What are the advantages and disadvantages of lead-acid batteries?
Lead-acid batteries have been a cornerstone in energy storage for over a century. Understanding their advantages and disadvantages can help users make informed decisions. Cost-Effectiveness: Lead-acid batteries are generally cheaper to manufacture and purchase compared to other battery types, making them accessible for many applications.
What is battery acid / specific gravity?
The term “battery acid” refers to the electrolyte used in batteries. For lead acid batteries this is sulfuric acid (H 2 SO 4). Sulfuric acid is colorless, odorless, and strongly acidic. Why measure the density / specific gravity of battery acid? Knowing the specific gravity of the electrolyte in batteries gives insight into the level of charge.
How does temperature affect a lead-acid battery?
The electrolyte solution in a lead-acid battery expands when warm and contracts when cold. This affects the density and specific gravity of the electrolyte. Hydrometers measure the specific gravity of the electrolyte to determine the state of charge. And changes in temperature can alter our results.
Why do batteries have a specific gravity?
Knowing the specific gravity of the electrolyte in batteries gives insight into the level of charge. Due to chemical reactions during discharge, the density of the sulfuric acid electrolyte (or its specific gravity) decreases.
What happens if the specific gravity of a battery is low?
Overall the specific gravity of the battery will also be low. The damage to the cell maybe as a result of foreign debris in the cell, e.g. a metal strip that will react with sulfuric acid to form sulfates there by reducing the concentration of sulfuric and as a result lowering of specific gravity of the solution. 5.
What is a flooded lead acid battery?
Flooded lead acid batteries contain a liquid acid solution that is critical to the battery’s performance. The acid concentration is determined with a tool called a hydrometer; the hydrometer measures density, or specific gravity. Specific gravity (SG) is very important because it’s the most direct indicator of battery state of charge.

The result is typically converted into the right temperature and displayed in the desired unit like SG (Specific Gravity) 80/80 on the digital display.
How To Calculate Battery Specific Gravity?
However, we can make an educated guess by using the known specific gravity of a lead acid battery. Lead acid batteries have a specific gravity of 1.280-1.300. This means that they are 12.8-13% heavier than water. Therefore, a fully charged lead acid battery would have a specific gravity of 1.296-1.308.
