> Consumers do not know the amp-hour capacity of coin cells or AAA batteries. They don't know and they don't care. Consumers put a coin cell into an AirTag and come back a year later to replace it when their iPhone tells them to.
Then why label batteries with a capacity at all, if consumers don't care so much?
They care when they're buying batteries and they have a choice of different ones to buy.
> It is not more convenient, since consumers do not think about <1Ah values, virtually ever.
Even if that were true, it doesn't justify changing the customary unit.
> And I repeat: We could represent all distances in millimeters just in case, but we don't.
> LA is only 4506163000 millimeters from NYC. Very convenient.
And people could report their height in meters, yet they frequently use centimeters.
Among other things, we don't use millimeters for long distances because 10-digit numbers tend to be an awkward number of digits to work with, but 4 or 5 digits are still pretty easy and natural to work with. I wonder how many digits the LA to NYC distance is in kilometers? Well, wouldn't you know it, it's 4.
Anyway, this conversation isn't going anywhere. Batteries will continue to be labeled in mAh, even if you have a strong personal opinion that everyone else is using the wrong prefix thousands of companies and millions of people just need to switch to Ah now.
We label batteries with capacity in cases where said capacity is tiny compared to user's needs. It allows user to guesstimate if their phone will last 1 or 2 days on a single charge.
For AAA batteries, which in typical use last at least several months the exact capacity number becomes largely irrelevant.
