Porsche battery maintainer question:
I have purchased a Porsche Battery maintainer from the dealer (Porsche part # 955 044 900 54) I intend to use it on a 2015 Cayman S which is infrequently driven.
My car does not have a cigarette lighter but the plug is labeled "cigarette plug" in the directions and also on the plug. Can this plug be inserted into one of the 12V power sockets or do I need an adaptor? I am hesitant to hook this thing up until I know it is compatible with the 12V socket in the car. ( Visions of smoke and sparks are in my imagination...)
For those on this forum that do use a battery maintainer, do you just keep it hooked up at all times ( except when driving of course...) to keep it on a constant charge? I am new to this and appreciate your input.
Thanks in advance, Pat D

I'm using the Porsche charger on my 2014 Cayman S in the center console plug at the rear of the area. No problems. I run the cord towards the shifter, close the lid, run the cord across the passenger seat and out the door right in the center if the door opening/jam, and close the door. Arm the car locking it, and plug it in. Been overnight and for weeks like thus; no problems.

I don't know which power outlet to use in the 981s.
Maybe your owner's manual could tell? If not, perhaps the dealer.
A true Maintainer is meant to be used 24/7 indefinitely. It has circuitry that allows it to detect the voltage level of the battery, and it charges the battery when needed, but stops charging when the battery is "full" to prevent overcharging.
However, it is a good idea to check the water level in any battery that is more than a year or two old. This includes maintenance free batteries. The water level can decline over time due to overcharging (sometimes by a car's own charging system) and dry ambient conditions. A few years ago I found my 4 year old battery to be close to 1" low in most of the cells.
For my maintainers I use the cigarette lighter outlets in my 987 and 996.
