I have 2k Accord and 04 Civic same issues. Without spacers in their battery's "Positive" terminals, built-up corrosion prevents starting in Wisconsin's cold Winter. I cut 1/2" copper pipe height-wise and in-half. polished the 2 pieces up and tapped them to form the terminal's general contour. The post clamp will do the rest for the snug fit. 12 years of "solid juice" flow to the starter-motors and counting. Blush

Welcome but moved you post to be its own not on one from 2009! Please don't do that.

Spacers once available were sold made out of 'lead' were 100% what to do when lead terminals of batteries or lead cable ends were worn/cleaned enough or stretched to and part of servicing a battery or replacement troubles with fit usually cheap OE U-Bolts stink.

I suggest using proper full gauge quality replacement ends or whole cables when there's a failure to get them snug enough to be right with what is sold new today up to at least OE specs, some better.

If you leave lose shims of other anything despite copper being the best conductor of electricity IMO you are just patching the problem still and fine in a jam but fix it better for the long run. You've had good luck and probably fine but isn't for everyone to do that. You really don't want to tap too hard on a battery terminal either as it's directly connected to the guts inside and risk shorting it!

Keeping terminals greased periodically you don't have this problem even with the cheap junk new for many years now. Tricks are apt to mess up the next time they are removed so not suggested by me as said short of quick emergency till can be done properly asap. If a cable loses total connection while engine is running most vehicles are subject to nasty problems to be avoided,

I've uses part of a hose clamp to shim those battery cables before.
