Lithium Ion Battery Charger - any recommendations

No problem Clive, we all have one of those ??
One comment you did make that sort of backed up my experience was to check after half an hour to see if all lights were on and if only a green one was showing to start again?? If one followed your instructions why do you think it may not work?

I think I may have messed up the sequence once in the early days with the Macan. So for first timers, it's well worth checking to confirm all's well. [:)]

As I await delivery of my 992 Carrera, I have enjoyed reading so many topics in this forum. However, I was quite alarmed when I read this discussion on Lithium batteries. I am a great advocate of C Tek chargers and I have recently invested in an MXS 7.0. Imagine my concern when I read that this is not suitable for use with Lithium. I then spoke to my Porsche dealer AND to Porsche Reading (to be sure). The 992 Carrera does NOT come fitted with a lithium battery, so I just wonder what damage may have been caused by wrong charger/battery combinations.
I may be wrong but I think only latest GT cars have lithium but even then I would still check.
 
I used a Noco Genius 5 on mine. It will do Lithium, AGM, lead batteries both 12 volt and 6 volt for motorcycles. They work well and kept my TTS topped up through winter lockdown.
 
I use the CTEK charger and cigarette/ accessory socket and works fine. I would just say apart from the advice above without teaching people to suck egg!:
1. Make sure the cigarette/accessory socket is the correct one for the 992 (they are not all the same). The manual shows you which type you can use and my CTEK came with a adapter. If you use the wrong one you may get no connection or a bad connection and the socket may turn itself off.

2. Double check which type of battery you have - they all seem to have Lithium battery sticker on the battery carrier/holder (means you can fit one) but your need to look at the sticker on the battery itself - Mine is an AGM. (My PEC told me they have had a few owners who are adamant they have a Lithium battery when it isn't)

Hi Clive,
My experience with any internal socket (I have a Macan Turbo and a 992 Turbo S) is that all the sockets seem to shut down after a variable length of time whether you're extracting or inputting power and thus create an unstable charging situation. The only reliable method I have found is a direct contact with the battery on the 992 and direct contact to the charging points under the bonnet on the Macan. I wish it were possible to use the 12v sockets in the cars but several attempts have failed to work. On the 992 I have fitted a short permanently screw fitted trailing lead to the battery terminals with a connectable socket to an extension lead which can be fed out through the gap between the windscreen and the wing panel. I chose to buy an OPTIMATE AMPMATIC for Lithium battery for the 992 and OPTIMATE AMPMATIC for the Lead acid gel battery fitted to the Macan. Both chargers are excellent and can be left connected for months. I had the charger on the 992 connected for six months during the winter which kept the battery perfectly fully charged.
One of the benefits of the OPTIMATE charger is that it has the potential to restore a previously thought dead un chargeable battery using an automatic feature within the charger.
Just hope this helps .

I hesitate to pursue the battery charge
set up further but….
I want to connect the battery using the
connector which attaches to the battery
to a lead that can be permanently left
in the luggage area.There are several neat installations on u tube
I assume Porsche don’t show this connection in the manual for safety reasons.However my knowledge is very limited (The Bolton OPC info helpful)
and I wonder if using the chassis’s earthing point is better practice?

 
I am sure that you have noticed this, but on many 992’s the ‘strap’ on the battery may state ‘Li-ion’ but the battery still may be a Lead Acid one with the AGM sticker on.
