Kev62 Posted December 19, 2019 Report Share Posted December 19, 2019 Hi all I have just purchased a Noco Genius 2 battery charger maintainer for use over the winter the Device works great when I connect to the battery with the croc clips but bit of a faff having to keep opening the bonnet and removing the plastic cover. Does anyone know if it’s safe to connect the charger into the 12v cig socket?? Link to comment Share on other sites More sharing options...
entdgc Posted December 19, 2019 Report Share Posted December 19, 2019 Mine is a 987 and a different charger/maintainer (actually a Lidl one) but I use the 12v cig socket in the centre. Works well. On some models the sockets don't stay live so check first. Link to comment Share on other sites More sharing options...

Have added hard wired connections to the battery and brought it out near windscreen scuttle if the battery were ever to suddenly fail. At least able to get some power to pop the frunk. Your lidl version should be able to use the cig lighter Link to comment Share on other sites More sharing options...
JohnSyn Posted December 20, 2019 Report Share Posted December 20, 2019 Some 981 owners have had problems but I plug my battery charger into the socket in the centre box. The trick is to connect up and then turn the car off. This, for mine, seems to keep this socket live. Link to comment Share on other sites More sharing options...
Carmand Posted December 20, 2019 Report Share Posted December 20, 2019 Best not to connect directly to both sides of an AGM battery in any event - use the earthing point - its explained in the manual. Link to comment Share on other sites More sharing options...
ATM Posted December 23, 2019 Report Share Posted December 23, 2019 I've put my charger with crocodile clips onto the correct mounts under the bonnet and then closed the bonnet. You need to completely remove the big plastic cover obviously. The mains lead for the charger needs to exit so I pinch it at the corner of the bonnet away from the catch. Right at the front corner. Works fine. Link to comment Share on other sites More sharing options...
Kev62 Posted December 24, 2019 Author Report Share Posted December 24, 2019 Does anyone know why you can’t connect the charger direct to the battery terminals? cheers Kev Link to comment Share on other sites More sharing options...
Mushroom3 Posted December 24, 2019 Report Share Posted December 24, 2019 I've said this before but if you have a passenger footwell socket plug it in there. That's what the dealers use - I asked them when I bought mine. Link to comment Share on other sites More sharing options...

Kev62 Posted January 1, 2020 Author Report Share Posted January 1, 2020 Just stumbled across a solution to the front boot light staying on when the hood is open for charging. If you press lock on the key fob when the hood is open it turns the light out. Link to comment Share on other sites More sharing options...

When charging an explosive gas is given off and it is possible when disconnecting the charger to create a spark and ignite it hence you connect the negative to an earth point AWAY from the danger area. There are many mitigating circumstances such as CTEK DO NOT CREATE A SPARK to name but one. Link to comment Share on other sites More sharing options...

But the approved +ve connection point is the battery terminal which can still spark when making the contact. I believe that the correct answer is as @zagamuffin says.

Not on my 98 986, it stays on until the frunk is latched. Porsche has constantly messed about with the design over the years. Link to comment Share on other sites More sharing options...

I believe that the correct answer is as @zagamuffin says. The amount of hydrogen given off while charging is negligible so not really an issue , it’s also not a sealed space so no risk ...

Pretty sure this is why when jumping a car and the battery is discharged you connect to a remote negative point on the battery being charged and disconnect the negative BEFORE the positive. LOL, no risk Link to comment Share on other sites More sharing options...
topradio Posted January 2, 2020 Report Share Posted January 2, 2020 I did know somebody who blew up a battery with a spark igniting the hydrogen produced. It was many years ago before sealed batteries which may have made a difference. When I was a kid we regularly used to split water into hydrogen and oxygen using electrolysis and captured the gasses. We once made a demijohn full of hydrogen and when we lit it, from afar with a spark, it shattered the container. Link to comment Share on other sites More sharing options...

Ahh but define sealed I remember seeing a Sealed alarm standby 12v battery that resembled a football, now there was an imminent explosion in possibly two senses of the word.
