Not sure about a 997 but on my old 987 I disconnected the battery and shut the bonnet without thinking and then couldn’t open it even using the pull out jumper terminal in the fuse box as the circuit was broken.

Suggestion · Original poster

I'm considering disconnecting my 997 battery for the remainder of the winter so it doesn't discharge as quickly (parked on the street, so can't trickle charge) Does anyone know if I disconnect my battery whether I'll still be able to use jumper leads to power the car and get the boot open and access the battery again?

The trick I use to keep the passenger door locked with a dead battery is to just use the physical key to unlock the driver side door.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I'm considering disconnecting my 997 battery for the remainder of the winter so it doesn't discharge as quickly (parked on the street, so can't trickle charge) Does anyone know if I disconnect my battery whether I'll still be able to use jumper leads to power the car and get the boot open and access the battery again? I just want to make sure I'm not making a circuit incomplete and then be unable to access my boot. Thanks!

POST 2Original post

There's a busbar that extends out from the fuse box for the jump leads. I used that to power the car to get the frunk open then jumped it onto the battery.

POST 3Original post

Perhaps get a solar panel trickle charger and sit it on the dashboard. I believe they work behind glass and it would save you so much bother. Just find a 12v outlet that stays live after you have locked and the car has shut down.

POST 4Original post

Trouble is that you can't lock the passenger door with the battery disconnected.

David W. said: Perhaps get a solar panel trickle charger and sit it on the dashboard. I believe they work behind glass and it would save you so much bother. Just find a 12v outlet that stays live after you have locked and the car has shut down. ^This - Harry Metcalfe used one of these to keep his Merc SL600 alive while sat unused for weeks down on the (I think) French south coast. Use the actual cigarette socket, as, while all three sockets in a 997 are live all the time, it's the only one which has full 12v capability. The other two can only provide Phone, Garmin, etc. charging and fuse out above a certain load.

POST 6Original post

A friend's 987 forgot it had heated seats when the battery was disconnected for a short period, they needed to be coded back in by a garage. Suspect much of the ECU and options programming will be the same so just something to watch out for.

POST 7 / ORIGINAL POSTEROriginal post

Thanks all. The trick I use to keep the passenger door locked with a dead battery is to just use the physical key to unlock the driver side door. Or I could lock the doors before disconnecting the battery. I've tried the solar, but doesn't seem to do it in the winter days. So can anyone confirm that putting jumper leads on the fuse box can actually open the frunk even when the battery is disconnected? I just want to make sure there isn't an incomplete circuit if it's disconnected.

POST 10Original post

Not sure about a 997 but on my old 987 I disconnected the battery and shut the bonnet without thinking and then couldn’t open it even using the pull out jumper terminal in the fuse box as the circuit was broken. Searched the internet and established there was a cable hidden behind one of the front wheel arches so I called the AA but they couldn’t find it and gave up but offered to relay me to my local OPC! Luckily I have a mate who is a mechanic and he came to my rescue. So be careful…..

POST 11Original post

After connecting the slave battery to the fuse box and the hinge/striker plate; make sure you use the remote to unlock. I have found that if you use the manual switch it will not open.

This is a source reference. Confirm exact model applicability in the original material.
