The Federal Aviation Authority FAA has overriding authority for airline regulation in the USA. Airlines from other nations visiting America follow its policies as a matter of course. Hence FAA rules for which batteries may fly in the cabin with us are to all effects universal.
The Batteries the FAA Allows On Board
The Federal Aviation Authority currently allows alkaline dry cell batteries in carry-on luggage at the time of writing. This includes AA, AAA, C, D, 9-volt, and button-size cells.
Moreover we may also carry primary-use nickel cadmium and nickel metal hydride batteries with us. However, there are restrictions when it comes to lithium-ion batteries. The upper limit is 100-watt-hours per battery.
How to Calculate Watt-Hours per Lithium-Ion Battery
Calculating individual watt-hours per battery is simple. The information is on the battery case. Hence we multiply the volts (V) by the ampere-hours (Ah) to arrive at a result. If a battery records its energy rating in milli-amp hours, we divide by 1000 to get to its ampere-hours.
The FAA allows most AA, AAA, cell phone, camera, camcorder, and handheld game lithium-ion batteries per this calculation. And laptop computer batteries, personal digital assistant, and portable drill lithium-Ion batteries too.
If your device is anywhere near the 100-watt-hour limit per battery, we recommend seeking expert advice. However, the hurdles are lower for non-rechargeable lithium-metal batteries in cameras and other small personal devices. The limit is two grams of lithium per battery. Thus single use AA, AAA, 123, CR123A, CR1, CR2, CRV3, CR22, 2CR5, and flat round lithium button cells generally comply.
The FAA Regulations Regarding AGM Wet Batteries
We may take absorbed electrolyte batteries with us on the airplane, including AGM lead-acid batteries within limits. These thresholds are 12 volts, and not more that 100-watt hours. The batteries must also comply with a number of other FAA specifications. These are too numerous to mention here. Please call UPS Battery Center toll free at 1-888-755-7718 concerning the lead-acid batteries you may carry on board.
