twice the cost! Received it in a timely manner, easy to install, great value.

  25. Akiravayn

    Needed a new battery for my Ion Pathfinder radio and wasn’t able to buy one on Ion’s website. This battery was the same price and it works! Highly recommend!

  46. Kelley

    It was the right size for my ADT panel box alarm. I hired someone to install it and he has no problems.

  47. Antonio J. Oliva

    The Battery Back-up System was defective from the box. The manufacturer sent me a whole new box and told me to keep the defective one. All it was a defective Battery, super easy to install and it worked immediately. It also costs about 50% of what our I.T. person wanted.

  52. Benjamin Northcutt Jr

    They don’t recharge very well. Plan on replacing every year. Very Easy to Replace in alarm panel box. $20.00 a year for battery isn’t a bad price

  53. bud

    It was shipped promptly, and was packaged safely. It came fully charged and worked fine in my alarm system. I can’t attest to its durability, yet. Ask me in a couple years.

  58. Donny Harper

    I needed to replace my four year old batteries in my gate opener control box, these were a perfect replacement at a significantly reduced cost. I’m just hoping they last close to the length the old ones did.
