The milliampere-hour (mAh) is a unit of electric charge that is commonly used to measure the capacity of batteries. It indicates how much current a battery can deliver over a specific period. For instance, a battery rated at 1000 mAh can theoretically provide 1000 milliamperes (mA) of current for one hour before it is fully discharged.
The milliampere-hour is part of the International System of Units (SI) and is derived from the ampere, which is the base unit of electric current. The symbol for milliampere-hour is mAh, where "milli" denotes a factor of one-thousandth. This standardization allows for consistent measurements across various applications, making it easier for users to understand battery capacities and performance.
The concept of measuring electric charge dates back to the early days of electricity. The milliampere-hour emerged as a practical unit in the 20th century, particularly with the rise of portable electronic devices. As technology advanced, the demand for efficient battery capacities increased, leading to the widespread adoption of mAh as a standard measurement in consumer electronics.
To illustrate how to use the milliampere-hour measurement, consider a smartphone battery rated at 3000 mAh. If the phone consumes 300 mA of current during usage, you can calculate the approximate usage time as follows:
[ \text{Usage Time (hours)} = \frac{\text{Battery Capacity (mAh)}}{\text{Current Consumption (mA)}} ] [ \text{Usage Time} = \frac{3000 \text{ mAh}}{300 \text{ mA}} = 10 \text{ hours} ]
The milliampere-hour is crucial for consumers when selecting batteries for devices such as smartphones, tablets, and laptops. Understanding mAh helps users gauge how long their devices can operate on a single charge, enabling informed decisions when purchasing or replacing batteries.

The ampere-hour (Ah) is a unit of electric charge that represents the amount of electric charge transferred by a steady current of one ampere flowing for one hour. It is commonly used to measure the capacity of batteries, indicating how long a battery can deliver a specific current before it is depleted.
The ampere-hour is standardized under the International System of Units (SI) and is derived from the ampere, which is the base unit of electric current. The relationship between ampere-hours and coulombs (the SI unit of electric charge) is defined as: 1 Ah = 3600 coulombs.
The concept of measuring electric charge dates back to the early days of electricity. The ampere-hour was introduced as a practical way to quantify battery capacity, allowing users to understand how long a battery can power a device. Over the years, advancements in battery technology have made the ampere-hour a crucial metric in various applications, from consumer electronics to electric vehicles.
To illustrate how to calculate ampere-hours, consider a battery that supplies a current of 2 amperes for 5 hours. The total charge in ampere-hours can be calculated as follows: [ \text{Total Charge (Ah)} = \text{Current (A)} \times \text{Time (h)} ] [ \text{Total Charge (Ah)} = 2 , \text{A} \times 5 , \text{h} = 10 , \text{Ah} ]
The ampere-hour is widely used in various fields, including:
To use the Ampere-Hour Converter Tool effectively, follow these steps:
What is an ampere-hour? An ampere-hour (Ah) is a unit of electric charge that indicates how much current a battery can supply over a specific period.
How do I convert ampere-hours to coulombs? To convert ampere-hours to coulombs, multiply the ampere-hour value by 3600 (since 1 Ah = 3600 coulombs).
What is the significance of ampere-hours in batteries? Ampere-hours indicate a battery's capacity, helping users understand how long it can power a device before needing a recharge.
Can I use the ampere-hour tool for different types of batteries? Yes, the ampere-hour tool is applicable for all types of batteries, including lead-acid, lithium-ion, and nickel-metal hydride.
How do I ensure optimal battery performance? To ensure optimal battery performance, regularly monitor charge levels, avoid deep discharges, and use the correct charger for your battery type.
