Auto battery

Jan 27, 2004 35 Replies

Gang, Looking for a link which will give me specifics on the shape of the positive and negative terminals (post type) of an auto battery. I know they differ in sizes, but I'm looking for actual dimensions and tapers, etc. Haven't found anything on the 'net but I'm not that good when it comes to searching -- -- unless it's little pieces of something I dropped on the floor in the garage...... :-) Ken.



In 60 seconds of searching, I figured out that you are looking for an SAE specification. Perhaps someone here on rcm will know which one it is and how to get to it.

I have the most trouble with the little pieces on the floor.

Why? If for making connections, you can buy terminals to fit the battery posts with studs and wingnuts on them. Very common in marine installations. Most automotive stores have them. Even I, one of the world's great cheapskates, wouldn't make them. :-)

When you get a chance, there's a spring that jumped out of a switch assembly last fall. I think it landed over there somewhere 9gesturing) Rex in Fort Worth

Just a thought - have you considered taking a battery and measuring it yourself?

Just watch out for carpet burns.

Thanks - I needed that ! Ken

Thanks for the link - That'll work. Ken.

Ted, I've decided to make a positive and negative terminal to enable me to wire in extra cables for the inverter and winch lines on my truck. I HAVE been able to find terminals on ebay which will accept one 1/0, and a combination of either #4 and #8's, but I'm a cheap SOB and don't want to pay up to about $23 each for a couple of terminals. I figure with a couple of nice hunks of brass, I can make them *exactly* the way I want them. Ken.

Not necessarily, but on the newer vehicles, the factory battery clamps on the ends of the cables leave a lot to be desired, and I need to take off another cable to feed a solenoid which will feed 3 heavy cables. I'm running 1/0 winch cables to the back and to the front of my pickup, plus I need to run about a #4 to a power inverter in the cab. All these will be off a solenoid so they will be dead until I need them, but I want to keep the factory cables coming directly off the battery posts with the aux cables attached at the same location - and there ain't a lot of extra cable on the end of the factory wires so I think I can cut off the factory battery clamp and insert the end of the wire in a different terminal and clamp it down with a heavy duty setscrew. Ken.

Or for offroad (in the dirt?) work or on wood floors, use these:

They're also useful for tracking down jesus clips.

There a load rating on those things?

Yeah, generally one load per prone position.

IMO, so do the cables. :-(

Why not use crimp connectors with a ring to set on one of those marine type post to screw adapters?

If you do that, you want to squash the whole wire bundle so you should probably put a pad between the setscrew and the wire.

Ted

I've not checked into 1/0 crimp ring connectors (yet) but was thinking that the setscrew connection would be much better.

Good suggestion... Thanks Ken.
