Battery mAh energy storage unit

What is a mAh battery?

mAh is a practical unit to measure the amount of electrical charge contained in a battery. It provides an estimation of how long a battery can power a device based on its capacity. While the SI unit for charge is coulombs, mAh is used in consumer electronics as it correlates more directly to battery life.

What is the mAh rating of a battery?

The mAh rating of a battery indicates its capacity to store and deliver electrical energy. mAh measures the flow of electrical current within a battery, reflecting its ability to provide power. mAh is extensively used to specify battery capacity in consumer electronics, such as smartphones, tablets, and other portable devices.

How many watts can a mAh battery last?

Usually, the capacity of lithium batteries cannot exceed 100 watt hours (Wh). But many rechargeable batteries are labeled in mAh units and can be quickly converted to mWh. Why do most batteries use mAh as their capacity rating?

What is Mah & how does it affect battery life?

mAh plays a crucial role in your device’s battery life more than you expect. In a simple explanation, the mAh rating indicates the device’s energy capacity. A higher mAh implies that the battery is capable of storing more energy. Consequently, it also means that your device has a longer operating time before requiring a recharge.
