When we originally had the box installed, we had a home phone line, but a few years later we changed over to Vonage, and when we did, we had an issue with the box, and had to have a technician come out and make a few changes and charge us a hefty ~125 bucks. I have a alarm system with a DSC Power 632 PC1555MX box. In summary it is all a matter of your preference. If you don’t mind paying a little more for the 5Ah version you will receive a higher capacity battery, which can offer you a longer runtime.This is my first post, and I am hopeful someone can help me out. Keep in mind that in most cases as the Ah rating goes up so does the size of the battery!

As long as the battery you want to replace has the same voltage and dimensions it is okay to substitute it with a different Ah replacement. Amp-Hours basically show how much energy a battery holds.

As the dimensions of the 12 Volt 4Ah battery and the 12 Volt 5Ah battery are exactly the same, they are interchangeable. Simply put both versions will fit in your application and will work fine. What is the difference between the 4Ah battery and the 5Ah battery?
