What is a Lead-Acid Battery? Construction, Operation, and …
Lead-Acid Battery Specific Gravity. When a lead-acid battery is in a nearly discharged condition, the electrolyte is in its weakest state. Conversely, the electrolyte is at its strongest (or greatest density) when the battery is fully charged. The density of electrolyte related to the density of water is termed its specific gravity.
BU-403: Charging Lead Acid
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. ... Never add electrolyte as this would upset the specific gravity and promote corrosion. Watering …
Hydrometers and Specific Gravity
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. State of …

OverviewMeasuring the charge levelHistoryElectrochemistryVoltages for common usageConstructionApplicationsCycles
Because the electrolyte takes part in the charge-discharge reaction, this battery has one major advantage over other chemistries: it is relatively simple to determine the state of charge by merely measuring the specific gravity of the electrolyte; the specific gravity falls as the battery discharges. Some battery designs include a simple hydrometer using colored floating balls of differing density
