Which battery conditioner/charger?

[sgrimshaw]

Need to get a conditioner/charger for a Cayenne Turbo 2019 which has a lithium battery.

Porsche do one, the "Porsche Charge-o-mat Pro" for £160, which I believe is a rebranded CTek unit.

Is there anything better?

[Doofus]

Yes. C-tek. Just get it from Amazon, not Porsche.

Still considering which battery charger/conditioner to get for my 2019 Cayenne which has a lithium battery.

I know the CTEK one is the "same" as the Porsche one, but there's a few others which seem to offer similiar features. So I've narrowed it down to:

CTEK CS-One
OptiMate 2 Duo
Noco Genius 5

Cost is not particularly an issue, but one attraction with both the Noco and OptiMate is they have dual output versions (Noco Genius 10 and OptiMate Duo 2 Dual respectively) which would be a neat solution as we have two cars used infrequently sat on the drive.

Any thoughts from the PH collective?

CTEK lithium 5 would be my choice. Buy an extra hard wire set up so you can fit to positive terminal and point in both cars and switch using the simple connection when required. I think the other two you have suggested come with croc clips.
I run 2 cars off my CTEK. Leaving it on the Porsche most of the time as it seems more power hungry. The other car (Clubsport S) will go weeks without.


This one does both lithium and other batteries: https://www.ctek.com/uk/battery-chargers-12v-24v/c...

And this connector has indicator to show charge level: https://www.ctek.com/uk/battery-chargers-12v-24v/a...

Looks like the CS-One has replaced their other Lithium chargers.

When you say you fit direct to the positive terminal and neg point, is that somewhere under the bonnet?

Be kind ... totally useless with regard to vehicular diy ...

Yes. The CTEK has a connecting cable you leave permanently attached to the car. It has metal rings that go on the bolt that holds the positive terminal on the battery, and the other on the bolt on the earth point next to the battery (or negative terminal in some cars). It has a quick connector the other end that plugs into your CTEK. The one I linked to has charge level lights in the connector so you can see when your battery needs a top up / connecting.
I think it's the best system.

PS it takes 5 mins to fit the cable, and is simple
And about 5 secs to connect the CTEK.
Note: the CTEK often comes with the "covenience" adaptor that you leave on the battery (as well as croc clips for other use) so you should only need to but one extra connector for the second car.

Oops! Seems the battery on a Cayenne is under the seat, so either permanently connect the cable there, or use terminals under the bonnet (there will be some). Perhaps a Cayenne owner can chip in...

Yes, it's under the seat and a total 'mare to get to.

Fortuneatly, the manual expressly tells you to use the under bonnet terminals for charging the battery or jump starting the car

[sgrimshaw]

Confusingly, the manual tells you to use the 12v socket for charging in one breath and in the next says the socket disconnects after 30 mins.

Clear as mud!
