21700 Battery Terminal Insulator Rings - Black - 20pcs

Very Good!!

They fit perfectly on my new cells very happy

There's usually not much to say about insulator rings but these are good enough to rave about. They are highly durable, look great and stay in place every wrap. I changed all my batteries to these once I found out how well they work and how durable they are. Good stuff!

Another perfect order! 18650 Battery Store Rocks. I'm so happy that I found this website after my other battery website went out of business. There batteries and supplies are at the same price point, but my other distributor had free shipping on orders over $50. That is the only difference between this site and my previous one. All products that I have received from 18650 Battery Store work great. Keep up sending me perfect orders and I will keep coming back!
