20231210 · Effects of Sulfation and Acid Stratification. Sulfation occurs when lead sulfate crystals form on your battery''s plates, which usually happens if a battery is left undercharged or at a partial state of charge for an extended period. It hampers your battery''s ability to charge and discharge fully. Acid stratification describes the situation where the
2023913 · The truest measure of a battery''s state of charge is the specific gravity of the battery acid. The following shows the approximate state of charge at various specific gravities at 77ºF / 25ºC. Hydrometers can be difficult to use and at best accurate to +/-0.005 points. Voltage can be used to estimate state of charge but caution must be taken
2023923 · It is generally recommended to charge a sealed lead acid battery using a constant voltage-current limited charging method with a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast). For AGM sealed lead acid batteries, the ideal charging current is 25% of the battery capacity indicated by Ah (Ampere Hour).
