Shared Vanagon Dictionary

• electrolyte

  In the lead-acid batteries discussed in Gerry’s battery FAQ, the liquid mixture of sulfuric acid and water in contact with the plates. Its density changes with charge state. This meaning is specific to that battery chemistry; it is not a generic name for every camper battery’s contents.

• Absorbed electrolyte

  Type of deep-cycle battery using absorbed electrolyte and recombinant technology

• Electrolyte level

  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.

• Flooded cell

  Battery design using liquid electrolyte and lead-antimony plates

• Gel cell

  Battery design using gel-type electrolyte and lead-calcium plates

• Specific gravity

  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.

• Hydrometer

  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.

• State-of-charge

  An estimate of how much charge remains in a battery, commonly expressed as a percentage of full charge. It differs from battery health: a worn battery can be fully charged yet store little usable energy. The voltage and electrolyte-density table in Gerry’s 1995 FAQ concerns lead-acid batteries, not a universal camper-battery gauge.
