EN · 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.
An unexplained key-off draw may reduce the starter battery’s reserve.Attributed to vanagon_corpus_draftView source
