But comparing true deep cycle 6 volt batteries verses true. A 1967 to 1974 beetle 42 series battery will be a suitable replacement for the original 6 volt battery. Batteries wired in parallel will equalize the charge with higher charges flowing to lesser charges until equalized.

They are also smaller in length and width and more likely to fit in the designated storage area of your rv. You use this wire to connect between the 12 volt battery and the 6 volt light bulb to switch the power to 6 volts.
