I have a 4 year old Sport that stands around in the garage most of the time just at the moment and I need to keep the battery charged......I am considering purchasing a CTER XS3600 charger which the makers are saying it can be hard wired to the battery terminals and all I would need to do is plug in the charger WHITHOUT TAKING OFF THE MAIN BATTERY LEADS - in the manual it states leads should be taken off before charging. Any advice would be welcomed....Andrew Andrew Kennedy
