Explanation of Ampere-Hour (Ah)

?·?The term mAh stands for milliamp-hour. Now, the milliamp-hour rating of a battery gives a huge amount of information. It gives you a really good idea of the amount of time it will last. Before it is discharged and needs recharging. mAH of a Battery- Explained mAH Specification of a Battery- Explained The mAH specification of a battery stands for milliampere-hours. mAH is the amount of milliamperes which a battery can provide (to a circuit or device) for the amount of hours specified in its specification. What is the meaning of the “mAh” on my rechargeable batteries? The capacity of batteries is indicated as XXXX mAh (milliampere/hour). The formula for calculation is as follows.

Read about how a higher mAh can have a tremendous impact on the performance of electronics like digital cameras. Anyone who owns a digital camera — particularly one that takes AA batteries as its power supply — knows that they have the capacity to suck battery power like a vampire.

It is not uncommon for a digital camera to completely drain its batteries after just an hour of heavy use, which often comes at the most inopportune times, leaving you with no digital camera when you need it the most. If you rely on AA rechargeable batteries for your digital cameras, then the most important consideration is investing in rechargeable batteries with the right mAh.

Of course, if you have no idea what mAh is, then it might be a bit confusing to determine what level of mAh you need for digital camera, and why. So, it is easy to imagine that the higher the mAh on your AA rechargeable batteries , the higher performance for your digital camera. The good news is that, for the vast majority of digital cameras, they draw very little power when simply turned on — most cameras have idle currents of 1 mA.

And considering that these are commonplace operations on all digital cameras, you can begin to imagine why your rechargeable batteries drain so easily. Think of it this way: if the rating of your rechargeable batteries is mAh, then you can draw milliamps for 25 hours, or 50 milliamps for 50 hours etc. However, this would only be when a camera is in standby mode.
