Is lithium battery allowed in hand luggage?

Can You Pack Your Lithium Battery in Your Carry-on?

Traveling with electronics is a necessity for many, and that often means packing lithium-ion batteries. But are those batteries allowed in your carry-on luggage? The good news is, yes, they are permitted, but with some important caveats.

Understanding Watt-Hour Limits:

The key factor in determining whether your lithium-ion battery is allowed in your carry-on is its watt-hour (Wh) rating. This rating tells you how much energy the battery can store. The rules are as follows:

• Under 100 Wh: Batteries with a rating under 100 Wh are generally allowed in carry-on luggage without any special approvals. This includes most common smartphone, laptop, and camera batteries.
• 100-160 Wh: Batteries in this range require airline approval before they can be carried on board. You will typically need to contact your airline directly to request permission and provide details about the battery.
• Over 160 Wh: Batteries with a rating exceeding 160 Wh are strictly prohibited from being carried on board an aircraft. These batteries must be shipped separately as cargo.

Finding Your Battery’s Watt-Hour Rating:

The watt-hour rating is usually printed on the battery itself or in the user manual. If you can’t find the rating, look for the voltage (V) and amp-hour (Ah) ratings on the battery. You can calculate the watt-hour rating using the following formula:

Wh = V x Ah

Example: A battery with a voltage of 12V and an amp-hour rating of 5Ah would have a watt-hour rating of 60Wh (12V x 5Ah = 60Wh).

Additional Safety Tips:

• Always carry spare batteries in your carry-on luggage. This is a good safety precaution in case your main battery fails.
• Protect batteries from damage. Use a protective case or pouch to avoid crushing or short-circuiting the batteries.
• Do not carry loose batteries in your pockets. This could lead to a fire hazard.
• Keep batteries away from heat and direct sunlight. Extreme temperatures can damage batteries.

Remember, these rules apply to lithium-ion batteries in general. Always check with your airline directly for the most up-to-date information on specific battery types and restrictions for your particular flight. By being aware of these rules and following safety guidelines, you can ensure a safe and enjoyable journey with your electronics.
