The term mAh stands for milliampere-hour, which is a unit of measurement for electrical charge. It indicates the amount of energy a battery can hold and deliver over time. To put it simply: A mAh rating tells you how long a battery can power a device before it needs to be recharged.
As you know, mAh measures the battery capacity. It means that a battery with a higher mAh rating can hold more charge, and thus, it can power a device for longer. Apart from battery mAh, there are a couple of other factors that affect the battery life. They include the usage patterns, battery age, and power consumption of the device.
A good mAh for a battery depends on the battery and electronics they are embedded into. For example, a power bank is considered to have a good battery capacity if it has 12,000 mAh.
The higher the mAh, the larger the battery capacity and the longer the device can run. For example, a smartphone battery with 3,000 mAh means it can provide 3,000 milliamps of power for one hour. Similarly, a power bank with 10,000 mAh can recharge a 3,000 mAh phone battery approximately three times (allowing for some energy loss).
The 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.
The significance of mAh stems from the relationship between capacity and usage. For example, if a device requires 100 milliamperes (mA) of current, a 2000 mAh battery should theoretically last 20 hours (2000 mAh divided by 100 mA). If a device has a low mAh battery, it may need frequent recharging, which can be inconvenient.
Calculate Cost of Battery Charge
Example of a small battery: the battery of a smartphone has a capacity of 2420 milliampere hours (mAh) and a voltage of 3.8 volts. This means that the battery size is 9.2 watt hours (Wh). With an electricity price of 30 cents per kilowatt hour (kWh), a charge of 80 percent costs less than a quarter of a cent.
