    • Perfect replacement for your ADT system
Size: Standard
Review Image by Dr. Quack Quack
I purchased this Mighty Max 12V 7Ah battery as a replacement for the backup battery in my ADT home security alarm panel, and it worked perfectly. If your system is showing a low battery warning, this is a straightforward and affordable fix that most people can handle themselves. The battery itself appears well made and is a sealed SLA / AGM design, which means it’s spill-proof and designed for reliable performance. It’s rated for a high discharge rate, wide operating temperatures, and long service life, which is exactly what you want for a backup power source in a security system. Installation was surprisingly simple. I started by putting my alarm system into test mode. After opening the panel, I unplugged the tan power outlet and removed the old battery by disconnecting the negative (black) wire first, then the positive (red). I placed the new Mighty Max battery in the same spot and connected the negative first, then the positive, and finally plugged the tan power outlet back in. Once I took the system out of test mode, the panel immediately recognized the new battery and the low battery warning disappeared. The entire process only took a few minutes. Overall, this is a high-quality replacement battery that fits perfectly and restores your alarm system backup power quickly. If your security panel is showing a low battery message, this is an easy DIY fix that can save you a service call. ... show more

    • Perfect replacement battery for my home alarm system.
Size: Standard
Perfect replacement battery for my home alarm system. I had contacted my alarm company as the batteries that were available from the local battery store were outrageous in price. I must say I was skeptical at first as the cost is so reasonable but no lie here, it is perfect and I was able to hook it up in less than a minute. Do not hesitate to buy this. ... show more

    • The "Trouble 1" Killer – Perfect DSC Security Save!
Size: Standard
If you’re staring at a flashing "Trouble" light on your DSC keypad and your system is chirping at 2:00 AM, this is the fix you need. I used this Mighty Max 12V 7Ah to replace a dead backup battery in my DSC PC1555 system, and it was a total seamless swap. The Breakdown: Performance: It arrived fully charged and ready to go. The moment I swapped it in, the system recognized it, and the battery error cleared instantly. Fitment: The terminals are standard F1 size, fitting the existing leads perfectly without any crimping or modifications. Value: Why pay a security company $100+ for a service call when you can do this in 30 seconds? It’s been rock solid ever since. If you have an older ADT or DSC hardwired panel, don't overthink it—this 7Ah provides a little extra "juice" over the stock 4Ah, which is great for peace of mind during Texas storms. ... show more

Purchased two of these batteries for a Liftmaster swing gate operator. They arrived fully charged and in perfect condition. Installed them and the gate opener began working great again. We'll see how long they last.
