Excerpt: We’ve tested a variety of terminal solutions, and the 2 Pair Battery Post Shims by Pure Lead Anode Cathode Sleeves stood out for their versatility. These universal adapter sleeves fit both positive and negative posts seamlessly, eliminating the need for separate hardware. The material is sturdy yet flexible, ensuring a snug grip on most battery terminals without stripping or damage. We particularly appreciated the dual functionality—it saved time and space in our toolbox. True to their "universal" claim, these sleeves adapted well to older cars with corroded posts, making cable connections safer and more secure. While they didn’t introduce groundbreaking tech, their reliability and all-in-one design make them a surprising standout in our testing. If you’re tired of juggling different terminal solutions, these are worth adding to your kit.
