This article describes the technical specifications parameters of lead-acid batteries. This article uses the Eastman Tall Tubular Conventional Battery (lead-acid) specifications as an example. Battery Specified Capacity Test @ 27 °C and 10.5V The most important aspect of a battery is its C-rating.
So for example, a lead acid battery might have a capacity of 600Ah at a discharge current of 6A. With a higher discharge current, of say 40A, the capacity might fall to 400Ah. In other words, by increasing the discharge current by a factor of about 7, the overall capacity of the battery has fallen by 33%.
Although this varies cycle to cycle, the maximum depth of discharge for lead acid batteries is typically at or below 50%. The cycle life of lead acid batteries is highly dependent on the State of Charge (SoC) that the battery is cycled at.
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.
The lead acid battery maintains a strong foothold as being rugged and reliable at a cost that is lower than most other chemistries. The global market of lead acid is still growing but other systems are making inroads. Lead acid works best for standby applications that require few deep-discharge cycles and the starter battery fits this duty well.
Discharge rate can usually exceed charge rate if required. Recommended operating range 10 to 25°C. Lead acid batteries are highly affected by temperature. The lifetime of lead acid batteries is cut in half for every 10°C rise in operating temperature over 25°C, due to rapid increases in the corrosion rate of the internal components of the battery.
A lead–acid battery''s nominal voltage is 2.2 V for each cell. For a single cell, the voltage can range from 1.8 V loaded at full discharge, to 2.10 V in an open circuit at full charge.
Nominal Voltage: The nominal voltage of lead-acid batteries is typically 2V, 6V, or 12V. It refers to the average voltage of the battery during charging and discharging processes and is used to identify the voltage level of …
