How To Measure Battery Charge. How to Measure State-of-charge Voltage Method. Measuring the specific gravity SG of the battery electrolyte can provide the best measure of the batterys state of charge SOC.
124V 75. It measures the density of the liquid electrolyte by measuring its specific gravity. 122V 50.
The hydrometer offers an alternative to measuring SoC of flooded lead acid batteries.
A battery hydrometer is used to test the state of charge of a battery cell. For GelAGM battery the density cannot be measured to determine the charge state. 233V 20. Hopefully you remember that amp hours are a measure of electric charge Q the battery capacity.
