Can I take the battery off without any alarm/immobilizer problems? mk3 clio

[rsvmad1]

car been sat for a few weeks and battery needs a charge (not insured so cant take it for a drive) if I take the battery off to charge it will it affect the alarm or immobilizer, last thing I want is immobilizer problems when I reconnect the battery! Thanks
