These battery insulation gaskets are designed for 18650, 21700, and 32650 lithium-ion cells. They provide a reliable barrier between the battery terminal and other components, helping to prevent short circuits in your battery packs.

Made from durable barley paper, these ring-shaped gaskets offer both insulation and cushioning. They are a simple but essential part for anyone building or repairing custom battery packs for electronics, power tools, or DIY projects.

Each gasket features a self-adhesive backing for easy, secure placement on the battery cell. This helps you work faster and more accurately, ensuring each cell is properly insulated before you connect them together.

Whether you are a hobbyist or a professional, these pads help you build safer and more reliable battery packs. They are a cost-effective solution for protecting your batteries and your devices.

Usage Scenario

Mark was repairing a cordless drill battery pack. The old insulation pads had worn out, leaving the battery terminals exposed. He used these barley paper gaskets to replace them. The self-adhesive backing let him place each pad quickly and accurately on the 18650 cells. After reassembling the pack, he felt confident the batteries were properly insulated and safe to use.

Micro Comparison

While some battery builders use plastic or fish paper insulation, barley paper offers a good balance of flexibility and insulating properties. These gaskets are a direct replacement for many standard insulation pads and their adhesive backing makes them easier to apply than non-adhesive alternatives.
