I am ONLY speaking from a consumer position and for those Wh is more useful.
The consumer looks on device a and on device b and then determines how often he can recharge its device. With Ah you cannot do this unless you know the Voltage, with Wh you can make this decision without any further knowledge.
Yes this does not include battery life or conversion of efficiency. But a cunsumer measures nothing he looks at the lable.
It is fine if you don’t understand electronics, but then don’t spit out misinformation.
Btw. no need to insult me. I have never put out misinformation, I may have not stated enough that I am viewing this as a consumer.
Please explain to me what the difference is between battery life if you have a 5000mAh battery and an 18Wh battery.
Please state the calculation that you would use to “determine how often you have to recharge” that is valid for Wh and not for Ah. I am all for it. If you can cite a single source where the manufacturer gives a specification that would give battery life in Wh, and not in Ah, I will concede the entire argument and say that you were right the whole time in every comment make a note that you were right. Please show your calculation work.
The thing is, it does not matter how much charge the battery holds, it does matter how much energy it holds. Without knowing the Voltage the Ah is useless.
This is patently, objectively misinformation and completely false. That is a direct quote of your words, today. That was your last comment. I have already laid out multiple examples of how Ah is a useful measurement and what you can do with it. Therefore, it is misinformation. It is not disinformation, but stating untrue things as fact is misinformation, even if you have no idea you are wrong.

Lol, you literally quoted me, didn’t actually read what you quoted, and then did something completely different.
Do you know that battery life ≠ battery capacity? That is not the same measurement as I have already tried to teach you 3 times.
Please state the calculation that you would use to “determine how often you have to recharge” that is valid for Wh and not for Ah.
What is its idle power draw? What is its power draw under load? Playing video? Sleep mode? That source gives nothing which determines battery life. All it gives is a nearly useless capacity number, just like all other manufacturers. So not valid at all. You still have exactly 0 more information about battery life.
If I am wrong, please state your calculations of what the battery life is with that 54Wh battery.
Your entire argument was “Ah is useless and Wh gives consumers the information to determine battery life” So go ahead, determine the battery life.
How is this any different at all if they said that it is a 5.8Ah battery? They don’t give any current or power draw.
As an exercise:
can you tell me the battery life difference between an arbitrary Laptop A with a 54Wh battery and Laptop B with a 27Wh battery?
Your entire argument was “Ah is useless and Wh gives consumers the information to determine battery life” So go ahead, determine the battery life.
Not quit sure where battery life is comming from, thats not my argument. To restate and also better phrase my argument:
Stored energy is the better measure for consumers for the quantification of the battery size in a consumer device compared to Ah stored charge.
Now i can cross compare devices based on that and do not have to worry about the Voltage of the battery of any other devices.
Please state the calculation that you would use to “determine how often you have to recharge” that is valid for Wh and not for Ah.
I never claimed that this is possible. I wrote “can recharge” not 'have to". I am referring to devices like a power bank which i can calculate with a simple:
powerbank has 100Wh and phone has 25Wh so 100/25=4
-> i can recharge my phone 4 times using that powerbank.

Basically every Laptop manufacturer.
