The 18650 Lithium Cell Insulating Adhesive Ring Pad (Pack of 20) is a set of insulating adhesive ring pads designed specifically for protecting the positive terminal of cylindrical 18650 lithium-ion battery cells. These small circular insulating rings are placed around the positive terminal of the battery to help prevent accidental electrical contact between the positive terminal and the surrounding metal battery casing. They are an important accessory for DIY battery pack assembly, battery maintenance, power-bank construction, and other lithium battery applications.
The insulating ring features a self-adhesive backing that helps keep it securely positioned on the top surface of the battery cell. The central opening allows the positive terminal to remain exposed for electrical connection, while the surrounding insulating material provides separation between the positive terminal and the conductive metal casing. This helps reduce the possibility of accidental short circuits during battery assembly and handling.
These adhesive insulating rings are particularly useful when building custom 18650 battery packs using spot-welding techniques. After installing the ring around the positive terminal, nickel strips can be spot-welded to the battery while the insulating ring helps maintain electrical isolation between the positive terminal and the outer cell casing. The rings can also be used when replacing damaged or worn insulating rings on suitable 18650 cells.
Designed for battery-pack builders, electronics technicians, hobbyists, robotics enthusiasts, DIY makers, and rechargeable battery users, the 18650 Lithium Cell Insulating Adhesive Ring Pad is suitable for battery packs, power banks, portable electronics, electric projects, robotics, RC applications, and other devices using cylindrical lithium-ion cells. The pack contains 20 insulating rings, providing enough pieces for multiple individual cells or battery-pack assemblies.
