Which requirement follows from fitting a stop start battery?

  • A.The charging voltage must be raised manually, which requires the regulator to be adjusted after the battery is fitted
  • B.No requirement
  • C.The battery must be charged fully before installation, which is required for every battery whatever its construction
  • D.The battery type and capacity must be registered with the vehicle

Answer: D

The energy management system tracks battery ageing and adapts its charging strategy, so a new battery must be registered with a scan tool. Omitting it leaves the system charging for the old battery's condition. Pre-charging is good practice in any case. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Tracing the requirement back to the physical constraint that produces it makes the answer follow. Checking the units of each quantity catches a wrong formula before the arithmetic begins.
