Manufacturers frequently specify the rated capacity of their batteries in ampere-hours at a specific discharge rate. For example, this means that a lead-acid battery rated for 200 Ah (for a 10
AI Customer ServiceFor a lead-acid battery, the test time is approximated to be near the battery''s duty cycle. Most lead-acid batteries have a duty cycle of 5-8 hours and this is the timeline used
AI Customer ServiceAlthough the capacity of a lead acid battery is reduced at low temperature operation, high temperature operation increases the aging rate of the battery. Figure: Relationship between
AI Customer ServiceThe lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO 4 – → PbSO 4
AI Customer ServiceIt doesn''t stop there. It oxidizes the essential lignosulfonate that is present in the negative plates. This causes the negative active material to lose its porosity and the batteries
AI Customer ServiceAt present, the capacity of lead-acid batteries has the following labeling methods, such as C20, C10, C5, and C2, which respectively represent the actual capacity obtained when discharged at a discharge rate of 20h, 10h, 5h, and 2h.If it is
AI Customer ServiceBattery capacity is the total amount of electrical energy that a battery can deliver. Note however, that this is not volume over time, because a battery''s ability to perform reduces as it ages. We discuss lead-acid battery

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
AI Customer ServicePersonally, I always make sure that anything connected to a lead acid battery is properly fused. 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 capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert's law.
It turns out that the usable capacity of a lead acid battery depends on the applied load. Therefore, the stated capacity is actually the capacity at a certain load that would deplete the battery in 20 hours. This is concept of the C-rate. 1C is the theoretical one hour discharge rate based on the capacity.
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:
Myth: The worst thing you can do is overcharge a lead acid battery. Fact: The worst thing you can do is under-charge a lead acid battery. Regularly under-charging a battery will result in sulfation with permanent loss of capacity and plate corrosion rates upwards of 25x normal.
For example, this means that a lead-acid battery rated for 200 Ah (for a 10-hour rate) will deliver 20 amperes of current for 10 hours under standard temperature conditions (25C or 77F). Alternatively, a discharge rate may be specified by its charge rate or C-rate, which is expressed as a multiple of the rated capacity of the cell or battery.
