Default Do I need Battery Maintainer?

Like to get your thoughts, only driving the car 1-2 times a week, in the winter there will be longer periods without driving it, maybe as long as a month depending on weather and being out of town.

I've been told these batteries don't like to sit and can die on you, the previous owner didn't drive the car much (16k miles since new) and he had several receipts for new batteries.

When it comes to buying a new battery I would recommend looking at the lithium options...i use a voltphreaks model and have not plugged in my car since i got it. expensive but so nice to be able to leave it for extended periods and not worry about it.

i have a CTEK. Does the job well and had a good reputation. A lot of manufacturers that issue battery tenders with their cars use rebranded CTEKs

I've been using a battery tender for 6 years. I like that it maintains the battery instead of a constant charge.

I have the standard Porsche ( Ctek) maintainer; PO also used one too on the same Interstate battery. It lasted 7 years. Just bought an AGM Platinum at Sams Club; hopefully, it'll do what its supposed to for alot longer.

Yes, you need one. I have this one: http://www.ebay.com/itm/NOCO-Genius-...ZW34Mh&vxp=mtr

Ebay seller is a Porsche guy and I've met him a few times at Porsche swap meets, and have purchased other stuff from him - super nice and reliable guy!

Good choice, normal mode is all you need. I do every other week as my mechanic recommends. So far so good with the Interstate 6 yr battery. Great warranty

FYI, the Porsche brand maintainer is produced by CTEK.

Yes, you do. Plus, leave the hood cracked open.

The hood release is electrically controlled.
If the battery dies, you can't open the frunk and jump the car. You'll be going through the problem of opening it by hooking up a battery or charger through the fuse connection in the drivers compartment, which is a pain and doesn't always work.

I would also recommend to remove the tow hook, RIGHT NOW, from the frunk, and put it in the glove compartment. If your car dies, and you can't get the frunk open, and you need a tow, you can't get the tow hook out if it's still in there. The tow truck guys will hook their tow hooks to just about anything under your car and bada bing bada boom, you've got damage.

From experience...
