Does anyone know the Porsche OEM part number for the trickle charger for the '07 997TT?

I have an old unit from my 2000 C2 that plugs into the cigarette lighter. Wondering if that works for the 997TT.

Thanks.

 

Not sure about compatibility but this is the maintainer I use for my 11' C2.
Prt# 98061198100

 

I believe the older units were a DC converter and a long wire ending in the cig plug.
The newer one is a wire with a control unit in the middle, which selects between bike (!) and car and has leds to show full or half charge.

Both will do the job right, this is not too sophisticated a task. Stay with what you have, or look on ebay for a c-teck (or tech) charger which is the OEM version for less $. You will see from the auction pics what it looks like vs the one you have.
