I've used the cigarette lighter socket but now have an extension permanently connected to the battery and I leave cable in trunk when not charging.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

11 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

anyone got any info on trickle charging the battery through the sugared lighter in a 996 c4s . cheers

POST 4Original post

IIRC the 996 cigarette lighter socket isn't live with the ignition off, unlike the 997, so can't be used to trickle charge/condition the battery. However, I'm sure someone with better 996 knowledge than me will be along soon to confirm or put me straight!

POST 5Original post

Hi Guys I'm pretty sure that any post 2001 3.6 996.2 should have a permanently 'live' socket. The 996.1 is switch live only.

POST 6Original post

My 2003 C4S started first time this weekend after sitting for over 2 weeks. I had a trickle charger on it and the user manual confirmed the cigarette lighter could be used as it is permanently live. Regards

POST 7Original post

My 2002 Targa sits happy plugged into a Porsche trickle charger in via the cigarette lighter socket. Car is Weekend/hols only use & no probs in 5 years of ownership. Dave S

POST 8Original post

I use a ctek trickle charger and have no problems with starting after long periods. I highly recommend them. I've used the cigarette lighter socket but now have an extension permanently connected to the battery and I leave cable in trunk when not charging.

POST 9Original post

I also sit mine permanently attached to a trickle charger. Had too many slow starts and not starting. So I wired a plug socket next to the car with a RCD in it and it just sits on that. It's been fine ever since. I have mine to the battery though only difference.

POST 10Original post

May be worth a battery check as well - on a healthy battery I am usually OK for at least 2 weeks, crossing my fingers up to 3, but just about hanging in there, but pretty much no chance after that, particularly if its wintertime.....

POST 11Original post

CTEK 3.8 charger sits nicely against the spare wheel in the trunk and is permanently attached to my battery. Works like a charm. Can confirm that 996.2 cigarette lighter socket is permanently live, so you could use that too.

This is a source reference. Confirm exact model applicability in the original material.
