A battery designed for repeated, prolonged discharge and recharge, rather than chiefly for the brief high current used to start an engine. In camper discussions this distinction helps explain a leisure battery’s role. “Deep-cycle” is a duty description, not permission to drain any battery completely; chemistry and manufacturer limits still matter.

English · source definition

The 12-volt battery supply used for camper electrical loads such as interior lighting, the water pump, and controls on the documented Vanagon Westfalia. Whether a particular vehicle has a separate auxiliary battery depends on its model and later modifications.

English · machine-assisted draft

A lead-acid battery sold as requiring reduced routine servicing, often with no user access for checking or topping up individual cells. The name does not mean that charge, terminals and overall condition need no attention. Gerry’s 1995 FAQ discusses this older automotive usage; it does not describe every modern sealed battery.

English · machine-assisted draft

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.

• chemistry

English · machine-assisted draft

An electrical load that continues drawing battery current when the vehicle is switched off. Gerry’s FAQ mentions clocks and other key-off equipment: some draw is intentional, while excessive draw reduces parked starting reserve. Camper appliances deliberately powered from a leisure battery should be distinguished from an unexplained starter-battery drain.

English · machine-assisted draft

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.

English · machine-assisted draft

A charger whose delivered current decreases as charging progresses. In Gerry’s lead-acid battery FAQ this contrasts with a constant-current charger. The term describes charging behaviour, not a guarantee of automatic shut-off or compatibility with a particular camper battery chemistry.

English · machine-assisted draft

Describes a lead-acid battery affected by persistent lead-sulfate deposits on its plates. Gerry’s FAQ associates this condition with prolonged discharged storage and reduced serviceability. This is different from corrosion visible on external terminals, and the label alone does not establish that a battery can be restored.

• battery
• condition

English · 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.

• maintenance

English · machine-assisted draft

Discharging a battery to a low state of charge. It does not necessarily mean zero charge or zero terminal voltage. In the lead-acid context of Gerry’s FAQ, repeated deep discharge can shorten useful life. A “deep-cycle” label does not remove the battery manufacturer’s discharge limits.

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.
