Specific gravity is a crucial indicator of the water to acid ratio in a lead acid battery. It directly affects the battery''s charging, discharging, and overall performance. Monitoring specific gravity helps identify any imbalances in the electrolyte, enabling timely adjustments to maintain optimal battery health.
Neither choice is perfectly accurate and specific gravity is going to vary based on temperature and the quality/purity of electrolyte in the water over the life of the battery. The fundamental change to a battery over it''s life is that the internal resistance of the battery increases and therefore the same level of chemical charge will end up ...
