I have the C-Tek multi XS4003 battery charger, and when it's on my 2010 Cayman, it starts the charging sequence ok, this is not from a discharged state, just when I am going to leave it for a few weeks.Its plugged into the central cig lighter.
After about 10 days or so, it enters the final stage of charging, the maintenance section, which I'm told can stay connected for many months, but after a few hours, the red error light comes up and it just sits there doing nothing.
The battery seems fine and has plenty of life for starting the car.
Any ideas?
Cheers
