No, there’s no “per” in mAh.
oerpi@discuss.tchncs.de 1 month ago
Of course there is, miliAmp per(e) hour,duh.

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

That sounds nice for appliances that run intermittently like refrigerators
MangoPenguin@lemmy.blahaj.zone 1 month ago
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 there first error with units. (Procedes to google “verizon dollars and cents”)

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.
Ilovethebomb@sh.itjust.works 1 month ago
Acre-feet as a unit of volume is one I’ve heard before.
Absolutely cursed unit.

Furlongs per fortnite, but its talking about the file size of the uncompiled source code of the current version.

mA / h / h = mAh / h^2
That’s one hell of a measurement unit.
Revan343@lemmy.ca 1 month ago
mAh ≠ mA/h
hoshikarakitaridia@lemmy.world 1 month ago
So it would be
mAh / h => mA
Then?
Siethron@lemmy.world 1 month ago
It’s got a constant rate of frequency acceleration?
themaninblack@lemmy.world 1 month ago
So this is 510 mA per hour, I guess
Naich@lemmings.world 1 month ago
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.
Nikls94@lemmy.world 1 month ago
The battery has the storage capacity to pass 510 mA in an hour. If you discharge at half the capacity (0.5C) it will be empty after 2 hours.
If it was to draw 51 mAh it would last 10 hours.
But if it would draw 1020 mAh it would only last 30 minutes
themaninblack@lemmy.world 1 month ago
This is the winning response I think.
ChaoticNeutralCzech@feddit.org 1 month ago
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.
themaninblack@lemmy.world 1 month ago
I get this is a battery but the units don’t make sense unless it’s going at 100% all the time

I'm particularly fond of kWh per year tbh: E/t•t/t

except there’s no ‘safe word’ when you’re dealing with the anal carnage from verizon.
