The kWh (kilowatt-hour) capacity of a lead-acid battery is a measure of the energy storage capability, reflecting how much energy the battery can provide over time. This capacity can vary widely based on the battery''s size and design, typically ranging from hundreds to thousands of kWh.
Battery capacity falls by about 1% per degree below about 20°C. However, high temperatures are not ideal for batteries either as these accelerate aging, self-discharge and electrolyte usage.
Maintaining Your Lead-Acid Battery. Lead-acid batteries can last anywhere between three and 10 years depending on the manufacturer, use and maintenance. To get the most life out of your battery: Don''t let your battery discharge below 20%. Don''t overcharge your battery.
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.

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
Figure 3: Charging of Lead Acid Battery. As we have already explained, when the cell is completely discharged, the anode and cathode both transform into PbSO 4 (which is whitish in colour). During the charging process, a positive external voltage is applied to the anode of the battery and negative voltage is applied at the cathode as shown in Fig. 3. Due to the
This article examines lead-acid battery basics, including equivalent circuits, storage capacity and efficiency, and system sizing. Stand-alone systems that utilize intermittent resources such as wind and solar
Usually the unit of battery capacity is ampere-hous (Ah) or milliampere-hours (mAh) for small batteries. T he unit of measurement itself shows that battery capacity is the product of constant current flowing through the load connected to a battery (in amps or in milliamps) and the discharge time in (hours). 2.

Capacity. A battery''s capacity measures how much energy can be stored (and eventually discharged) by the battery. While capacity numbers vary between battery models and manufacturers, lithium-ion battery technology has been well-proven to have a significantly higher energy density than lead acid batteries.
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.
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
Lead acid batteries typically have coloumbic efficiencies of 85% and energy efficiencies in the order of 70%. Depending on which one of the above problems is of most concern for a particular application, appropriate modifications to the basic battery configuration improve battery performance.
According to a 2003 report entitled "Getting the Lead Out", by Environmental Defense and the Ecology Center of Ann Arbor, Michigan, the batteries of vehicles on the road contained an estimated 2,600,000 metric tons (2,600,000 long tons; 2,900,000 short tons) of lead. Some lead compounds are extremely toxic.
