How to charge battery without removing?
Ok...with the winter almost over in Boston its time to take out my 996 c2. However, the battery is very weak it barely starts. So i went and bought a battery charger but totally clueless how to connect it (i do not know where the battery is located!!).
1) can i recharge it without diconnecting the battery? if so, do i just connect + to + and - to - OR is there is specific way to do it?
2) if i have to remove the battery, can i just disconnect it and reconnect it? OR will i need any recalibration either for the engine management system or the stereo?
As you can tell i am totally clueless...please advise
cheers,
M
PS: where is the battery located?? front or back?

No, it will be on an index-sized card. If you don't have it, you'll have to go to the dealer so they can verify your vin.

you'll also have to reprogram the power windows / roof for one-touch operation.
Get in car and close doors, turn key to "on" position.
Press "Down" on window until all the way down then hold for 3 seconds. Press "Up" until all the way up and hold for three seconds. Repeat for other window and roof.
Test one-touch up and down. If it does not take just do it again.
You thought about buying a battery tender from Detailers Domain or Porsche? Might be handy..

Thanks!!
The manual of the battery charger also states that one could charge it by connecting positive to positive terminal and negative to something heavy, unpainted like... chassis/body (but not the negative terminal) .....does that make sense?? (thus avoiding to disconnect the battery)

Get a battery maintainer/charger. It just plugs into the cig lighter and you don't have to worry about disconnecting anything or reprogramming your radio or windows.

Those work well and so does a Battery Tender. Just connect pos to pos - Red/red and Black/black neg, let it charge. Lights will go from Red (charging)to green (fully Charged). No need to disconnect Battery and you can visually check water levels in the battery while connected. If there is a charge left there will be no need to reprogram anything. I use these on my other vehicles and pwc batteries for winter storing. It works like a champ

never thought my car had one-touch window or sunroof operation. so I tried the re-programming trick and it worked. then, just a little bit later, it didn't work. so I re-programmed it again, and it doesn't work. tried several times. thoughts?

Just to let everyone know. When the batt dies the security is enabled. U have to disable with remote button but mine wasnt working. The trunk is locked and coont be accessed easily. You have to literally break in by moving the locking device from the lever with a knife or think screwdriver. Hard to explain but found it on goooooogle

this is damn interesting. I just replaced the battery, but it had enough juice to open the front and back. the book says you can open the door with the remote and then use a portable battery thing to open the trunk and rear by connecting to a pos post at the fuse box and neg at the door hinge. but if the remote isnt working, wouldn't the key open the door to access the fuse box? and if there's no juice then the alarm wouldn't go off? I didnt what you did could be done.

Well what I read is once the battery is dead then I assume it releases a little metal slide which moves into place and stops u from opening front trunk. I was still able to open the back and jumped it and charged it that way but even when the car was on and running I couldnt open the front. But thats because I wasnt able to activate and deactivate the alarm being my remote doesnt work....
