14 reviews for 6V 1.3Ah Replacement for WKA6-1.3F Battery

  1. Customer

    Battery works great and was as expected

  2. JayP

    This worked in a GE Simon XT alarm but required a little modification. It was slightly too tall to snap in so I had to file down the two corners so it would fit. It only took a few minutes to modify. It looks like when the manufacturer assembles the battery that it doesn’t seat completely flush which makes it a little too large.YouTube has an excellent video on how to do the battery replacement. Just search on Installation in GE Simon XT alarm system

  3. Pretty fly (for a white guy)

    I purchased one a little over a year ago and was perfect. This new one was 1/8 inch taller and my system required it to be exact. I had to trip device plastic for it to fit. If you have exact fit needs it may not work.

  4. Mary Vaglica
