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.

Doesn’t last long
The sunscreen itself is good it just doesn’t feel like you get what you pay for. Maybe 2 applications for my two kids and it was gone. I had another brand of the same size and got so many more uses out of it!

The best spray sunscreen
I use this in combo with coppertone defend and care with zinc sunscreen cream. It works awesome and prevents burns. I apply the cream first and use this for double duty on the spots that tend to burn fast. I used on my kids too and it keeps them from burning as well. It’s especially handy to spray on on your hand and pat into the hairline to keep the scalp from being burned and doesn’t leave the white residue cream does in the hair.

Awesome
It didn’t leave your hands all orange like some can. I get a pretty good color just putting on one so I only apply more to missed spots. No s smell either with this one! Last awhile!
