What Is Battery mAh and What Does It Measure?
In today’s world, where our gadgets are an integral part of our lives, we often come across discussions around battery ‘mAh’ or milliampere-hour. It is a common term for anyone who uses a smartphone, tablet, or any other electronic device. mAh is used to measure the battery capacity and battery life of any device. It is an important aspect to consider while buying a gadget since it directly affects the battery life of the device.
To begin with, let’s break down the term ‘mAh.’ An ampere-hour (Ah) is a unit of electric charge, and it is used to measure the amount of charge a battery can deliver. The ‘milliampere-hour’ (mAh) is a smaller unit of the Ah. One Ah is equal to 1000 mAh. Therefore, when we say that a battery has a capacity of 2000 mAh, we mean it has a capacity of 2 Ah.
The mAh rating is an indication of how much current the battery can supply for a particular duration of time. It measures the battery’s ability to provide a certain amount of electric current for one hour. For example, a battery with a capacity of 2000 mAh can deliver 2 amperes of current for one hour. Similarly, a battery with a capacity of 3000 mAh can deliver 3 amperes of current for one hour.
Therefore, the higher the mAh rating, the longer the battery life of the device. A 4000 mAh battery will deliver more battery life than a 3000 mAh battery for the same device. However, it is essential to consider other factors like the device’s size, screen resolution, processor, and other features that may affect the battery life.
The mAh rating is also an essential aspect to consider while comparing batteries of different devices. It helps to know which device has a better battery life. It is important to remember that the mAh rating is not the only factor that determines the battery life of the device. The device’s usage, age of the battery, and other conditions like temperature can also affect the battery life.
