Ok, I rushed back with my take away last night and left my lights on. I've basically disconnected the battery (both terminals) and have it on charge.
Will I encounter any problems once I reconnect? Like radio code.

Thanks in advance

Jim

I disconnected the battery once for 20 minutes. It cleared all the radio stations ect.. but never asked for a code.

No radio code is necessary. If the battery is disconnected long enough you may lose radio / sat radio presets and, more annoying if you have PTI and used the voice recognition to painstakingly record contact names and phone numbers, any info recorded in the VR system. Stuff such as satnav address book is not wiped out with a battery disconnect, however.
