Principles of lead-acid battery. Lead-acid batteries use a lead dioxide (PbO 2) positive electrode, a lead (Pb) negative electrode, and dilute sulfuric acid (H 2SO 4) electrolyte (with a specific gravity of about 1.30 and a concentration of about 40%). When the battery discharges, the positive and negative electrodes turn into lead sulfate (PbSO
Now, let''s interpret our reading. Note the number on the scale where the electrolyte meets the float. This number represents the specific gravity of the electrolyte in the battery. A higher specific gravity indicates a higher charge state. A fully charged battery should have a specific gravity between 1.265 and 1.299.
As you can see, consistently discharging a lead acid battery to 100% can severely shorten its lifespan. What is the float voltage of a 12V lead acid battery? The float voltage of a sealed 12V lead acid battery is usually 13.6 volts ± 0.2 volts. The float voltage of a flooded 12V lead acid battery is usually 13.5 volts.
For most lead-acid batteries, a fully charged battery will have a specific gravity reading between 1.265 and 1.299. However, it''s important to note that the specific gravity of a battery''s electrolyte will vary depending on the temperature and age of the battery.
The concentration of sulphuric acid in solution therefore provides a convenient manner to assess the state of the battery. Specific gravity is defined as the ratio of density of any fluid to that of water at 4°C.
