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.
Most lead-acid batteries are constructed with the positive electrode (the anode) made from a lead-antimony alloy with lead (IV) oxide pressed into it, although batteries designed for maximum life use a lead-calcium alloy. The negative electrode (the cathode) is made from pure lead and both electrodes are immersed in sulphuric acid.
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.
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.
A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions take place at the electrodes:
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.

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 ...
We discuss lead-acid battery capacity specifically in this post, although what follows generally applies to all electrochemical cells. Battery capacity refers to what each cell …
The charging of lead-acid batteries can be hazardous. However, many workers may not see it that way since it is such a common activity in many workplaces. The two primary risks are from hydrogen gas formed when the battery is being charged and the sulfuric acid in the battery fluid. For general safety precautions when working with batteries, please see the OSH Answers …
Lead-acid batteries are usually charged by regulated DC voltage sources. This allows maximum accumulation of charge in the early part of recharging. NiCd Batteries NiCd vented batteries have a 1.2-volt nominal cell voltage. Occasional addition of distilled water is required to replace water loss due to overcharging in normal service. Cause of failure is usually shorting or weakening of …

In contrast, if a lead-acid battery has leaked, you''ll need a mild acid like vinegar or lemon juice (which contains citric acid) to neutralize the spill. Lead-acid batteries contain sulfuric acid, which is neutralized by a weaker acid. Safety precautions: Wear acid-resistant gloves and eye protection. Neutralization steps: Apply a mixture of vinegar or lemon juice …
Deep-cycle lead-acid batteries appropriate for energy storage applications are designed to withstand repeated discharges to 20 % and have cycle lifetimes of ∼2000, which …
We discuss lead-acid battery capacity specifically in this post, although what follows generally applies to all electrochemical cells. Battery capacity refers to what each cell can deliver, and this is of great importance to a battery user. We can imagine a battery having three compartments, although this is only a conceptual example:
Lead Acid Batteries Lead acid batteries from motor vehicles contain sulfuric acid and lead. Both are hazardous chemicals that can cause pollution to the environment and pose health and safety risks to humans. Sulfuric acid is corrosive and can burn the skin and eyes. Lead is soluble in water, especially in acidic conditions, and can easily reach groundwater through runoff. …
