About phone batteries: What is mAh?
Your phone’s battery is arguably the most important piece of hardware on the device, seeing as nothing can happen without it.
While it’s not necessary to have comprehensive knowledge of the chemistry that goes into making portable power possible, it’s at least useful to understand basic terminology, like mAh, to make a well-informed purchase.
Yeah, the spelling of mAh does look a little weird, so why is it this way? The A is capitalized because, under the International System of Units, “ampere” is always represented with a capital A.
The term mAh is an abbreviation for “milliampere hour,” and it’s a way to express the electrical capacity of smaller batteries. With larger batteries, like car batteries, we usually use ampere hours, or Ah. There are 1000 mAh in a single Ah.
