Re: Ez-go hot!
Be sure to remove any rings or watches. I had a neighbor, and there have been several posts, where rings came in contact with another post while tightening one, and got "welded" onto their fingers.
I generally use sockets on a nut-driver, but often use a wrench for the two hold down nuts. |

Re: Ez-go hot!
The studs used for battery terminals are Stainless Steel hex bolts with the hex head embedded in the lead battery post. Lead is a soft metal that is malleable, so too much torque will twist the hex head in the Lead post, permanently reshaping the Lead and loosing some of the electrical contact area between the SS and Lead, so the terminal heats up more when there is high current flow through it.
The torque specs for the embedded hex bolt type battery terminals found on most golf cart batteries in in the 95-105 Inch-Pound range (7.9-8.8 Foot-Pounds), which isn't very much and may be easy to exceed using a regular box-end or open-end wrench. When I had batteries with the embedded hex head bolt type terminals, I used a screwdriver handle 1/4 drive and socket, or a stubby 1/4 drive ratchet with a rubber coated handle, so I wasn't as likely to over tighten. |

Re: Ez-go hot!
Diddo on the rubber handle stubby ratchets (1/4 or 3/8ths) - wrist tight is accepted to be 15- 18 ft pds depending. It's real easy to over tighten ( damage) battery studs.
