What is a parasitic drain in electrical?

A parasitic drain in electrical systems refers to the unintended consumption of electrical current by components in a vehicle or device when it is turned off. This can occur due to faulty wiring, malfunctioning components, or devices that remain active, such as alarms or radiOS, leading to battery depletion over time. Identifying and addressing parasitic drains is essential to maintain battery health and ensure reliable operation. Regular checks can help prevent unexpected battery failures.
