Trickle charger is your best insurance. I ran a jumper off the battery to the little trim access cover. The trim piece needs to be cutout slightly to allow routing the connector. Hides away when not in use.
That is a nice little setup. But just trying to figure out how to then route an electric cord to where my car sits without having people trip over it since it would have to cross a walkway.

Park it in my driveway and I'll keep it charged for you.
Haha I'm sure! I should drive it more often but as it is I barely drive anyway. I go to the gym and I drop my kid off at school. That's it, so at this rate it'll take decades for my Cayman to hit the same mileage milestone that my 996 has achieved.

Start by pulling the relay box cover and feeling around for a warm relay. Temp gun may make it easier to locate what is pulling a draw. It may also be as simple as one of your illumination lights are staying on due to being switched on or a pin is broken and not cutting the power, such as the frunk light.
I always thought this was just a common issue with the 996 series? I remember going to test drive a turbo once and seeing the dealer have a tender on it because he said it would kill the battery after a couple of weeks sitting. I just thought that was normal behavior. But I guess looking for parasitic draw would be a good idea if this isn't the way it's supposed to be.

Terminology is also important: You want a Battery Minder or Battery Tender not a “trickle charger.” The latter term is often used expansively to cover both types of devices. Also, if you have an AGM battery you will want a Minder/Tender specifically for AGM batteries.
This, if you get tired of looking for the drain.
And, yes, it is reasonable(*) to assume that you will have less parasitic draw with the alarm off.
Aftermarket stereo or other add-on gizmos? Notorious for excessive current draw.
In terms of reasonable, this is true for the 9 generations. Those also have a “transport mode” that can be switched on with PIWIS (perhaps iCarSoft and Durametric too) that drastically reduces current draw. 996? Dunno.
Yeah I was thinking battery tender but instead called it a trickle charger.
I don't have any electronic aftermarket devices on the car. The only thing that should be drawing power now is the alarm.
I'll drive it and then leave it unlocked to see if it makes a difference. I'll look at my Durametric settings and see if there is any type of "sleep" mode I can put it in.
