Which protection prevents interior lamps flattening the battery?

  • A.A voltage sensing circuit, which switches the lamps off when the battery falls below a defined state of charge
  • B.A timeout that extinguishes them after a period
  • C.A fuse, which opens if the lamps are left illuminated for longer than the period for which they are designed
  • D.None

Answer: B

A controller switches the lamps off after ten or twenty minutes to protect the battery. Voltage based load shedding genuinely is used by energy management systems, which makes the last option a real protective strategy. Naming what changes and what stays the same is the reliable route through questions of this shape. Reading the definition literally, rather than recalling a summary, avoids the usual confusion.
