Newbie question so not sure if this is in the right section. I've got a 2002 1.9 diesel ghia. The battery was flat after standing in the cold for a few days so I got a jump start. Since then its been starting ok but does seem to struggle a little when its really cold. I'm going on holiday soon and the car will be standing for a week. Is it worth charging the battery up or replace it. Are there any top tips for taking the battery off and putting it back on as I don't want to damage the electronics by doing it incorrectly.
