I don’t use my 911 frequently over winter so it can be parked up weeks at a time. Would like to buy a trickle charge to look after the battery. Looking at the CTek . Any model in particular that gets recommended?

I assume the 12v are not live 24/7 as I have a dash cam plugged into the passenger footwell which automatically turns off then the 12v turns off which it does so after 20 minutes or so. Are all of them like this or are some live?

Finally with the ctek kit want to get the wired in kit so just assume connect one End to positive terminal and the other to the ground bolt?

Thanks

Use a CTEK MXS 5.0 on mine, via the 12v/cig socket in the centre console. It has multiple modes - Normal, AGP (for stop/start) and recon. Works fine.

I wasn't aware the one in the central arm rest was live 24/7.

Will get the CTEK and a 12v cig adapter

thanks

Yes I have a cig lighter adapter and works fine. A lot less hassle than trying to fish a wire from under the bonnet. thumbsup

I have an early 991.1 S and the only permanently live socket is in the side of the passenger footwell. Initially the sockets all stay powered after ignition is turned off but all the others switch off after a short time. Of course it may be different for later models - mine is one of the original 40 UK launch vehicles in 2011.

Have ordered the 12v adapter . All arriving today and will experiement with the sockets and hope one of them is permanent live.

Failing that will go for the battery connectors.

Do you guys leave it charged up weeks on end or give the battary a break inbetween?

CTEKs are designed to be left on all the time.

That makes life easier.

Planning to wash car, fill the tank connect up CTEK and put a winter cover on.

Anything else to do whilst it hibernates?

Will put it away from Dec to end of Feb.

Take it out every 3-4 weeks for a short run(avoid rain/salty roads if possible) and make sure it gets up to operating temp.
