You leave a quality maintainer with a power retention capability plugged into the lighter socket while changing the battery. We do it just about everyday to maintain radio station settings, seat memories, etc.

Hi
Do you mean something like this CTEK XS3.8 12v 7 Step Battery Charger.
Also could you connect the terminals to another battery while you disconnect the old battery

No, you are asking for problems if you do that. The Ctek should have a setting called "supply" and it should be connected via your cig lighter socket.
