I’m beginning to realize just how important energy is to me in so many ways.  To run my devices, cars, microwave, refrigerator, myself and most importantly in Florida, where I live, an air conditioner.

Milliamp Hour (mAh)t Milliamps Hour (mAh) is important because it’s the easiest way to distinguish the strength or capacity of a battery. The higher the mAh, the longer the battery will last. Batteries with different mAh ratings are interchangeable. If your battery is rechargeable then the mAh rating is how long the battery will last per charge.

Milliamps Hour is 1/1000th of an Amp Hour, so a 1000mAh = 1.0Ah

Think of a car’s gas tank.  Voltage is how much gas is being used, and mAh is the size of the gas tank.  The bigger the gas tank (mAh) rating the longer the device will run. If your battery is rechargeable, then think of the gas tank as refillable (rechargeable).
