So - during my motorcycle years, I had an Optimate, which I'd connect to each motorcycle for a couple of days every month - particularly during the winter months when usage was significantly reduced.
I was told this wasn't suitable for a car, and I acquired this CTEK unit, which seems to fulfil the same function.
I'm interested your views on whether the same sort of application is advised - my Roadster has a specific 'cigar lighter' socket under the instrument panel which I understand allows direct charging.
I'm having difficulty understanding whether there's any significant difference between the two units and more importantly whether there may be any drawbacks or risks associated with overcharging.

Many thanks!
