Re: Two backup batteries in my system?

Battery going to big (main) circuit board is the security panel
battery.  Other battery (Altronix) is for secondary power, probably
used to power motion detectors or such.  Take info to batteries plus
or Google/order online.  Disconnect leads.  Reconnect.  Voila!
