What is the proper method of charging the batteries in a vehicle with dual batteries? Specifically my 2015 Ford SuperDuty Diesel.

The second cable connected(the negative) should be connected to a bolt on the engine away from the battery(ies) that might be gassing, and cause a battery explosion. Also that is the first cable you disconnect. Chris

If you wish to be totally picky, connect the positive clamp on one battery and the negative clamp on the other battery.

Hooking up one will take care of both. If you truly want to charge each separately you'd have to disconnect the correct wire. Of course, I'm assuming that.
