Short Answer
Yes, you can usually bring lithium batteries on a plane, but with strict limits. Most airlines and aviation authorities allow small batteries in carry-on and checked bags, while larger batteries must stay in carry-on luggage. Always check your airline and the relevant authority before you travel.
Rules for Lithium Batteries
Common rules include limits on lithium content and watt-hour rating. Lithium metal batteries are typically limited to 2 grams of lithium per battery, while lithium-ion batteries are usually capped at 100 watt-hours. Batteries above 100 watt-hours may require airline approval, and spare batteries should be protected to prevent short circuits.
Safety Tips and Restrictions
Keep batteries in original packaging or a protective case, and avoid carrying damaged or recalled batteries. Devices with batteries should be turned off and protected from accidental activation. For detailed guidance, consult the official guidance from aviation safety authorities.
Summary
Travelers can generally bring lithium batteries on planes if they follow size and quantity limits, keep spares protected, and check specific airline policies. Confirming rules in advance helps avoid delays or issues at security checkpoints.
