Porsche 997 battery charging

[hurricaneone]

Hi all,

So I finally fulfilled a dream and bought a 997 at the weekend (YAY)
The aim is to use the thing as a weekend driver, and so occasionally it will go a couple of weeks without use. The previous owner has said the car may not start after a few weeks idle And suggested I get a trickle charger.

I know next to nothing about these, so would appreciate any recommendations. It looks like there is a type that connects straight to the battery and youtube appears to have a few that connect via the cigarette lighter - is this correct? Any preferences?

Thanks in advance

Thanks,

Car is parked indoor (underground car park) approx 4 metres away from nearest charge point, in case that is relevant.
Is the idea to keep the car plugged in permanently, or is this just an ad hoc solution to start up the car when the battery is flat? The latter would be what I would prefer if possible.

Cheers and apols for basic questions!

Thanks for responses,

Yes car park is totally secure.
