It sounds as if you have a normal side-terminal battery......what you
need is a couple of 3/8UNC bolts to screw into the sockets (just barely
tighten) to give you something to clip your charger to. As others have
stated.....note the polarity (it'll "usually" be formed right into the
plastic over top of those respective terminals...probably right on the
top cover).

By the wording of your question, I'd guess this is not something you're
familiar with so be careful or get a little help.
