Coin cell stored energy
Coin cell stored energy is the total electrical energy that can be delivered by a small, disc-shaped lithium battery before depletion.
Also known as: CR2032 stored energy, coin battery energy
How big is it?
2.43 kJ of energy
Defined nominal stored energy · derived specification
Typical recorded range: 2.2 kJ to 2.6 kJ.
A little perspective
Food kilocalorie is about 1.72 times larger on this measurement.
Food kilocalorie: A food kilocalorie is the energy needed to raise the temperature of one kilogram of water by one degree Celsius, used to express food energy.

Why this measurement?
Why we use 2.43 kJ
For comparison, this page uses defined nominal stored energy. The record labels the measurement derived specification; that status is retained wherever the value is compared. The recorded range is 2.2 kJ to 2.6 kJ.
