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.
Basically every Laptop manufacturer.
Primary Battery
3-cell, 54 Wh, ExpressCharge™ Capable, ExpressCharge™ Boost Capable
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
Ahstored 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.
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.
