Is there any special way to keep the battery charged in the winter? Can I use any type of trickle charger? I have an extra Battery Tender for my Harley and was wondering if it will damage the battery to use it on my TT?

 

H-D Battery Tender will work fine - I've used one for 3 years.

 

AGM and gel batteries require a different charging technique. Suggest you read this tutorial:

the ctek 3300 is suitable - I've got it on my 997tt right now. Same as the Porsche one without the Porsche label and much cheaper!

 

I thought the OEM batts were wet cell. The H-D battery tender is just a re-branded Deltan.

 

The Ctek 3300 is good *IF* you use a typical wet cell lead/acid battery. But if you use an AGM type battery, such as Optima, you'll need a different charger. Spend a few more bux and get the Ctek 7002 because it supports wet cell and AGM type batteries.

 

He may have changed out the battery to Optima or Braille, etc.

That's why I suggested he read the tutorial.

 

i bought the OEM one that plugs into the cig lighter, works great and is easy

 

Me2 i think is the best option

 

The OEM one is a rebadged CTEK 3300 (it's on another 6speed thread).

The newer Deltran Battery Tender Plus will do AGM and GEL. OP should check to see if his H-D charger is the newer version. If it's a recent buy probably yes since H-D batteries are AGM.

 

I have been using this little guy for the last year:

I still drive the car 3-4 times a week regardless.
Any thoughts about this particular product?

Reading this thread scared me though. Wow scary to think that could happen.

From one of the sponsors here. I have it connected to my wife's Turbo S now. I have the Ctec 3300 on my Turbo but like the Save-A-Battery unit on my wife's car better.

 

I use battery tenders on my truck and two motorcycles. They seem to work fine. Keep your receipt because they have a ten year warranty. I use the throttle to charge my Turbo.
