Battery Terminal Nut Torque?
What is the spec for torque on battery terminal nuts? I've seen 71 in. lb. and 89 in. lb. and don't know what is correct. It is probably trivial, but I got a new in. lb. torque wrench and am looking for opportunities to play with it.

This is the first time I have ever heard anyone ask about a battery terminal torque...
Honestly Im curious to hear what it is myself... Its going to be super low... perhaps 25-30 inch lbs? It cant be much.
BUT, I have always used a 1/4" socket set and literally just apply wrist tight... or just past snug... Just enough to remove any side to side movement... Of course thats not a calibrated torque... but I dont think you can go wrong as long as you dont go over board... Just enough to stop it from moving then add a slight snug to that. You may want to use a socket DRIVER... this way you cant really over torque it...
Keep us posted.

I hope that it specified INCH or FOOT lbs... there is a HUGE difference... We have had customers in the past who have used ft/lb torque wrenches on in/lbs applications. Good for me because I get to sell them new bolts but bad for them because its a headache to deal with after its done.
The difference is worth mentioning.

Hand/wrist tight is fine. Use a small ratchet.

So 71 inch lbs would be about 5.9 ft. pounds. Correct?

Feel free to laugh. I should have spelled it out instead of abbreviated as it was in the manual. It says it as follows "71 lbs in" i.e. lbs (pounds) in (inch) as I stated previously. I know the difference and I am not stupid.
So 71 inch lbs would be about 5.9 ft. pounds. Correct?

72in = 6 foot, so 71 is pretty close.

I know it sounds funny to those of us who know... But I have delt with people who had no idea... I had a guy break 10 of his ARP studs before he called me complaining that they sucked... After a while of speaking with him I just started to put it together... He torqued these studs to 85-90ftlbs when it should have been 85-90inlbs... thats a HUGE difference... and it cost him just over $100.00 to learn the difference.
Also... I did not catch the (in lb) in the first post... but either way, it is still worth mentioning and I was not in anyway suggesting you did not know what you where talking about... I just wanted to point out the obvious so people who are new to "TOOLS" dont learn the hard way.
