Specific gravity
Electrical systemsEnglish · machine-assisted draft
The ratio of a liquid’s density to that of water. In the flooded lead-acid battery context of Gerry’s FAQ, electrolyte specific gravity helps estimate charge and compare cells. It is different from electrolyte level; temperature and battery design affect interpretation. It is not a measurement for a sealed lithium camper battery.

Electrolyte level
Electrical systemsEnglish · machine-assisted draft
The height of the liquid electrolyte relative to the plates in a serviceable flooded lead-acid battery. It describes liquid quantity, not state of charge or specific gravity. Gerry’s battery FAQ discusses accessible cells; this term must not be read as an instruction to open a sealed battery.

Tools and maintenance terminologyEnglish · machine-assisted draft
An instrument that measures a liquid’s specific gravity. In Gerry’s battery FAQ it is used with electrolyte from accessible cells of a flooded lead-acid battery, helping compare cells and estimate charge. It does not measure voltage and is not a general-purpose tester for sealed or lithium camper batteries.
