Casil CA1240 12V 4Ah SLA/AGM Sealed Lead-Acid Maintenance-Free Alarm Battery – F1 Terminals

I got a yellow warning indicator on my alarm control panel. The code indicated the battery was bad. I had ordered this same battery 5 years ago, and it was still available for purchase, so I bought it again. After an easy installation, the battery warning indicator went out. This is a good battery at a good price.

I purchased this battery as a replacement for my home alarm system, and it works perfectly. It fits just right and provides reliable power backup. Installation was straightforward, and so far it’s holding a charge well. Great quality for the price!

OEM part for a security system for parent's place. No reported problems. Original one lasted over 10 years

This was the exact same battery needed to replace the one that lived out its life in my security system. It came fully charged and was easy to install. Great DIY value since the security company would have charged me a service call plus at least $75 for the same battery.

Bought for a spare for when things go poop.

Perfect replacement for our security system back-up battery.

Always buy the replacement batteries here on Amazon. The last a long time, perfect fit, and ships quickly.

I returned from a work trip to find that my AC was kicking on and then off a few seconds later... over and over. A little cool air was coming out of the vents... but it was constantly shutting off. I went outside to see what was going on at the unit out there and noticed that the fan was not kicking on. I was able to get it started with the help of a stick sometimes, but not anything close to normal speed. After a quick youtube search, the overwhelming diagnosis was a blown capacitor. So I turned of the breaker both inside and out... to check the capacitor configuration... and found the exact make and model on Amazon for less than $25 delivered with overnight shipping. Figured it was worth a shot. Amazon showed up the next day, and I swapped out the unit in literally 5 minutes (be sure to run a rubber handled screwdriver across the connectors in case there is any leftover charge) after noting the correct location of each wire (I took one off the old, then put it in the same spot on the new... repeat for all 4 connections(should be 3 connectors: HERM, FAN, and a dot... my dot had a second cable on it). Then I flipped the power back on... and all is well again - was so happy to see that fan humming. So maybe consider this as a first step before calling the AC guy for service... which will surely be much more time, $$$, and aggravation.

Battery working well, came in tack, no delays in shipping. will buy again in 7 years

Good product

A+++++

Product is fine, delivery was prompt the only thing was they did not send the one I actually ordered the one I received was another brand and was a 5ah. Other than that it works for what it was designed for.

Battery fits my DSC alarm panel perfectly and does the job.
