Is there a suggested torque poundage for battery terminals?
After reading the problem with the beach cart below- I just do not remember ever reading about this before
thanks I used to worry about tightening too tight and snapping things- Now I am old and I wonder if I am getting them tight enough |

Last I saw from the gurus is like 110 inch/pounds.. So like 9 ft/pounds. Snug it and stop..

Re: Is there a suggested torque poundage for battery terminals?
Attached are the specs for Trojan Battery, but all would be about the same.
The most common type terminals used in golf carts are the Embedded Low Profile Terminal and Embedded High Profile Terminal (ELPT & EHPT), which is 95-105 lb/in, which translates to 7.9 - 8.8 ft/lb, so 9 ft/lb is about right. When I had stud type battery terminals, I used a socket with a screwdriver handle drive or a short handled 1/4" drive ratchet so I didn't accidentally over-torque the nuts. |

edit to add I just checked mine with a 1/4 beam bar torque wrench, and they were between 60 and 65 inch lbs, have had no problems at torque |

Re: Is there a suggested torque poundage for battery terminals?
Trojan Website says the following.
Proper Torque Values for Connection Hardware Flooded Automotive 50 – 70 in-lbs Side 70 – 90 in-lbs Wingnut 95 – 105 in-lbs LPT 95 – 105 in-lbs Stud 120 – 180 in-lbs LT 100 – 120 in-lbs VRLA Button 90 – 100 in-lbs LT 100 – 120 in-lbs My T-875s are LPT type lugs. I purchased a 1/4" drive Torque Wrench and set at 100 in-ibs. I must say that it was a little scary how tight that is. Hope this helps. M |

The studs on Trojan GC battery are 5/16" diameter and if you use a wrench that is 6" long, 19.2 ft/lb of torque will be applied to the threads for each pound of force applied at the far end of the wrench. Technically, you'd have to subtract something like half the width of the nut from the length of the lever arm, but the point is that applied torque adds up fast when you use long wrenches. |
