Frequently Asked Questions

Safety FAQs

Common questions about safety resources and how they can help you choose and use your device.

Is it safe to leave my battery charging overnight?

Skip the overnight charge. Lithium cells run hottest at the top of a charge, and leaving one plugged in for hours adds heat and wear. Charge while you're awake and around, then pull it off the charger once it's full.

What should I do if a battery gets hot, swells, or leaks?

Stop using it right away, get it off the charger, and set it on something non-flammable. A swollen, hissing, or very hot cell has failed — don't puncture it or throw it in the trash. Let it cool and drop it at a battery recycling point.

How do I clean my device without damaging it?

Power down and let it cool first. Use isopropyl alcohol on a cotton swab for the chamber and mouthpiece, keep liquid away from the battery and charging port, and let every part dry fully before you reassemble.

Are loose 18650 batteries safe to carry in a pocket?

No — always use a battery case. A bare cell can short against keys or coins and vent. Carry spares in a hard plastic case, and retire any battery with torn wrap or a dented top.
