The 18650 battery casing is made of high-quality environmentally friendly plastic, which is strong and durable.
These sleeves are very suitable for adding 18650 batteries, 18650 rechargeable batteries, and 18650 lithium ion batteries.
These are good replacement gaskets to use with the 18650 battery in the LED flashlight. The battery sleeve can center the 18650 battery in the flashlight.
Use these protective covers to change the 3 AAA battery holders in the TAC lamp to a 18650 rechargeable lithium ion battery.
Note: Before choosing a flashlight battery holder, please check the diameter of the sleeve before choosing, because the battery protection sleeve is not suitable for flashlights that use 26650 battery flashlights.
