Wouldnt that just translate back to it drawing 510ma of current? If you use 510mah in an hour that means you are drawing 510ma of current. That also means for all day battery life you would need a 8000mah battery at least which would make quite the chunky watch lol.
Yeah, this seems like a metric specifically chosen s.t. it makes intuitive sense to the average person AND it has a nice physical interpretation. Similar to how EU efficiency labels show power draw in W as kWh per 1000h of use
510mA per hour is nonsensical because A is an instantaneous measurement. 510 mAh/h is 510 mA. I guess you need a backpack to carry the battery around if you want the watch to last all day.
The battery has the storage capacity to pass 510 mA in an hour. If you discharge at half the capacity of 255 mAh (0.5C) it will be empty after 2 hours.
If it was to draw 51 mAh (0.1C) it would last 10 hours.
But if it would draw 1020 mAh (2C) it would only last 30 minutes
Not really, it makes sense to give a max current. If a car's top speed is listed as 200 km per hour, it does not mean that it goes this fast continuously.
Really? I have a camera that is rated "3.7 V, 2 A" but only draws that amount from the battery when the flash capacitor is recharging. Yes, the normal current draw would be more helpful, and in case of a watch, the standby current.
This may be the charging current but it would be pretty unusual to pick a value slightly above what legacy USB can deliver (500 mA).
The max rating is important so your powersupply/battery can be sized accordingly. No powersupply can provide a abitrary current at their rated voltage.
except there's no 'safe word' when you're dealing with the anal carnage from verizon.
No, the safeword is "0.002 cents"
“Honey, can you come down to the bank? I need you to put in your PIN number at the ATM machine, as ASAP as possible!”
No, there's no "per" in mAh.
Of course there is, miliAmp per(e) hour,duh.
You got me there. Congrats.

That sounds nice for appliances that run intermittently like refrigerators
Yup, this is just saying 510mA in a weird way
How many MPG per gallon does it get per mile, though?
Give 'em a break, I'm sure it's just their first error with units. (Procedes to google "verizon dollars and cents")
their
Thanks.
Cursed units: https://www.youtube.com/watch?v=kkfIXUjkYqE
Furlongs per fortnight.
And an IRL one I encountered, and some one straight facedly expected me to do scientific research in this unit: The Miner's Inch.
Acre-feet as a unit of volume is one I've heard before.
Absolutely cursed unit.
Seems like a useful unit for measuring irrigation water.
Its usually on the purchasing side, and yeah, from that perspective it makes sense, especially in deficit irrigation scenarios.
I take far less issue with acre feet than I do with the miner's inch.
Or manure.
Or bullshit.
Furlongs per fortnite, but its talking about the file size of the uncompiled source code of the current version.
So this is 510 mA per hour, I guess. That or it just draws 510 mA continuously

This is the winning response I think.

I get this is a battery but the units don’t make sense unless it’s going at 100% all the time

It's got a constant rate of frequency acceleration?
Bros time traveling
I'm particularly fond of kWh per year tbh: E/t•t/t
mA / h / h => mAh / h^2^
That's one hell of a measurement unit.
Edith: apparently I'm an idiot
mAh ≠ mA/h
So it would be
mAh / h => mA
Then?
