Panasonic NCR18650B (Unprotected, Button-top)

21-DAY FULL REFUND POLICYAUTHENTIC GRADE-A BATTERIES GUARANTEE We've taken the Panasonic B, welded a button-top to the positive terminal, and shrink-wrapped an additional clear PVC around it. This makes the cell slightly longer, and allows it to work in additional devices. A button-top also makes the cell a little safer as it is harder to short-circuit, and easier to exchange between device and charger. Do you want a button-top, but not the Panasonic B? We can add protective circuitry and button-tops to any of our cells. Just send us a message.  Button-tops are ideal for flashlight users.
