Trickle Charger Question - 986 Forum - The Community for Porsche Boxster & Cayman Owners

I use a CTEK maintainer. It is the same unit that is re-branded by Porsche.
I fount mine on Amazon last year but have seen them locally at Canadian Tire cheaper.

I use a cigarette lighter adapter. Simple and works great.

I broke down and bought the Tequipment maintainer that plugs into the cigarette lighter. I got it from the local Stealership, so I paid too much. But, it's really simple. If the weather is clear I unplug it and go. Back in the garage it takes thirty seconds to plug it back in, and I never open the bonnet.

I finally bought the battery tender jr today. I should have done this a long time ago. While it's the end of January I'm moving the car this weekend (snow permitting) to my mother-in-laws house for 2-3 more months since she's a snow bird... I should have done this in December.

May even break 30* this weekend, Steve. These little Battery Tenders are great for many things; lawn tractors, etc. I'm going to buy a second one because my son's Jeep Liberty only gets driven short miles here and there; I think it could benefit from being plugged in a couple times a week, just to keep the battery fully charged.

Funny thing, my 911, which is stored in a friend's heated building in Wisconsin, is left unplugged all winter. It has an Optima Red Top dry cell which never looses any power when left sitting (car has a battery cutoff switch). As for the Box, I'm on my second OEM Moll battery, but will consider an Optima when the time comes.

I also have a red top in my Pcar, but that was dead this morning... I was in Costa Rica for a month and I guess my car has a constant battery draw - and the insane cold (heat was off in garage) couldn't have helped it much. When I came here to ask about this subject, this thread had already covered all the bases! I think I'll save a few bucks and time and pick up a Sears battery maintainer instead of ordering a Porsche labeled one online.

Thanks once again to the many helpful people here!
