Amazing what cannot be found on the internet: battery terminal specifications

Hi:

I have been up and down the internet searching for the answer to one exceedingly simple question: what hole size do I need in my battery lugs, which effectively maps on to the question "what size is the stud on a battery terminal", say the ELPT Trojan. As far as I can tell, this information does not exist in print form anywhere on the internet. I've searched on specific products, say T105s by Trojan. I have asked Mr. Google about possible industry battery terminal standards. I have asked for "battery terminal drawings" and "battery terminal specifications". No joy no matter how I think of asking the question. I am stunned that such a simple and obvious piece of information cannot be found, or easily found.

My hunch is that there is an industry standard such that all golf cart batteries from all manufacturers have the same terminal specifications, and in particular I need 5/16 inch parts, but for the life of me I cannot find proof of this.

I could always contact the particular supplier I choose, but I think this is such a glaring hole in the literature that this should be answered publicly. Anyone have the scoop?

Re: Amazing what cannot be found on the internet: battery terminal specifications

Have you used a CALIPER to determine the outer dimension of your battery's posts? Any modern body shop should have a caliper for measuring. Just make sure that you are either reading a "metric" or a "Brit/standard" dimension.

Mr. May, you are a better man than I.

In, my defense to hopefully not be deemed a complete idiot, my top two hits from the Trojan web site have data sheets that only show terminal type 5. I think it fair that if I go to the horse's mouth, and the horse's mouth doesn't have the info front and center, I should be somewhat redeemed.

I am still curious as to possible standards, that is will all golf cart batteries have 5/16-18? I see a lot of talk of 8mm and 10mm stuff in the battery skuttlebutt, not necessarily specific to GC types.

Anyhow, the matter for me personally is closed and I thank all for their suggestions.

Cheers,

Boulter
