Lack of new threads?

That group has been our customer base for 10 years, if we didn’t build “up” to and beyond their standards we wouldn’t be around and our business wouldn’t be growing.

Looks like they are using something like these as battery terminals.

They’re about $7 on Amazon.

Might be okay for a pleasure boat with an outboard motor but not the best (long term) for anything that draws significant current.

from a engineering standpoint: The flat area on the terminal end needs to have enough surface area to equal the diameter of the cable. There are differences I suppose if it is copper or aluminum cable but you get the idea here in that that flat surface also has to conduct the same amperage as the cable itself. so, I think the view here is the surface area in contact with the voltage supply and cable dia.//material … I should think the diameter of the hole is subserviant to this?

Where the fastener size becomes an issue is when it is too small to provide adequate clamping force to provide the contact area required. As my first post stated, the holes “appeared” to be very small in proportion to the lug area. Too small a bolt means that virtually all clamping force is applied to an area about the size of the nut and a portion of any washer between the nut and lug. That usually causes a coning effect which reduces clamping force even more.

Also reconsider the use of open lugs, especially in a below the deck plates installation. Closed cup style lugs (sometimes called tubular or solder type lugs) properly crimped and sealed with adhesive lined heat shrink tubing will provide excellent protection against moisture wicking and corrosion of cable strands.

Why waste time, money, and parts making inferior “temporary” cables when the same time, money, and slightly higher quality parts would complete most if not all of that job correctly the first time.

also, the thickness of the terminal end plays a part.
i guess this can get pretty complicated … again; from a engineering viewpoint!!

Trot along and have a look at the terminals on the battery.

You certainly have “The gift of gab” sir! Which can get you places I have learned far beyond what actually knowing about engineering can. Good for you, gab on :joy::+1:

I asked for the ‘standard’ you mouthy nitwit.

I was tempted not to reply but if all the battery manufacturers have chosen to make their studded terminals different for positive and negative then that’s the standard.
It is good to see that shipping has an officer that knows everything and shows such promise as a keyboard warrior . Your shipmates are so lucky.

The terminals are different in diameter. There is no such standard that calls for a 5/16" bolt or stud and that’s not ideal for the reasons Steamer mentioned. They’re common because they’re common on cheap cars, not because of some sort of standard, but thanks for displaying your ignorance.

i guess this satisfied my want …‘of new threads’ !!
lets not sour the atmosphere where a future topic may require cooperation!!

111 to defend the posting to this group saying that we all use light bulbs and therefore the posts are relevant to this group.

44 to ask what is a “FAQ”.
4 to say “didn’t we go through this already a short time ago?”
143 to say “do a Google search on light bulbs before posting questions about light bulbs”.
1 forum lurker to respond to the original post 6 months from now and start it all over again…


You forgot the forum moderator who finally shuts the topic down when it got too anal and divisive.

I reckon it ran its course but I’d like a few more pics of that project, maybe I’ll send in a topic photo next time things get slow.

Hmm… cars don’t typically have threaded studs on the batteries…
