As per the handbook, turn ignition on then off. Disconnect battery within 15 seconds. Loosen the terminals with a spanner first so as to make it easier to remove in those 15 secs. I've read that leaving the ignition on while removing it could well put an electrical spike across the ecu and other electrical ciruits and worse case senario trash them.
