Concorde`s Parasitic Load Test Adaptor (PLTA)

Concorde Battery`s Parasitic Load Tester Adaptor (PLTA) used in conjunction with a digital multimeter (DMM) will measure the parasitic load on aircraft batteries when the master switch is off and the aircraft is inactive. The adaptor is designed to mate with a MS3509 style quick disconnect receptacle. The innovative PLTA was conceived and engineered in response to concerns in the aviation community about the effect of parasitic loads on battery capacity, state of charge, airworthiness and battery life.

  • A parasitic load is a small, continuous flow of DC current that takes power from the battery when the master switch is off
  • Depending on the magnitude of the parasitic load, the battery in an inactive aircraft may be depleted within weeks or even days
  • Measuring parasitic loads is easy to do by connecting Concorde`s PLTA between the battery receptacle and the aircraft mating plug then connecting the tip-jacks to a DMM
  • Repetitive deep discharges from parasitic drain will shorten the battery life and batteries deeply discharged in this manner may not be recoverable
  • If authorized by the aircraft manufacturer, disconnecting the battery from the battery plug when the aircraft is stored will eliminate the parasitic load
  • Rated for loads up to 10 amperes and equipped with a 10 amp fuse
  • How to measure parasitic load and calculate time to battery depletion are provided in Instruction Manual, Aircraft Battery Parasitic Load Test Adapter, Document No. 5-0409
