Tommygunn Posted December 25, 2017 Share Posted December 25, 2017 It looks like I´ve got an alarm panel battery problem because there have been a couple of power outages in the past few days resulting in alarm activation. Therefore, I was thinking, can I simply wire up a car battery instead of the low capacity battery that´s installed in the panel? Will there be any problems with the panel charging circuitry or is it essentially a straight swap, so to speak. I have a Honeywell Accenta Mini G4 panel. Cheers, Tom.

PeterJames Posted December 25, 2017 Share Posted December 25, 2017 It wont fit, and the panel isnt capable of charging it, other than that it will work. But you are better off replacing it with a battery designed to fit and work with your system. It will hold your panel up for at least 12 hrs and will fully recharge after 24 hrs Link to comment https://www.thesecurityinstaller.co.uk/community/topic/41822-can-i-replace-my-alarm-panel-battery-with-a-car-battery/#findComment-472505 Share on other sites More sharing options...
sixwheeledbeast Posted December 25, 2017 Share Posted December 25, 2017 You need a replacement battery not a bigger one. They need replacing over time like all rechargeables.

Tommygunn Posted December 26, 2017 Author Share Posted December 26, 2017 PeterJames, Quote It wont fit... I presume you were joking? I will be replacing it but I just wanted something as a stand-in for the time being on the end of some bodged in fly leads. It won't charge, ok, I'll leave it in that case. Anyway, I've just got back and pulled out the battery and it is reading less than 5V, so it be dead. I've also disconnected the piezo on the bell box just in case there are some more power outages, silent alarm for the time being. Cheers, Tom.

I wasnt, you would be surprised at the daft questions we get asked here, so I never assume anything. I just tell it as it is. 1 Link to comment https://www.thesecurityinstaller.co.uk/community/topic/41822-can-i-replace-my-alarm-panel-battery-with-a-car-battery/#findComment-472514 Share on other sites More sharing options...
