I bought a set of winter wheels and tires for my 991 Cab, but now that snow has hit the ground I am realizing that I will likely use the 911 sparingly this winter. I work out of the house, and don't put a lot of miles on a car anyway. I can use my wife's RX 330 when she isn't using it, so I could easily have my car sit every other day or perhaps even two days out of three in the winter.

So I think it makes sense to hook it up to a charger, just to keep the battery fresh when the temperatures here in the Chicago suburbs are low, as they are now. Does this seem like a good strategy? Also, I believe the choice here seems to be the CTek 3300. I would also get the cigarette lighter attachment for ease of plugging/unplugging. Amazon has it for $56 plus another $10 for the attachment. Is that the best place to get it? Any other thoughts appreciated, but this seems like a no brainer...

OK.

Or: BTJr. Attach the pigtails to the battery and poke the connector through one of the slots. The tender is small enought to keep in a small bag in the trunk when not in use.
Simple safe and effective. I have 8 Smart Chargers of the same brand, different models including multi-charging units.

I actually use the porsche one (ctek) that plugs into the outlet in the passenger footwell. Easy, works perfectly.

The door rubber seal allows the door to be closed safely over the wire. Just don't drive off without removing it!

Isn't that the same one I am considering, minus the Porsche logo?

i have heard that the battery needs to be disconnected from the car when charging. is this true

MerlinsGarage

Not with the tender.

I bought the CTEK when I took delivery of my car as I go several days per week between drives. Lately it has been 6-7 days between drives and when I hook the car up to the charger, I have plenty of juice left in the battery. Not sure it's necessary. It's been cold here (high 20s) at night but I'm not really seeing the need for the charger. Probably wouldn't buy it knowing what I know now. And I sure don't miss those Chicago winters that you have!

I have the Porsche Branded Ctek on both Porsche's. The dealer actually gave me one at delivery time for the new 991. Both work great.

I have a cteck without the outlet attachment. Can I still use this and just hook it up to the
terminals?

I'm going to get one of the Porsche battery tenders - but at the moment, my 991 has been sitting for a month in the garage undriven due to me being out traveling for the past month. Let's see if it'll start up when I get home this weekend. Uggh I hope it will anyway.

If I ain't driving it, it's plugged in. Winter. Summer. Hot. Cold. One day. 100 days. Does not matter. Too simple not to do. These cars eat tires and batteries.

I use them on every 12v Battery that I own. Let me see, i have 9 of them and haven't bought a battery in years. Including trolling motor batts..

If a "Battery Tender" breaks, i send it to FLA (plant) and within 2 weeks i have a new one. I doesn't matter that they are out warranty or not.

Thx, I'm going to order the 3300 and cig adaptor from Amazon tonight unless someone else has a better deal and speaks up pretty darn soon. :-)

Does power stay on to the footwell socket in a 991? I am pretty sure it doesn't in a 997 and you need the socket to stay "active" after the ignition is turned off to charge battery through the socket.
