Lithium Vs. Lead Acid: Battery Capacity & Efficiency
Lead Acid Batteries Lose Capacity At High Discharge Rates. Peukert''s Law describes how lead acid battery capacity is affected by the rate at which the battery is discharged. As the discharge rate increases, the battery''s usable capacity decreases. A typical battery''s capacity is measured by the current that is required to fully discharge ...
Capacity is the leading health indicator of a battery, but estimating it on the fly is complex. The traditional charge/discharge/charge cycle is still the most dependable method to measure battery capacity. While portable batteries can be cycled relatively quickly, a full cycle on large lead acid batteries is not practical for capacity measurement.

Lead-Acid vs. Lithium-Ion: A Comparative Analysis of Battery
Lead-Acid Batteries: Energy Density: When comparing lithium-ion batteries to lead-acid batteries, lead-acid batteries typically have more energy density. This limits their capacity to store and deliver energy per unit of weight. Performance: While lead-acid batteries are reliable and provide sufficient power for many applications, they may exhibit lower …
When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte. The sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in Equation.
