Affective Capacity of a Lead Acid Battery

Factor Affective Capacity of a Lead Acid Battery Points : Factor Affective Capacity of a Lead Acid Battery 1. Rate of discharge Higher the rate of discharge smaller is the capacity. 2. Permissible final voltage per cell Lower is the final voltage on discharge, higher is the capacity. 3. Number of plates/element A 23 plates/element battery does have more capacity than that of a 19 plates element and so on. 4. Amount of active material Greater is the amount of active material on the plates larger is the capacity. 5. Operating temperature Within given limits of operating temperature a battery gives better capacity in Summer than in Winter. If the operating temperature crosses 43°C the battery can be permanently damaged. 6. Quantity of electrolyte If the level of electrolyte is not maintained properly the capacity decreases. 7. Age of battery The capacity fall with passage of working life of a given battery. 8. Specific gravity of the electrolyte A poor specific gravity reduces capacity of the battery.
