What is Ah?

Ah stands for Ampere-hour (often written as Ah). It’s a way to measure how much electricity a battery can hold and how long it can power something. Imagine you have a toy car that runs on a battery. If the battery has a higher Ah, it means it can make the car run for a longer time before needing to be recharged.

Think of it like a water tank. The bigger the tank, the more water it can hold. Similarly, a higher Ah means the battery can hold more power. For example, if you have two batteries—one with 2 Ah and another with 5 Ah—the 5 Ah battery will last longer when used in the same device.

So, when people talk about Ah, they’re talking about how long a battery can last while powering a device, like a phone, tablet, or even an electric car!
