In parallel 2x2. I assume it now has 6 volt batteries in series, or 2 12 volt batteries in parallel.
If the + are all wired together, and the - wired together, they are in parallel. If they are + to -, then 2 6 volt batteries are wired to make a 12 volt battery in 2 boxes, and that would be in series. Each cell is @2.1 volts. So a 6 cell battery is 12.6 volts fully charged, at rest (when new) Assuming we are talking about a typical lead-acid battery, like a SLA battery used in a UPS.
In our old military surplus Sea Scout boat, it had a 24V electrical system, and we had 4 6V batteries wired end to end to make a 24V "battery bank" Way easier to move a medium sized 6 volt battery than a massive 12 volt 8D monster.
All your batteries should be the same make/model and age, or darn close in age. Otherwise the new ones will drain into the older weaker ones to try and equalize the whole system.
