Hello

I ordered the CTEK MXS 5.0 battery charger and want to plug it into the cig lighter on my 2006 Cayman S. There Porsche Charge-o-mat is ridiculously expensive so I ordered a CTEK version. Does this work?

This one

Thank you for your help.

Ale_72

Yes.

I've been using "Battery Tender" chargers for years (cig lighter plugin configuration) with excellent results.

Thanks guys! The car has been sitting for four weeks without a drive, battery should be fine, right?

Ale_72

Best way to check it it trying turning the ignition on.

DBH

Yep. All should be okay.

What is the difference between the CTEK MXS 5.0 and the MUS 4.3? Anyone know?

Voyager6

I may be wrong, but the MXS is a 240VAC unit and the MUS is 120V. I just purchased and put into use a MUS 4.3 Polar unit on my Boxster.

thanks Will install it tomorrow. Do you use the regular "car" mode on the CTEK or sometimes the agm / RECON?

ps: new 992 reviews are up on Youtube

Ale_72

Regular car mode, as per CTEK instructions.

Thanks! I will update you on the state of the battery tomorrow

Also, I didn't prepare for hibernation properly, so the car has been sitting at 1/3rd fuel for a couple of weeks now. Summer tires are mounted. Is condensation in the gas tank a problem? Temperature in my garage is rather low, temperatures outside are 32 - 40 Fahrenheit / 0 - 5 Celsius.

Would you take the car for a drive to refuel or does this damage the summer tires?

Apologies for asking so many questions, it's my first winter with the car and I forgot to prepare for hibernation due to university exams.

Ale_72

The car will make it to spring. Both with condensation and with summer tires and 0 degrees.

Since the worst of winter is yet to come, it won't hurt to prep the car properly for hibernation. If the road conditions allow (i.e. no salt), pick a relatively warm day (about 40F) and drive it until the car gets to the operating temps (oil temp 190F+) to burn off condensation. Pick up a bottle of fuel stabilizer on your way to the gas station, fill up the tank, add the stabilizer and drive home. Inflate the tires to 50 psi, hook up the CTEK, put a cover on and you are done. Regarding your concern about possibly damaging your summer tires by driving in the cold, the following is what Michelin has to say:

Note: Tires exposed to temperatures of 20 degrees F (-7 degrees C) or lower must be permitted to gradually return to temperatures of at least 40 degrees F (5 degrees C) for at least 24 hours before they are flexed in any manner, such as by adjusting inflation pressures, mounting them on wheels or using them to support, roll or drive a vehicle.

Absolutely! This is what I have always done with my cars I've stored in my garage over the winter. I've used both Porsche Tequipment and CTEK chargers (they make the chargers for Porsche) with good results. I had the MUS 4.3 for my Boxster which worked fine.
