Battery is a perfect replacement — fit, connectors, size. Glad to find this. Hope it lasts even close to its predecessor, which was close to 20 years!

Easy to install while just removing the wires from the old one and transferring them to this one. Exact dimensions of the prior one and time will tell on how well it performs.

My home security system uses this type of battery and I was easily able to replace the one which I had in place. These batteries tend to last a good 5 years or so in the current usage.

Vought thia for my home alarm system main controller box that had a weak battery and was giving an trouble code. After a litter research I determined that the error was due to a bad battery pack. I replaces the battery and it was good to go. The price on was about half when the local battery store wanted. has some of the best prices around and I wouldn’t shop anywhere else.Definitely recommend this product to anyone looking for a battery replacement.

Country_hick –
This was used to replace a 100% dead 8 year old battery. It works as well as expected. It provided the power needed for a respectable amount of time. I have no complaints. I expect this battery will continue to be dependable as it is still holding up well almost a year after it was purchased. For the price I would buy this battery again. These batteries are supposed to have a life expectancy of 3-5 years which I hope to surpass. When this battery has to be replaced it will have been replaced at a very reasonable yearly expense.The only issue to be aware of is look at your leads. Are the positive and negative on the correct sides of the battery? Are the terminals the small or large ones that you need? Although a smaller battery slip on connector will work to provide electricity while using a larger connector cable the larger connector cost the same money so buy the correct battery.
Robert H Bertelson –
Seems to hold a charge very well.
BILL CONNOT –
It is hard to give this a rating yet. The one that came with the fencer lasted over four years, not this brand. I have only had it in use for 1 month, and seems to be working great so far. I will let you know more in three years and 11 months. But I don’t think you can go wrong for the price and free shipping!

I had a low battery alert on my home alarm touch pad last month. I purchased and replaced my old back-up alarm battery with the Mighty Max. The low battery alert disappeared. Time will tell if this battery deserves the 5 star rating I gave it. I hope so since it was a reasonably priced 12V-5AH battery.

I bought this to replace a dead battery in my Job Rocker Max speaker and it worked perfectly! The manufacturer battery had stopped holding a charge. I saw posts of people replacing the old battery with this Since the manufactur’s batteries typically die after one year. The switch out is very easy and only takes a few minutes, and now my Job Rocker Max is working like new again. Thanks Mighty Max!!!

this is a backup battery, only needed when I have a power loss. It is guaranteed for five years and the last one worked for close to eight years. What can I say? I only bought the battery a month ago. I am assuming this one will work for at least seven or eight years. Check back with me in five years and I will know more.

Seemed to be fully charged because my alarm pad showed a full charge. Don’t know how long it will last, but the price was right and fit in my alarm case with no problems

The delivery time on this battery was terrific. The cost is very reasonable considering other suppliers, local and online. I installed immediately and working great. The important question is how long will it last. My last one purchased at a battery store lasted only two years and was over 2x more expensive.
