Wh (watt-hours) is a unit of energy, which is the amount of work a battery can perform. On the other hand, mAh (milliamp-hours) is a measure of the current flow, indicating how much power a battery can provide over a specific period of time. It’s important to note that power (measured in watts) is not the same as energy (measured in Wh or mAh).
Power = Current * Voltage therefore: watt hours = amp hours * 3.7 V So if you have a battery with a mAh rating of 26.8 Ah then it has 99.16 Wh (26 * 3.7). (Assuming the cells are in parallel) You may be able to do a similar calculation on multiples of 3.7V.
When comparing battery capacity in terms of Wh and mAh, it’s essential to consider the specific power requirements of the device or application. Some devices may require a higher energy capacity (Wh) to operate efficiently, while others may rely more on power delivery (mAh) for optimal performance.
mAh, or milliampere-hours, measures the capacity of a battery. It indicates how much charge the battery can hold and for how long it can provide power. The higher the mAh rating, the longer the battery will last. On the other hand, Wh, or watt-hours, measures the actual power that a battery can deliver.
No, battery energy and mAh are not the same. Battery energy is measured in watt-hours (WH) and represents the total amount of energy a battery can store and deliver. It takes into account both the voltage and capacity of the battery. On the other hand, mAh (milliampere-hour) is a unit of current that tells you how much charge a battery can hold.
mAh is better for measuring the capacity of smaller, portable devices. WH is better for measuring the capacity of larger, power-hungry devices. When comparing batteries, it’s essential to consider both the mAh and WH ratings to get a comprehensive understanding of the battery’s capabilities.
Let us explain the difference between mAh and Wh for battery capacity and what makes one better than the other.
