Electrical Question (Paging Jim Day)

[Smthtnnr]

I got tired of my 10ah fish finder battery dying on the water, so I bought a new 18ah 12v battery, that I found a good deal on. However, I didn't notice until I got it that it has entirely different terminals that the quick connect and disconnect terminals I'm used to. Here are a couple pictures of the terminals, they are pretty big maybe an inch long.







They are nuts and bolts connections, and I was wondering how I could adapt them to fit my fish finder wiring, preferably keeping the quick connect/disconnect capability. Thanks for any help!
