Silly question I'm sure; could a plain 12v battery charger be used as a power retaining system?

No, it will try to pass too much current (amperage) for the system to deal with. You need something like a Ctek 7200 battery maintainer, which has a specific "supply mode" setting specifically for this purpose; while plugged into the lighter socket, it supplies the correct voltage at low current and without the voltage "ripple" normal battery charger's put out.
Just remember: When connected to the Ctek in the supply mode, your battery positive cables remain "hot" even when disconnected, so they should be wrapped in a non conductive material, like a plastic or rubber bag, to prevent it from shorting while you pull out the battery.
