Hello all, new here.
I’m searching for advice whilst brainstorming the idea of installing an additional 12v battery in my car to supply the security systems. Some context, the car in question is infamous for being easy to pinch as it is easy to access the battery, disconnect it without setting off any of the security systems as they have no internal backup battery, nor battery disconnect feature.
In short then, essentially what I am thinking is installing a second 12v battery that will be charged along with the normal battery, but only supply the security systems. That way the additional battery will always remain charged, but should the primary battery be disconnected and the rest of the vehicle be dead, the additional battery will continue providing power to the security systems.
Hopefully I have explained it clear enough. It seems simple enough but I haven’t a clue how to connect it up or what components are required. Nor do I know what the limitations of choice are for the additional battery. Preferably it can be much smaller and more compact as it is only to run the low current draw security systems and that will allow it to be tucked away discreetly.
Any help or advice is greatly appreciated.
