Tigerstew Posted December 1, 2023 Report Share Posted December 1, 2023 Hi guys Do you guys have any recommendations as in the brand and model on what trickle charger I would need for my boxster 981s here in the uk? Also when would a trickle charger need to be used? If the car is not going to driven for 2,3,4,5 weeks? And does anyone have a video on how to use and place the trickle charger onto the 981s? Thanks guys Quote Link to comment Share on other sites More sharing options...
greenman986s Posted December 1, 2023 Report Share Posted December 1, 2023 Ctek MXS 5.0 is the usual choice - you leave them connected whenever you are not using the car as they are a maintenance charger not a trickle charger Is your car kept in a garage or outside? 1 Quote Link to comment Share on other sites More sharing options...
iborguk Posted December 1, 2023 Report Share Posted December 1, 2023 I use a CTEK along with the optional comfort cable which allows connection to the car via a 12V accessory connection. The cable is thin enough you can shut the car door on it, if you present it to the bottom of the door. Quote Link to comment Share on other sites More sharing options...

It’s kept in a garage……do I just keep it connected to the car even if I’m not using it for say a month? Quote Link to comment Share on other sites More sharing options...

It won’t do any harm to keep your conditioner connected particularly in cold weather. Don’t connect the conditioner directly to the terminals on both sides of the battery (the manual explains how to do this) or you’ll bypass the “black box” that helps control the charging regime and do get a conditioner with an agm setting. I use a NOCO which I’ve found more reliable than the previous CTEK. Quote Link to comment Share on other sites More sharing options...
greenman986s Posted December 1, 2023 Report Share Posted December 1, 2023 Mine lives in the garage for 2-3 months over winter, permanently connected. I connected it straight to the battery terminals but i suspect the electronics on my 986 are less sophisticated.. Quote Link to comment Share on other sites More sharing options...

I don’t use the AGM setting on my CTEK 5.0 as it seems to throw up a red light. Instead I use the standard setting without any issues, which the manual says is fine to do. Also I have mine connected to battery and an earthing bolt on the n/s strut tower as per manual. People seem to have issues with the 12v connection in the car with car shutting it off after a period of time.

iborguk Posted December 2, 2023 Report Share Posted December 2, 2023 (edited) Either the normal or AGM setting can be used to charge AGM batteries, see the notes in the manual. I’ve used both settings , no issue. I default to the AGM setting. https://www.ctek.com/storage/5F698282EF11914E368ECD2BA726D2FC8F329CA0DA934C5E86A538F9AC089C23/00000000000000000000000000014050/pdf/media/b92f3bd538ed40b1bc345ee44e44d4fa/MXS_5.0-manual-low-UK-EN.pdf Using the 12v accessory port to charge won’t cause it to shut off, that’s a thing for devices drawing from the port after the car has been locked for a while , not charging via it.

daveg Posted December 2, 2023 Report Share Posted December 2, 2023 I've used an Optimate 4 connected directly to both terminals of the battery without any issues. At least I hope so! I've got a few of these chargers I use on motorbikes and have found them to be fine. No settings, all automatic. Quote Link to comment Share on other sites More sharing options...
Tigerstew Posted December 2, 2023 Author Report Share Posted December 2, 2023 Guys is this the right ctex one? it says ctek mxs 5.0 then a “t” as well, what’s the T mean? Is this the same as one you guys are talking about? https://www.halfords.com/motoring/battery-maintenance/battery-chargers/ctek-mxs-5.0-t-uk-battery-charger-665079.html?cm_mmc=Google+PLA-_-Motoring>Motoring+Products>Battery+Maintenance>Battery+Chargers-_-Motoring>Motoring+Products>Battery+Maintenance>Battery+Chargers-_-665079&srsltid=AfmBOorfsmiPTGhtmzoxBn-_tHgriUIqJM-CMOP3t45ayTLRwcNc7thpBaM Quote Link to comment Share on other sites More sharing options...
iborguk Posted December 2, 2023 Report Share Posted December 2, 2023 (edited) If you read the Halfords product link it says T for temperature monitoring/compensation. It’s the same as the one I linked and own. Edited December 2, 2023 by iborguk Quote Link to comment Share on other sites More sharing options...

Is it true that leaving it the footwell auxiliary socket will only last for a certain time before that socket shuts down and u have to connect it to the battery?

No, it will stay live if connected before the car the car shuts the socket down (a period of time after the doors are locked).

Not in my experience. It may be the case if you plug the CTEK in after the car has been parked up for a few hours it will not work, but again, I have not had this happen to me to the best of my memory.

moonshine Posted December 2, 2023 Report Share Posted December 2, 2023 (edited) I think the passenger footwell 12v socket shuts down 20 min after car shutdown unless a charge current is detected. If the charger is connected in the 20 min window, the 12v footwell socket stays live Edited December 2, 2023 by moonshine Quote Link to comment Share on other sites More sharing options...
Tigerstew Posted December 2, 2023 Author Report Share Posted December 2, 2023 Ohhhhh I get you guys, so basically plug it into the footwell socket as soon as u leave the car before it shuts down (20 mins) thanks Quote Link to comment Share on other sites More sharing options...

Green Genie Posted December 2, 2023 Report Share Posted December 2, 2023 I plug my CTEC into the socket under the armrest with the comfort connector each time I leave the car, never had a problem with it shutting down. I used to use the crocodile clips under the frunk the + to the positive side of the battery and - to the wiper linkage (it’s marked with a - symbol) as shown on this video https://youtu.be/KIaIw3M4dIo?si=ypsWCmaWsIsZnbZ9 but soon got bored 🥱 with taking the black plastic cover on and off. It would appear that some 981’s shut down the interior sockets after half an hour. My socket under the armrest stays live permanently it’s a late 2015 build. Hope this helps 😊 Quote Link to comment Share on other sites More sharing options...
