Hi everyone, I have a 2018 718 Boxster S, my battery is in healthy condition. The car will sit stationary for 3 months, living in a condo, battery tendering is not an option, so I decided to take out the battery and tender it at my unit. My question to you all is :

Do I need to do anything upon re-install the battery? Your inputs are greatly appreciated.

James,

Since I assume that you plan on locking the car while it is laid up, make plans and practice how to open the front hood when there is no battery to unlatch it.

Ah, thanks for the reminder, arne.

On further thought, I seem to recall reading that the emergency jumper connection in the left fuse box doesn't work if there is no battery installed. Apparently a battery (even if dead) is required to complete the circuit. If so (and I don't not know if this is true or not), that would mean that your only option will be to be prepared to jack up the LF corner, remove the LF wheel and inner fender liner so you can access the emergency release cable. In this case, make sure your wheel lock key is not also locked in the front trunk.

Given all this, if it were me, I'd just leave the battery in place and be prepared to replace it if necessary when the car is recommissioned. It just doesn't seem worth the hassle.

My plan is to leave the frunk open and use car cover during this period. I believe it would work.

As long as no one 'accidentally' or 'trying to help' pushes the lid closed, you are probably OK.

After reinstalling, you will probably have to re-index the power windows, perhaps some other 're-learning' things.

Is it possible to 'close' the latch in a 718 while the frunk is open so no friendly person or yourself could accidentally shut the frunk? Also, while charging in your unit, is it in a well ventilated area? As I believe the battery can give off flammable vapors while charging? If in a confined space that could be problematic.

Most of my vehicles are on battery tenders but, due to last minute space limitations, I stored my CGTS at a friend's storage facility for almost 5 months this past winter.
All that was needed was:

1. Fully charge the battery before storage. Allow a full evening on a good battery charger the day before storage. The car's charging system typically only gives you something like a 90%-95% charge.
2. Disconnect the negative terminal (I isolate it by wrapping the negative end)
3. Place a piece of heavy cloth on the chassis portion of the frunk latch. This way it can't be accidentally closed.
4. The restart should be fine but as a precaution, when you go to restart the car, have a working jump starter with you. If you can, park the car so that it can be jump-started with cables if necessary.
5. After getting the car out of storage, put it on a charger for the first evening to get your battery back to a good state of charge. Your alternator will thank you. 😊

It's interesting that porsches are cars that are very often not driven, and porsche has done exactly nothing to accommodate this very common usage(or lack thereof) in their modern cars

I have a T3 westfalia in europe. This vehicle will not have been driven or battery tendered for 10 months. I don't expect any difficulties whatsoever. All I do is disconnect the battery. The last battery only died because of covid, and I couldn't get there

All that porsche would need to provide is some persistent computer storage, and access to the battery location, ie, cable. How much would this cost? $20, but profit comes before your convenience

We may never recover from the death and destruction wrought by that nasty virus.

Just disconnect the battery.
My FIL does this for 6 months at a time with no issues. He is here during the winter and in MN during the summer.
Don't make it harder than it needs to be.
