The specific gravity of the electrolyte is directly proportional to the amount of acid in the electrolyte. The more acid in the electrolyte, the higher the specific gravity. Conversely, the less acid in the electrolyte, the lower the specific gravity. The specific gravity of a battery is also affected by the battery's state of charge.
