Understanding the Capacity and Performance of Large Lead Acid Batteries

The capacity of a lead acid battery, measured in amp-hours (Ah), represents its ability to deliver a constant current over a specific time. At its core, capacity is determined by the number and size of the battery''s plates, as well as the electrolyte concentration. As these parameters increase, so too does the battery''s ability to store

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 in 20 hours. If your

A practical understanding of lead acid batteries

The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them. The most important lesson here is this:

Lead–acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge. Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the electrodes disintegrate
