What is the specific gravity of a battery?
What is the specific gravity of a battery?
The specific gravity of the electrolyte in a fully charged cell should be from 1.280 to 1.300. If it varies more than 10 points above or below these values, adjust it by drawing off some of the electrolyte with a hydrometer and adding water to lower the gravity, or 1.400 acid to raise the gravity.
How do you find the specific gravity of a lead acid battery?
To check the specific gravity of the electrolyte, it is possible to use a hydrometer (also called an “aerometer”) or a digital density meter (also called a “digital hydrometer”). A lead acid battery hydrometer is a special type of hydrometer which looks like a syringe with a bulb.
What is the specific gravity of a 50% charged battery?
Check each individual battery cell. Specific gravity should not vary more than . 050 or “50”, points between cells….Battery School.
| State of Charge | Specific Gravity |
|---|---|
| 100% | 1.265 |
| 75% | 1.225 |
| 50% | 1.190 |
| 25% | 1.155 |
How is the specific gravity of a lead acid battery measured?
Since the electrolyte of a lead-acid battery consists of a mixture of water and sulfuric acid, the specific gravity of the electrolyte will fall between 1.000 and 1.835. Normally, the electrolyte for a battery is mixed such that the specific gravity is less than 1.350. Specific gravity is measured with a hydrometer.
What is the SOC of a lead acid battery?
A fully charged lead-acid cell has an electrolyte that is a 25% solution of sulfuric acid in water (specific gravity about 1.26). A fully discharged lead-acid cell has 12 Volt Lead Acid Battery State of Charge (SOC) vs. Voltage while under discharge
What is the pecific gravity of a battery electrolyte?
pecific Gravity of Battery Electrolyte Review One of the key parameters of battery operation is the specific gravity of the electrolyte. Specific gravity is the ratio of the weight of a solution to the weight of an equal volume of water at a specified temperature. Specific gravity is used as an indicator of the state of charge of a cell or battery.
What happens when a lead acid battery is discharged?
As the cells are discharged, the sulfate ions are bonded to the plates — sulfuric acid leaves the electrolyte. The process is reversed when the cell is recharged. A fully charged lead-acid cell has an electrolyte that is a 25% solution of sulfuric acid in water (specific gravity about 1.26). A fully discharged lead-acid cell has
