Load car battery conveniently via the cigarette lighter!

Yes, it actually works -and has been for 3 years over winter. In connection with the multi-cigarette lighter cable do I charge the car battery via the cigarette lighter. It could not be going: no fumbling, no dirty hands -just stuck in cigarette lighter and ready! Have permanently connected during the winter months the unit; Unit automatically switches to trickle charging. No problems with the battery, nor with the electronics of the vehicle.

So my tip:
Additional interesting definitely multi-cigarette lighter cable CTEK equal, thus charging via the cigarette lighter can be conveniently!
Important Note:
The store in this way only works if the cigarette lighter is connected to permanent plus, so also works with Zündungsaus!

Supplement v 15.04.2010.:
CTEK has in the meantime also a special charging cable provided above solution via the cigarette adapter wg. the lack of continuous current is not possible. This charging cable (cost 8 - 10 EURO) also has 3 LEDs that indicate a the battery state of charge and indicate when to be recharged again. The cable is permanently connected to the battery and is connected by means of plug-in system with the CTEK charger. Me is also a smart solution!
