All that's required is a salt and: battery.
List
- https://www.eevblog.com/forum/projects/coulomb-counter-ic-for-coin-cell-products/ - not many options for measuring current out of a coin cell, without drawing a notable amount of current.
Tips/Techniques
Cell vs. Battery
A bit of semantic nonsense, but technically a battery is made up of cells. https://www.eevblog.com/forum/projects/biggest-battery-capacity-for-22-x-22-mm-case/ - cell vs. battery (cell is a single, battery is a collection of cells)
Counterfeit Capacities Over 3.6mAh
3.5 or 3.6mah is the highest single 18650 cell you can buy. a couple amusing anecdotes.
NiCads/NiMH
Noise on Older Batteries
- https://www.eevblog.com/forum/metrology/diy-0-1-to-10hz-noise-amplifier/ -Page 3 or 4. nimh or nicads have more voltage noise as they reach EOL
