How do you test a lead-acid battery?
The most accurate way to determine the state of charge of a lead-acid battery is to measure both the voltage and the specific gravity of the battery electrolyte. This gives you a holistic status of the battery. You use a voltmeter/multimeter to measure voltage and battery hydrometer to measure the specific gravity.
Can a voltmeter measure a lead acid battery?
Although a voltmeter is good for measuring the state of charge of a lead acid battery, it does not provide conclusive results. The most accurate way to determine the state of charge of a lead-acid battery is to measure both the voltage and the specific gravity of the battery electrolyte. This gives you a holistic status of the battery.
How does a battery test work?
When used regularly it can be used for tracking the battery’s health and actual capacity and estimate remaining life of the battery. During the test it is measured how much capacity (current x time expressed in Ah) the battery can deliver before the terminal voltage drops to the end of discharge voltage x number of cells.
