These work well, and can be trimmed if needed.The collar/clamp that attaches to the post on my battery was too big, even when all the way tightened, so I needed these. I put it on, but now the collar/clamp needed spread apart much more than it was, and I don’t have a spreader tool, but was able to use 2 wrenches to make it spread wider (there are videos on how to do this)… but now the bolt that tightens the collar/clamp is too short, because it’s wider - so now I have to find another, longer bolt that is the same diameter because the collar/clamp is threaded on one side. Most of my issues had nothing to do with these, just the awful design of my battery cable.Once I worked through all the drama, these worked great. Would be nice if there were a few different sizes or configurations for different issues. Not much to them, but they are priced fairly and much better than forcing a nail between your post and the clamp.

Ok, so the idea is that your battery post connector is too large. So, you can return the new battery, change the terminal post connector itself or fill the space with something between the post and the connector. Enter this product. Great idea. I imagine when the stars align it's a quick one, two and done. Put the product on the batt terminal, put the cable and connector onto the battery, tighten bolt, done. Happy user.The product did solve my issue in that I was stuck with a not tight enough connector on the battery. However, the inside diameter of the product would not match the battery's post diameter well enough to tighten it properly. Enter my tin snips, Cut a vertical slice in the adapter through into the top. Now there is a space to squeeze the now split adapter onto the post using the cable's connector to tighten everything. Worked fine in the end. It's been several months and all has remained tight.No arguments with the folks that made this product but what the @$#% has gone on with battery manufacturing? Used to be you bought a battery, it either fit the spot it was supposed to mount or not. The cables, zero issues. What's with this nonsense? I somehow get the feeling it's more non- USA product. I'd have no problem with that but let's stick to some kind of reasonable standards.

The caps come in 4 sizes numbered 1 (smallest) to 4 (largest) - number is stamped on the inside of the cap. There are many comments that they “do not fit.†True enough, the odds are not great that you will be able to just drop one on a post, tighten the clamp, and get on with your day. We would all love that, but I rarely get that lucky. Even the smallest one was too large for a 2009 Malibu I was working on. But, as you can see in my pics, they are easily cut, trimmed, tapped with a light hammer to form, and filed. Not sure what material these are made from, but they are very soft like tin or lead. Unlike some I’ve used that are a shiny “chrome†hard finish on a hard metal cap – those must fit the post almost perfectly and are more difficult to modify. I clamped an extended socket in the vise that is of the same diameter as the battery post to form the cap around with a very light weight hammer. With a pair of tin snips and a file, I was able to easily trim and smooth these caps. I first tried to cut up the sides and across the top so I could “fold it into itself†to be a smaller diameter (see pic) but it was still too thick to get the battery cable clamp around it. I settled with cutting the cap in half, filing sharp corners and any burrs, which made the needed thickness allowing me to tighten the clamp perfectly. Also, the cap was too long (stood above the post too high), but was very easy to trim shorter with the snips. I did NOT use the felt washer. (BTW, I hate, Hate, HATE these post clamps in the picture. I’ve struggled getting these tight on aftermarket batteries since they started putting them on cars at the factory many years ago!) In my opinion, half a cap looks more professional than wrapping tinfoil or shim stock, or jamming a few strands of copper wire around the post, and the cap is more likely to be reusable, unlike tinfoil and wire strands. Hope this helps some of you.
