    XY problem. Better to state what you are trying to actually do. Commented Oct 18, 2022 at 0:35
  • Please explain your goals. As the top answer indicates, you can get a 12v battery charger at many places. Does that actually accomplish your goal? Probably not unless the goal is to have marine batteries sitting around fully charged doing nothing.

12 volt battery charger, sold in any place that sells batteries.


A multi circuit battery tender would do the job. But again, what are you trying to accomplish? to moderators: I wanted to post this as a comment, but can't bc you can't post pics in a comment. sorry.
