How to check battery current using a multimeter. To accurately measure ...
Is a battery healthy if drops under 10 volts with load?
Bad Battery. A battery with one or more dead cells loses around 2.1 volts with each cell that has died. A battery with 1 dead cell therefore has a voltage of around 10.5 volts, 2 dead cells = 9.4 volts, etc. But usually once one cell goes bad the battery is replaced before others die as well.
Is My Lithium Battery Damaged? (Warning Signals Explained)
Low current. Lower capacity. ... their performance is affected by ambient temperature.

Yes, non-rechargeable Li batteries have a very flat discharge curve. Batteries in general don''t go all the way down to 0V when they die. There is some residual voltage, but the miniscule amount of reactive chemicals remaining can''t provide any meaningful amount of current, so the voltage drops precipitously if you try to draw current.
Ohm''s Law Calculator
Ohm''s law states that the current flows through a conductor at a rate that is proportional to the voltage between the ends of this conductor. In other words, the relationship between voltage and current is constant: I/V = const. The Ohm''s law formula can be used to calculate the resistance as the quotient of the voltage and current.
