Battery removal/charging

[DCMan]

Hi all

I've got a 2002 Saxo which is still going strong. I've been away for a while and haven't driven it for a few weeks and the battery is dead.

I've got a battery charger, but I was just wondering if I need to know anything before I remove the battery for an extended period of time? Am I going to clear any codes etc? (Apart from the radio code which isn't an issue). I'm more thinking along the lines of immobilisers etc.

Thanks

just the radio code

Nice, thanks.
