What CR2032 open circuit voltage is considered "dead"
What CR2032 open circuit voltage is considered "dead"
batteries
A fully discharged alkaline cell (nominal voltage 1.5 Volts) still retains a voltage of 0.9 to 1.0 Volts. Therefore, voltage threshold for measurement can be taken as any value above 1.0 Volts. Battery energy delivery capacity however would be limited by other factors: Internal resistance / electrode surface deterioration.

Do batteries lose voltage as they''re used up?
NiCd and NiMH have rather flat discharge curves after a short initial period. That means the open circuit voltage doesn''t drop much for most of the discharge cycle even as the stored energy is getting steadily lower. These batteries then show a rather steep falloff in voltage as the last 10% or so of energy is drained.

Solar Inverters and Voltage Drops
Normally, if you have a 20 amp AC circuit in a house it should be 12 gauge. At 100 feet you would want to jump up to 10 gauge to account for voltage drop. If you take a DC voltage at 20 volts at 20 amps 12-10 gauge is plenty at close range. At 100 feet you would need 4 gauge minimum but more like 2 gauge to account for voltage drop to be …
DOE Explains...Batteries | Department of Energy
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
