What is the difference between W and Mah?
Choosing the right battery for your gadget can be tricky, so let’s clarify the difference between Wh (watt-hours) and mAh (milliampere-hours). These units measure different aspects of battery capacity, leading to confusion.
Wh (Watt-hours) measures the total energy a battery can deliver. Think of it like the total gas in your car’s tank. A 50 Wh battery can supply 50 watts of power for one hour, or 25 watts for two hours, and so on. This is a crucial metric for determining how long your device will run on a single charge.
mAh (milliampere-hours), on the other hand, measures the battery’s charge capacity at a specific voltage. It tells you how much current the battery can provide over time. Imagine it as the flow rate of the gas from your car’s tank. A higher mAh rating usually means longer runtime, but this is voltage-dependent. A battery with a higher mAh rating at a lower voltage might deliver less energy (Wh) than a battery with a lower mAh rating but a higher voltage.
- Key Difference: Wh is a measure of *energy*, while mAh is a measure of *charge*. Wh directly relates to runtime, considering both voltage and current. mAh only considers current.
- Important Note: You cannot directly convert mAh to Wh without knowing the voltage. The formula is: Wh = (mAh * V) / 1000, where V is the voltage in volts.
For example, a 5000 mAh battery at 3.7V has a capacity of approximately 18.5 Wh (5000mAh * 3.7V / 1000 = 18.5Wh). This means it can supply less energy compared to a 25 Wh battery operating at a higher voltage.
- Always check both Wh and mAh ratings when comparing batteries.
- Prioritize Wh for a clearer understanding of total energy capacity and runtime.
- Consider the device’s voltage to make an accurate comparison using mAh.
