Elk M1 Gold...
Over the past month or so, we've had the low battery warning come up a few times. After a reset, it would usually go away. But we've had a few false alarms recently, and they've usually been triggered by a motion sensor / glass break when there was obviously nothing to have triggered it.
Now, for the past two days, we've had nothing but the low battery warning - and apparently bad enough to cause the panel to shutdown.
I took some measurements:
With multimeter, battery measured about 11.05V (can't recall, I should be home sleeping right now, but am at work taking care of this)
From Keypad, Voltage displayed while on A/C = ~13.7V, ~1.36A
From Keypad, Voltage displayed while performing battery test = ~11.1V, ~.750A
With multimeter, voltage measured across battery charge points in panel = ~13.85V
I have replaced the battery with one that hasn't been used yet, and voltage measured with a multimeter was about 12.5V, while the battery test showed about 12V (though it would drop to 11.6V during the course of the test). I am still getting the low battery warning on this one. I just put this battery in about a couple hours ago, so I'm sure it's not fully charged yet.
In any case, regarding the original... Is the battery actually dead, or is the panel not able to charge it with everything it's powering (about 13 glass/motion sensors)? It has been operating fine for a long time - the low battery issue just began fairly recently.
I have read through about 20 or so other battery related posts on the forum, but haven't really come across any solid answers regarding ideal voltages and power draw limits. I've read in some posts about 11.2V, 12.5V and 12V being points at which the low battery warning is triggered. Is the 1.36A draw too much on A/C? Is the .75A draw on battery too much?
Thanks for any help and assistance! I did place a request with A-O to see if I can get the battery replaced, but last time I put in a service request to get something replaced, I never got a notice or reply.
