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.
For lead acid batteries the rated capacity (i.e. the number of AH stamped on the side of the battery) is typically given for a 20 hour discharge rate. If you are discharging at a slow rate you will get the rated number of amp-hours out of them. However, at high discharge rates the capacity falls steeply.
A lead acid battery is made up of a number of cells. Each cell has a positive and negative plate, separated by an electrolyte. The number of cells in a lead acid battery depends on the voltage rating of the battery. For example, a 12-volt battery will have six cells, while a 24-volt battery will have twelve cells.
Because, when a 1C-rated battery is discharged faster than 1 hour, the losses become high, and the Ampere-hour ratio is not maintained. Lead Acid batteries are typically rated at 0.05C (20h). Which means they should be discharged over 20 hours or longer. The table below shows typical battery discharge rate specifications.
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.
Sulfation prevention remains the best course of action, by periodically fully charging the lead–acid batteries. A typical lead–acid battery contains a mixture with varying concentrations of water and acid.
Battery voltage, or state of charge (SOC), of a lead-acid battery can be estimated by measuring the open (no load) battery terminal voltage using a digital voltmeter. Prior to measuring, the …
The number of cells in a lead acid battery depends on the voltage rating of the battery. For example, a 12-volt battery will have six cells, while a 24-volt battery will have …
About 60% of the weight of an automotive-type lead–acid battery rated around 60 A·h is lead or internal parts made of lead; the balance is electrolyte, separators, and the case. [8] For …

The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o…
