I just changed my stock GM battery, which has only the GM side posts which you screw bolt terminals into, for an Optima battery which has both side and top posts. I'm not sure how to use the top posts, they don't seem to work the same way as the side posts since they are just a smooth metal knob without any way of accepting a bolt. Can anybody tell me how to use these top battery posts, ie how do you connect cables to them? No smart ass comments please, I just have never used anything but the GM side posts before. I basically want to do the Big Three upgrade, using the top posts since they are much easier to reach. What terminals to I need for my cables? Thanks in advance.

Most all of the manufacturers of any wiring accessories will have a top post terminal for accepting 10 to 4 gauge wires... Should be no problem for you to locate these accessories. Check Circuit City.

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Make a internet search for: car audio battery connector There is a lot of nice terminals for the top post of your battery. Check the pic.

i have an '05 gmc sierra extended cab- with a pretty large stereo. i replaced the stock battery with a yellow top optima, using the side terminals as they were (for the truck) . i bought a pair of decent tsunami gold plated top posts (similar to pics) off of e-bay for $5 a pair- helps when you are buying 4 pairs for the four optima batteries in the vehicle. i ran a 0-gauge ground from top - to the frame, and 0-gauge power from the top + back to the other batteries and amps (fused, of course). many different ways to do it, this was just the easiest and neatest for me: especially since i am always changing things. also, the pic that airwolf shows in his reply accepts the wire directly. the ones i used have two large allen bolts on top and require the use of ring terminals to attach the wires- all in what you would prefer. you don't have to spend huge money on these, but if you buy the cheapest ones you can find, you might get the cheapest thing that they could make- garbage isn't worth anything at all...

How many battery terminals like what AirWolf showed do you know can hold more than two 0 gauge wires???

i am sure they are out there(?), but i can't recall seeing any that accept more than (2)-0gauge wires. the ones i used do require ring terminals on the ends of the wire, however, with this method, you can easily put more than one wire (of any size) onto each connection- my terminals have two allen head bolts each to connect the ring terminals. if my camera was working, i would put up a pic so you can see what i mean.
