Leading evidence: 'Use following charging regime' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, the most frequently mentioned possible cause is 'connecting the negative' (1 discussions; 0 report identifying it and 1 suggest it). The most frequently discussed action is 'Disconnect battery' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

I use the footwell socket too but the CTEK Lithium charger has a much thicker cable than the non-lithium charger and it feels very tight when you shut the door.

Suspected cause
I've wired up the battery connector to the positive on the battery and negative to the main earth on the bulkhead but I suspect connecting the negative to the neg on the battery would work the same.

Then you can couple/uncouple the terminal connectors with a quarter-turn of the battery nut instead of having to disconnect the battery

I also run the cable up to the rafters along the ceiling and down the wall to the charge as it's out of the way and much more visible and therefore avoids driving out of the garage with it all connected.

A tip I got from a US Porsche owners site - if you are going to use the CTEK battery connectors, use tin-snips to convert the eyelets to spade connectors.

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

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.

Looking to install a Ctek lithium charger for my 992 Carrera T. Following a thread on Rennlist I purchased the m6 eyelet extension cable with a vision of installing it so that I could charge without having to open the bonnet
Looks like this works for LHD cars but it’s too short for RHD.
How have you got yours wired in?
I have used the following charging regime on my
992s with lithium batteries
Connect via the footwell socket passenger side
but do not turn on at the mains.
Turn on ignition and wait 30/45 secs and then turn off ignition
Turn mains power on within one minute

It seems very inefficient!
Why just turning off engine once you’re inside your garage and plugging in on the socket doesn’t work?
Can’t believe Porsche can’t make these things as easy as on all other supercars.

Hmm how weird. I won’t ask how you figured this out! I did hear that the passenger side socket turns off after a given time.
Strange that Ctek don’t offer a longer cable
foresterlad said:
No argument on that point!
However using battery terminals requires using a remote sited earth and is hardly plug and go
Puzzled by this. Could you explain? It is just plug and go as far I know. Thanks.

Yea I had the same problem. I got the ctek extension cable for the end of it as it’s much thinner so fits under the door no problem

They do.
Halfords also sell these.
CTEK extension cable.
I found wriggling the lead to the front edge of the door fed through the gap with the wing bottom edge
Regarding the socket turning off power this is supposed to protect against unintentionally leaving a device connected which may drain the battery.
The procedure to avoid this first surfaced for me at a
Porsche club meeting
I have a 997 and bough some ctek extension leads and the ctek battery connect. I've wired up the battery connector to the positive on the battery and negative to the main earth on the bulkhead but I suspect connecting the negative to the neg on the battery would work the same.
I then poke the cable through the gap between the bonnet/scuttle and leave it connected in the garage. I also run the cable up to the rafters along the ceiling and down the wall to the charge as it's out of the way and much more visible and therefore avoids driving out of the garage with it all connected.
I have in the past used the passenger footwell socket without issue, I just found this more a hassle than the above method.
Good luck.

Similar, and I bought a Remove Before Flight banner from the space shuttle program (via eBay) just so that I don't forget to detach the charger cable before driving out

I like that!
