Seeking help Buying new batteries

Hello all. Thank you to everyone who helped me diagnose the problem with my golf cart. I am in need of six new batteries. The current ones are 6 volt. I have 6 of them and they look like normal batteries. The new batteries I am finding have terminals that look like raised angled squares with a hole in the middle. Here is a silly question. Do these require special connections and/ or are these the proper batteries? My current have the cables screwed down. Do i just screw on the cables to these terminals and if so do I need special screws washers and locknuts? I am having trouble finding batteries in 6 volt under $100.00 each and these are more reasonable in price. Thank you!
