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

Easy 2-minute swap-in for the existing battery in our home alarm system. This battery is the same brand and spec as the one I had, so I just reconnected the wires, and it resolved the beeping from our panel telling us our battery was low. The previous battery lasted about 4-5 years, so I'm expecting the same from this one.

Bought for a spare for when things go poop.

Perfect replacement for our security system back-up battery.

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.

I rarely leave feedback but felt I needed to after the assistance I got from this seller. The item I bought (backup battery for alarm system) had many reviews of old, faulty batteries or items that did not match the description. While it has only been a week, the battery I received had a manufacture date of this year and matched the product description. I replaced my old battery hoping to be done with the beeping errors, but unfortunately after a few hours, the alarm system chirped again with the low battery error. I then read online that it can take up to 48 hours to charge the new battery. After 3 days I was still getting the low battery error. Time to call Amazon and complain. Amazon tells me because the item was shipped directly, they could not refund or replace the item, but then connected me with AAA Security Depot. That customer service rep told me they would replace the item it needed, but first wanted me to try resetting the alarm system by unplugging it for an hour putting it into test mode. I thought they were trying to string me along, but low and behold after doing as I was told, the error went away and the battery seems to be working fine. While the longevity of the battery is yet to be seen, I want to appreciate the seller for their friendly and helpful customer service, and hopefully I can update this review in a year or so with a positive battery status. ***** Update ***** One thing they didn't tell me was that often the transformer will go bad alongside the battery. The battery only lasted a few months before I got low battery updates again. When I contacted AAA about the issue, only then did they tell me about the transformer. Long story short, I ended up purchasing a transformer and soon after another battery and all is well know, but I wish I had known earlier.

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.
