Review: good part would buy again - it works good but but i just need it longer type my fault not the part i damage my battery but hey the parts are good just i was wrong
Review: Very convenient, very solid! - These work great if you need to add another wire or two to your side-post battery terminals! Now I don't recommend anyone doing this. But I did! I removed the side post battery out of one vehicle and put it in another vehicle to replace a dead TOP terminal battery. I did this hurriedly one morning in the dark trying desperately to get to work on time. I had to be careful not to cross the polarity of the battery! Positive on one battery is on the other side of the other battery etc. I took some junk wire and quickly wrapped a bunch around the vehicle's battery terminal connectors and these wonderful side-post battery terminal bolts. The work was very sloppy, having been done in the dark and in haste! But the little 4 cylinder car started without hesitation! And guess what? I drove that way, everyday, for months! I never had a problem. Anyway, this testifies to the unique ability this product has to accommodate even the most ridiculous wiring situation a person can throw it's way! If you have a side-post battery, GET THESE!

### ⭐⭐⭐⭐⭐ Exactly what I was needing.
*by Z***Y on September 22, 2023*

Starting off these are priced so low. They are made from super conductive brass, so the performance is amazing. They fit snug and were universal on either end. So simple to install. I personally hand tightened them then used an appropriate wrench to give it a bit more. My side post battery was a nightmare in my second Gen Camaro. Using these gave me the room necessary to install the battery and the extra bolt for accessories is just a bonus. Highly recommend!
