6v Positive ground battery charging question

When using a 6v charger, is it still positive to positive with the charger since the charger is set up for negative ground or vice versa or just disconnect the cables and charge up normal positive to positive and neg to neg?

Basically does the positve ground affect how it's charged? Thanks in advance.

 

Charge as normal - Positive to positive

 

The charger doesn't know where the pos cable is connected. All it knows is pos and neg.... Pos to pos neg to neg with or without the cables connected. You are over thinking it.

 

Thanks, yes i'm overthinking this. Don't know until you ask.
