Lead–acid battery

When a lead–acid battery loses water, its acid concentration increases, increasing the corrosion rate of the plates significantly. AGM cells already have a high acid content in an attempt to lower the water loss rate and increase standby voltage, and this brings about shorter life compared to a lead–antimony flooded battery. If the open

Battery Acid Specific Gravity

A battery acid specific gravity is defined as "the ratio of the density of the battery acid, relative to water with which it would combine if mixed evenly" A standard solution is defined as "a solution that contains some number of grams of solute per liter of solvent." The battery acid is made up of sulfuric acid that is diluted with

Lead-Acid Batteries

There are several reasons for the widespread use of lead-acid batteries, such as their relatively low cost, ease of manufacture, and favorable electrochemical characteristics, such as high output current and good cycle life under controlled conditions.

Batteries: Electricity though chemical reactions

Wet cell batteries contain a liquid electrolyte. They can be either primary or secondary batteries. Due to the liquid nature of wet cells, insulator sheets are used to separate the anode and the cathode.
