Li-Ion Battery IQ - What is mAh?
You may have seen electronic device descriptions, especially for power banks, that include a milliamp hour or mAh, and wondered what does this mean? As indicated in the chart below, the mAh determines the battery power and helps determine watt hours too, an important measure for airline carry-on limitations. As a universal unit of measure, mAh is also referenced in some lithium-battery fire containment testing.
At HOT-STOP 'L', we always want to help you choose the right fire containment bag size for the types of devices you are bringing on board the plane. In some cases, we custom design and test containment kits to accommodate higher mAh or watt hour ranges. See the typical mAh range below for common personal devices and contact us with any questions.
Watt hours = (mAh x Voltage) / 1000
mAh = (Watt Hours x 1000) / Voltage
Standard nominal voltage for li-ion batteries is 3.7V but can be 6.5V or more
