First things first. You need to take the battery out, recharge it fully and have it load tested. I suspect your current battery is toast due to ? Second you should never connect batteries of differeng ages together. The weak battery will discharge the good one. So be prepared to buy two batteries. NOT those over priced die hard dual function things either. Do some research for true deep cycle batteries. They may cost a bit more but with peoper care will last much longer. As for connecting? + to+ and - to - for the two 12 volt batteries. Connect the + from the trailer to + on one battery ans - from trailer to - of the other battery. You then have one giant 12 volt battery.
What he said!
if you have room, I would go,with two 6V golf cart batteries in series.
