Editing Battery (section)

==S2 K-series Fitting==



The procedure is described in the Owners Handbook and is pretty self explanatory:

1.  Undo the retaining clamp at the base of the battery (6mm Allen key required), and slide the battery out of the retaining shoe so you have easy access to the terminals.  If you're doing this on your own - loosen the negative black earth cable nut slightly BUT DON'T DISCONNECT IT JUST YET.

2.  Turn all lights, radios, satnav etc equipment off.

3.  Turn the ignition off and wait about 10 seconds for the engine management system to settle down.

4.  '''DON'T''' arm the alarm or immobiliser

N.B. It is easier to undo the 12mm nut on the stud rather than attempt to undo the 10mm nut on the terminal

5.  Within 25 seconds of turning off the ignition (i.e. before the immobiliser/alarm kicks in), disconnect the negative black earth cable from the battery.  '''ALWAYS''' disconnect the black first.

6.  Disconnect the positive red cable from the battery.

7.  Swap the old battery out, transfer the terminal connectors to the new battery, put the new battery into the boot so you can work on it to reconnect the terminal cables.

8.  Connect the positive red cable to the new battery.

9.  Connect the negative black cable to the new battery (have the keyfob to hand just in case the alarm goes off).  '''ALWAYS''' reconnect the black last.

10.  Slide it back into the retaining shoe, refit the 6mm clamp.
