The relative density of a fully charged battery is typically around 1.28 to 1.3 for lead-acid batteries. This measurement can vary based on the type of battery and its specific composition.
No.AnswerPresumably, you mean 'specific gravity' or, as it is known these days, 'relative density'? If so, the relative density of a lead-acid cell or battery is, indeed, a guide to that battery's state of charge -that's why we use a hydrometer to check the condition of a lead-acid battery. However, it would be wrong to say that the relative density of a lead-acid battery 'effects' the voltage -it merely is a guide to the state of charge. (Actually, it's the state of a battery's charge that affects its relative density.)
Yes, that is true. As a battery discharges, the concentration of sulfuric acid in the electrolyte decreases, leading to a decrease in density or specific gravity. This change in electrolyte density can be used as an indicator of the state of charge of the battery.
density = mass / volume = 1.24 g/ml
The density of a battery can vary depending on its chemistry and design, but typical values range from 1.3 to 2.0 grams per cubic centimeter.
The electrolyte in a car battery is sulfuric acid, diluted with water. The density of the acid when fully charged is 1.265g/cm3. The chemical process, as the battery is discharged, makes the acid weaker and it becomes less dense. Down to 1.120g/cm3 when below 11volts.Checking the acid density will give you an idea of the state of charge.There are 6 cells in a 12v car battery. The charge of each cell should be the same. If the density is significantly different between cells, then that would indicate a fault in that cell and the battery is useless. Faulty cells may have distorted and shorted plates which would stop it being charged and show up with a different density than the other cells.
You think to lithium (Li).
Best Buy would be a good place to find a high density battery. If you cannot find on there, try radio shack.
It is called a hydrometer.Also, density equals mass divided by volume.See the Related Questions to the left for more information about hydrometer and density.yup
A magnesium air battery is more efficient than traditional battery technologies because it has a higher energy density and longer lifespan.
An AA battery will sink in water.
The specific capacity of the battery in this device refers to the amount of energy it can store per unit of weight or volume. It is a measure of the battery's energy density.
