Why do batteries say mA and not A?

Why do batteries say mA and not A?
There are batteries in a smartphone there for 1000mA, 2000mA, 3000mA ... well, that is, where you can safely write down the abbreviated form 1A, 2A, 3A ...
Maybe there is a certain standard that requires you to specify A after a certain capacity?
What is the purpose of this?

Answer 1

for the coolness of the numbers.
marketers have found that the larger the number, the cooler it seems.
so a 3000mAh battery will always look cooler and more powerful than a 3Ah battery. even purely visually, 3 AH is lost in the text, but for those who are ignorant of physics and in general, what's the difference.
that's why they would buy
if they could write numbers in microamps * hours.
how cool the number 3,000,000 MKACH will look on the price tag !!
Even the smart ones can't resist.
ps. capacity is written in "Amp * Hours". the unit "Ampere" is used to describe the current, it will not work to "store" it :)

Answer 2

Previously, the containers were simply smaller.

Answer 3

Yes, marketing first. Secondly, you were rightly told that it is not AMPERS, but AMPERS PER HOUR ... This is different. For clarity, here's another thing: 10000mA per hour, for example, take. This is equal to 1A per hour ... Allegedly, the manufacturer says that a current of 1Amp can flow for an hour with the help of this Akum. If this is a power bank, then of course it’s a complete lie. There are always figures overestimate, often 2 times.
