SOC Test:Measuring state-of-charge by voltage is simple, but it can be inaccurate because cell materials and temperature affect the voltage. The most blatant error of the voltage-based SoC occurs when disturbing a battery with a charge or discharge. The resulting agitation distorts the voltage and it no longer represents a correct SoC reference. To get accurate readings, the battery needs to rest in the open circuit state for at least four hours; battery manufacturers recommend 24 hours for lead acid. This makes the voltage-based SoC method impractical for a battery in active duty.

Battery state-of-charge can also be estimated with impedance spectroscopy using the Spectro™ complex modeling method.Voltage polarization and surface charge do not affect the reading as SoC is measured independently of voltage. This opens applications in automotive manufacturing where some batteries are discharged longer than others during testing and debugging and need charging before transit. Measuring SoC by impedance spectroscopy can also be used for load leveling systems where a battery is continuously under charge and discharge.

Battery Overcharge:Do Not Overcharge. Because of the characteristics of an AGM battery, too much of a boost charge, or overcharge will decrease the volume of electrolyte. The longer the overcharge time, the greater the drop in electrolyte and starting power. Because the battery is sealed, water can’t be added to make up the difference in the loss of electrolyte. In addition, overcharging can warp cell plates making future charging difficult or impossible. To prevent over charging, track charging times carefully, or ideally, use one of Yuasa’s automatic chargers. Always stop charging if the battery case becomes too hot to touch. Let it cool down 6 to 12 hours and resume charging. Charging times will vary depending on type of charger and the size of the battery.
