I've left mine a week at a time regularly without problems on startup. (Until we got -30...), so the 2-3 days only makes sense if a) something's draining it, in which case it's doubtful it would even last 3 days, or more likely b) battery's toast. But the dealer is right, a few miles isn't enough to charge. My rule of thumb after a boost is 15 minutes run time to charge (assuming stereo, headlights etc are off).

Michael,
If I recall correctly, it is in the weather stripping on the bottom of the door, near the the center of the door. I can't recall if it was on both doors or just one. Let me run out to the garage and check....... oh wait..... I don't have a 996 any more!![banghead](https://rennlist.com/forums/graemlins/banghead.gif)
I don't think I was dreaming when I saw it.
Let me know when you find it on your car.

Thanks for the tip! Now, to figure out the best way to get the cable to stay in the notch as I shut the door...

WHEW!!! I was starting to wonder if my "grey matter" was failing me!
It's good to know that I am still "tarp as a shack!"

Heat plays a very big role in battery life, too. For every 15°C over 77F, battery life is halved. If you leave a car baking in the Florida sun 12 hours a day, the batteries are going to go faster than a car that's garaged in North Dakota; assuming the battery in ND is not left to discharge over the winter, at least.
You can drain a modern battery down to about 80% a reasonable number of times without noticeable drop in battery life, but taking it lower than that, like to the point where it can't start the car, will ruin a battery in one shot. How long this is depends on the battery and the temperature, but they should be recharged at least once a month, whether via a 12V charger or by driving around long enough for the alternator to charge them; 2 or 3 minutes a month won't do it if the battery has been sitting around a while, it has to be a longer trip.
Overcharging will harm them, too, but most chargers are designed to drop back to a trickle charge once they're done, which is generally pretty safe.

I just started my car after about 2 weeks sitting. It almost didn't turn over! I don't have a trickle charger - is it too late for this battery, or would a trickle charger get it back to usable condition? I did drive it for an hour, and it starts OK now...but I wouldn't want to get stuck in the cold if/when I drive it again.
Also washed the car today. Went great, until the driveway became a sheet of black ice! Blah. Just a little too cold I guess.

Fortunately for me, I haven't had to drive my Honda for 3 days now, so the past 3 days have been good!

You keep this "driving" thing up, and you might make the entire winter w/o a new battery

Mine is in the garage w the engine hanging down and the intake manifold off, one wheel off and the AOS sitting where the airbox normally would be.... Now to get my new one (Monday) and put it all back together......
