Replacement of Vehicle Battery

Reconnecting the Battery

IF THE BATTERY HAS BEEN ON BENCH CHARGE THE CELLS MAY BE GIVING OFF EXPLOSIVE HYDROGEN GAS. AVOID CREATING SPARKS, AND IF IN DOUBT COVER THE VENT PLUGS OR COVERS WITH A DAMP CLOTH.

Always make sure that all electrical systems are switched OFF before reconnecting the battery to avoid causing sparks or damage to sensitive electrical equipment.

Reconnect the battery positive lead first and the negative last, ensuring that there is a good electrical contact and the battery terminals are secure.

Restart the clock (where fitted) and set it to the correct time. Re - enter the radio receiver/cassette player/mini disc player and compact disc player key codes and preset frequencies, if known.

Following reconnection of the battery, carry out a Green ECM drive Cycle This will allow the power train control module to 're-learn' idle values.
