Another way: • Watt-hour (W•h): unit of energy (E or W). The joule (J) is also another unit for energy. • Ampere-hour (A•h): unit of electric charge (Q). The coulomb (C) is also another unit for charge.
Yes, exactly. I found it peculiar to invent new units for quantification of both energy and numbers of electrons. You assume the charge and discharge cycles occur at a fixed voltage throughout, and with that assumption you convert one to the other by multiplying by voltage. But is reinvention of new units worth the conceptual gap in understanding? Is it that hard to say 'kilocoulombs', or kilojoules?
I think is because he is considering a full battery charging cycle as unit of measure. So you need 60Wh to fully charge the battery. Of course, you can't throw that energy in 1 hour in your battery cause you will burn it, so you have to "spread" it on a 4 hour cycle.

The world's best teacher thanks
That is a nice thing to hear, thank you Kabanda!
This is a great video. You made it easy to understand. Thanks for making it.
You're very welcome!
Very much appreciated Jesse
Thanks Emelia, you are welcome!
Easy to understand as usual. Thank you
I work as a design engineer for a battery company. I work with stationary lead acid. Any advise for my career? Thanks
Great video
Thanks!

Excellent! Thank you for your contribution Alejandro.

Where did the 4 hrs come from? We were only looking 1 hr.
The phone is charging for 4 hours.
