Porsche dual-mode battery charger question?
Porsche dual-mode battery charger question?
Looking for some feedback on this charger please? Anyone that has one - do you recommend it? It just plugs into the cigarette lighter or in my case the power outlet in the glove box and trickle charges the car - correct?
I'll be out of the country for a month soon so my car will be sitting in my cold Wisconsin garage and I don't want to return to a flat battery.

its a good idea. works just as described on my 997 3RS.... on my car, i can store it for a max of about 4 weeks before the battery goes flat. so if youre storing for bout a month, a battery maintainer is a good idea.
if you dont want to spend extra $$$ for the "porsche" model, just look up the ctek charger... it looks something like this but is a lot cheaper than the "porsche" one, which is basically a re-branded ctek charger.

I've left my previous P cars on it for a few months at a time with no issues. Def worth getting.
You sure would want to get one. I use Battery Tender and it works great. You will have to order the cigarette adapter separately though, otherwise battery hookup.

I use a battery tender and hook it up at the battery under the hood. I like it better because I don't have to leave a window cracked. Just personal preference. Same result.

In your case, don't you have to leave the hood up or open a crack? Or do you close the hood on the wire?
There are many times I don't get to drive for a week at a time and I used to have worry about battery charge with my 997.1 but it turned out the alternator voltage was set on the low side. When I got the 997.2 it charged at a higher voltage and I never had any problem. The 991 also charges at a higher voltage and to date I haven't had to use a trickle charger.

Again, if you haven't had any problems, then I guess you are OK.

If you haven't had any problems with that, then I guess there are no issues. But I think that circuit has a lower amp rating fuse in it than the cigarette lighter, so you could blow the fuse using the circuit you describe, IF the battery tender puts out too many amps. I think Porsche recommends the cigarette lighter be used. I know they do if you are using the portable air pump to fill up a leaking tire. If you use the one under the glove box for that, you will blow the fuse.

There is a power outlet in the between-the seats compartment- will check the owners manual to see what it says. Thanks or the tip.
+1 for the cteck linked above on amazon. Same as porsche one without porsche written on it. Make sure you get the extra cigarette plug adapter for another 10 bucks as the default 53.00 one doesn't come with that.
Used it all winter and it's done perfect. Car starts perfectly everytime.

I don't have the smoking pkg so I don't have a cigarette lighter outlet. Is it best to use the power outlet in the glove box or in the center console (between seats)? Any difference between the two?
Probably an even more important consideration is to make sure that whatever outlet you are using to charge the car with is "hot" when the ignition is off. I am pretty sure that if you don't use a "hot" circuit to charge with, you won't be charging the battery. I think that is why Porsche recommends using the cigarette lighter to charge because it is "hot" with ignition off. That is on a 997, not sure about 991.
One poster above stated that he had been using the outlet under the glove box for charging and had no issue, so it might not be a problem. I just haven't checked out the details because I don't have the battery tender.
