Use these gaskets to fill the void in the tube while going from one battery size to another. No rattle. Each order is for a 10 pack of gaskets. Recommended to use 2 gaskets per a battery. 18650 >>> 21700 21700 >>> 26650 NOTE: These only help with the circumference of the battery. If your 18650 is truly 65mm this will probably not work. If it measures closer to 70mm it should work. Use at your own risk
