10 volts multiplied by 24 Amp-hours = 240 watt-hours.

Volts (V) x Amp-hours (Ah) = Watt-hours (Wh).

If the battery lists the Amp-hour rating, use this formula: The following formulas may be used to determine the watt-hours rating for a Lithium-ion battery: Some Li-ion batteries do not display the watt-hour rating on the battery label. Any spare batteries must be transported as carryon baggage with the battery terminals protected to prevent short circuit.

The battery’s size in watt-hours must be displayed on the battery, or the battery should be labeled with its voltage and amp-hour (or milliamp-hour) ratings to allow for size calculation (see formula below) if needed. A maximum of one spare battery not exceeding 300 Wh or two spares not exceeding 160 Wh each may be carried onboard. If the device utilizes two batteries, each battery cannot exceed 160 Wh. There is a single battery size limit of 300 watt-hours (Wh). The battery terminals must be protected from short circuit. If the battery is not securely attached, it must be removed and transported separately as carryon baggage.

When the Li-ion battery is securely attached and protected from short-circuit by being fully enclosed in the device’s battery housing, the battery may remain installed in the device and there is no limit to the battery size. If a mobility aid is powered by a lithium-ion battery, the device must be transported as checked baggage.
