Free QuotemAh stands for milliampere-hour, a unit used to measure the energy capacity of batteries and power banks. It indicates how much charge a battery or power bank can hold
Free QuoteThe relationship between mAh and battery capacity is straightforward. A battery with a higher mAh can store more energy. For instance, a 2000 mAh battery can provide 2000 milliamperes of current for one hour or lesser current for a longer time. The mAh rating is vital for devices requiring sustained power, like smartphones and laptops.
A circuit may instead only need 380mA of current for operation. In this case, the battery supplies 380mA for 5 hours, since 380*5=1900. Or for other circuits, it can supply 190mA of current for 10 hours, since 190*10=1900. The product of the current consumed times the number of hours in use must equal to the mAH specification.
Think of a battery as an example. If that battery can maintain a current output of one milliamp for 1 hour, you could call it a 1 mAh battery. A milliamp is a tiny amount of power, so this battery wouldn't be very practical. Practically, we see mAh used in any electronic device with a battery, from phones to Bluetooth speakers.
My iPhone 12 Pro Max is on its third “3,687 mAh” battery. The rechargeable Eneloop AA battery in my mouse has “2,000 mAh minimum”. My PC's uninterruptible power supply (UPS) uses a “9,000 mAh” sealed lead-acid battery. Based on the mAh ratings, I should expect better iPhone battery life with two AA batteries (4,000 mAh vs. 3,687 mAh).
The SI unit to express stored electric charge is a coulomb (charge delivered by 1 amp for 1 second), but mAh (charge delivered by 1 milliamp for one hour) is the common unit for batteries. In fact, 1 mAh = 3.6 coulombs! Li-po battery layers. The chemicals between are what stores electric charge Charge capacity is different from energy capacity.
The mAH specification of a battery stands for milliampere-hours. mAH is the amount of milliamperes which a battery can provide (to a circuit or device) for the amount of hours specified in its specification. Thus, a battery if a mAH specification of 1900mAH can provide 1900mA (milliamperes) for 1 hour of time.
