I am getting a low battery notification on my keypads. I have pressed * to stop the beeping, but 
 power cycling always causes the notification to come back. Funny thing is, this battery is only 
 a few months old (replaced it this summer).
 
 I did the Elk Menu->8 (System Settings), entered my system code, and selected the battery test 
 (30 sec). When I do that, it shows 11.1 V, .220A for a few seconds, and then it goes to 13.9V, 
 .4A. I have also confirmed the voltage readings with a multimeter.
 
 11.1 V would definitely be low, but I think that is the voltage under load. Is that normal??? I 
 am not sure. I would be surprised if the battery is bad this quickly. It's an Amstron 18Ah 
 (model AP-12-180EV).
 
 Thoughts?
