The interior chargers on my 981 CS are only active for 20-30 mins after switching ignition off, so no good for plugging Ctek into. Mine is connected to the battery using the battery adapter, fed through so it comes out near the wiper blade. I tuck it away before pulling car out of garage.

I have just purchased a CTEK XS3.8 12v 7 Step Battery Charger from the club shop to see me over periods when the car will not be used.

I have seen a 12V cigar lighter socket in the armrest and the glove box, however this connecter did not come with the new charger but i see it can be obtained from Hamiltons if its best to connect it here?

Appreciate any advice from anyone using a similar charger on the best way to connect it, use it, and what to expect, as i don't want to damage anything by not using it correctly!

Thanks

I plug mine into the passenger footwell cigar lighter socket. Works perfectly. I always plug in and turn on before locking the car. Never had a problem with the socket turning off.

There are lots of reports of power outlets switching off but I have also successfully connected a CTEK to any of the three interior power outlets (not the USP port) and never had a problem. It seems to be one of those mysteries of the 981 which may simply be down to how ofter a car is used and how much spare juice the battery has before power management says "Verboten"

P.S. I now use permanent battery post connections simply because it is more convenient given mains power access.

I have the same problem with all interior lighters turning off after 30min to save energy. I purchased a CTEK MXS 5.0 Battery Charger for my 981 and had to end up connecting it directly to the battery as I could get any of the lighter to say on.

I plug mine into the centre console 12v socket and it works fine.

The manual suggests connecting to the positive post of the battery and the designated negative connector close to the wiper motor ? .

This I am told enables the ECU to see that the battery is being maintained ....

Hi, my first post having only picked my car up last week... but have a CTEK 3600 which I used to use with my 996 through the cigarette lighter - personally find that much more convenient than connecting to battery terminals. I've plugged it into the Cayman and it has worked just fine, moving to full charge in a few hours and maintaining it ever since.

 

[RichardDade]

Is that a 981 Cayman?, mine has 12 volt socket in the glove box and centre armrest, which do you use.

Some of the post suggest not to use the sockets and to correct to the battery!

 

[HarrytheHornet]

Hi Richard, yes it is a 981. It's the one in the glove box. Works perfectly well for me

 

[RichardDade]

I will give it a go, just need to purchase the 12 volt socket adaptor for the Ctek first as the kit did not include this.

Thanks Richard

Ctek offer a lead with the male lighter plug fitted as an option, but it's cheaper just to purchase a plug from your local car accessory shop and modify the spare eyelet lead included with

the charger kit.

[ul][*]BTW use of the sockets is time-limited when drawing off current so as to avoid flattening the battery, however this doesn't appear to be the case when inputting electrical current during charging - that's my experience anyway. [][/ul]Regards,

I've read a few posts on different forums about this in the last 24 hours. The general advice seems to be that any of the 3 internal sockets fitted to all 981s can be used (not sure about the 4th you get with the smokers pack). You're right that they cut of after 30 mins from turning the ignition off, but apparently NOT if there is a charger plugged in.

The important thing apparently is to ensure you plug the charger in within that 30 minute window. Then the socket remains live indefinitely. So as long as you plug the charger in soon after parking the vehicle you are fine. Where it would NOT work is if you plugged it in more than 30 mins after switching the ignition off.

Hope that helps
