Looking! (previous: CLS55)

charging battery using cigarette lighter adapter

Hi everyone, I have a CTEK battery charger with the cigarette lighter adapter (this is the same as the MB-branded unit). I can't seem to get my CLS55 to charge using the power port in the rear seat or trunk or the actual cigarette lighter in the ashtray. So, for right now, I've got the charger hooked up directly to the battery (using alligator clips). In the future, though, how do I charge the car in the "MB recommended" way? fwiw, the battery is virtually dead right now, I'm not sure if that's somehow affecting things (e.g., the power ports aren't active since the battery is already so low). For the charger to work, the ports need to be active...

Any comments appreciated!

I too had a dead battery when i charged thru the cigarette lighter...the dash was fully lit up but the engine refuses to turn.
