How to Find Watt-hour Rating for Lithium-ion Batteries

[@julianpereira8474]

The Wh rating of a lithium ion battery is not a measurement of how much energy (in Watts) the battery will expend over one hour. A Watt is one Joule per second. An hour is 3600s. One Wh is 3600 J. The Wh rating of a battery is a measure of how much energy is in the battery.

Exactly right! 👍 On a related matter, I can't stand it when people (typically newscasters or KZbin content creators who obviously have no idea what they're talking about) talk about kilowatts as if that's a measure of energy, or "watts per hour", which is utterly meaningless. That really drives me nuts!
