  • What buyers say about Casil CA1240 Genuine 12V 4Ah SLA Alarm Battery

    I got it the day after that because the vendor shipped it the next day, despite my failure to select expedited shipping.

    It arrived on time and in good condition, despite the box being larger in oneDIMENSION than the battery, so it was able to slide back and forth in transit.

    The battery arrived exactly as it was pictured, and I used it to replace the same battery on our home alarm system, as the battery failure alert on our control panels instantly turned off after installation of the new battery.

    The battery was genuine and I was very happy with it. I had questions about a code that wouldn't leave even after I installed the new battery, but the company took time to help me with that.

    The battery came in yesterday and I was happy that the low battery warning went out.

    Common Questions


    Are they F1 or F2 terminals?


    Please let us know if there is anything else we can help you with, as these are F1 terminals.


    I would like to order the exact battery, but I don't know what will be shipped.


    I needed a replacement battery for my home alarm system because it was 5 years old.


    What is the information for charging?


    New and fully charged batteries can be purchased from me. They re- charge through the device that they operate, with electricity from your power outlet.


    Since the battery says 'Recharge after use', do I need to charge it?


    When the power goes out, the alarm system goes off until the battery is charged or the power comes back on.


    I just received my battery and it's not the same as the original brand. Has the manufacture name changed to pro power?


    No, casil is still making batteries.
