You do not need two sets of terminals.
Banner uni bulls were manufactured with 2 sets of terminals purely to enable a universal fit, depending on exactly where your positive and negative leads were situated. So as long as your replacement battery is the correct physical and electrical size, you only need to make sure that it has positive and negative terminals in the correct position for your vehicle and that the terminals are the right shape for your connections.
That is what I thought. Thanks very much for the confirmation.
