Battery State of Charge (SOC)

How to measure battery State-of-Charge (SOC)

Essentially, battery state-of-charge (SOC) can be easily measured using an amp-hour meter, by voltage, or by specific gravity. Measuring SOC by voltage or specific gravity requires specialized knowledge and a great deal of care, so it is recommended that owners utilize amp-hour meters for all battery systems. An amp-hour meter is somewhat like a fuel gauge for batteries, providing all …
