A green battery for an easy everyday carry. This Hi*AF rechargeable vape battery comes in a fresh green color that's easy to spot, with a 510 thread connection. Screw on your favorite 510 cartridge and it's ready. Give it a full charge before first use, and recharge before it runs completely flat. Treat it like any lithium battery: store it somewhere cool and dry, and keep it away from keys and coins in your pocket. A quick swipe with a dry cotton swab keeps the connection clean.
