Are you looking for a trickle charger or a battery maintainer - there is a subtle difference ?

A battery charger is what you charge the battery with when it is flat (discharged) and usually means disconnecting the battery from the car and charging for several hours.

A battery maintainer lets you maintain a fully charged battery while the car hibernates for a prolonged period - it doesn't "charge" the battery, only maintains the voltage which is what I assume you mean....
Porsche have their own brand maintainer (expensive) and C-tec is a well regarded brand here in Australia
