I only drive my car on the weekends and the Exide in my GT4 has lasted nearly 4 years since I bought the car from a Porsche Dealership in late 2017 with 1200 miles on it.
I had the dealer run my VIN and apparently the previous owner never had this Exide replaced, so it is in fact the OEM battery since the car was brand new.
In fact, it's probably right at 5 years given my "build" date.
After doing some due-diligence, I have networked my way over to VW and am gonna get the same Exide battery that is currently in my GT4.
The Exide 5L0-915-105-D has been replaced by Part #: 000-915-105-DE
It costs $155 and I get another 10% off with my AAA card.
The only downer is Porsche needs to re-initialize the new battery and they charge $230 for doing less than 2 minutes of work,
inputting the battery's manufacturer and model number into their computer.
Hope this helps people coming up on a new battery!
Is 000-915-105-DE an AGM battery? This is supposed to be the updated version of the original battery that came with the GT4 and I've read other posts saying the GT4 came with an AGM battery, but the battery is filled with liquid that sloshes around so I don't think it's an AGM battery. I'm trying to figure out what battery type of register/code to the car.
My battery was dead on Friday even though it was using the tender. Replaced with an autozone Platunum h5 AGM. Gotta love how the frunk can’t open w/o power…

Replaced my battery with the H8 and used a battery tender (CTEK) during the transfer. The only thing I noticed after is that my one-touch operation for my window and top no longer function. I have to continuously hold the buttons down. I guess I'll have ot have the thing coded by the dealer! I didn't lose any other "settings' that I'm aware of.
My BMW (M3) had to be coded whenever I changed that battery. A/C compressor didn't turn on, 3rd brake light didn't work and something else didn't work until I had it coded by the dealer.

Stupid technology.
You'll still "need" to code the new battery. You can find OBD scanners that will allow you to do this yourself which are less expensive than the $230 the other guy above had to pay the dealer.
Here's the full procedure after changing a battery:
Information
Control unit memories
Values and faults stored in the control units can be deleted if the battery is disconnected or completely
discharged.
If possible, all fault memories should be checked and, if necessary, printed out before the battery is
disconnected . Information
Supply voltage fault entry
The entry "supply voltage" may be stored in various control units if the battery has been completely
discharged.
Delete the "supply voltage" entry from the control units in question . Information
Ready status
In some countries (presently the U.S.A. and Canada), after disconnecting the battery, it is necessary to
reach the Ready status by a test drive and/or by using the Porsche System Tester DME control module
menu). If in doubt about this, contact the relevant importer. Information
2470 DME control module
With all DME systems, the engine must run for several minutes before the engine control module can
relearn the idle speed and mixture adaptation values!
After disconnection of the power supply, the idle speed might change or fluctuate briefly until the throttle
valve adjusting unit has been readapted.
The mixture adaptation is also lost.
After the battery is connected:
With the DME, it is necessary to carry out a learning and adaptation routine as described below:
Switch ignition on for 30 seconds without starting the engine .
Do not actuate accelerator pedal .
This completes the adaptation of the throttle valve adjusting unit. Information
Tyre pressure monitoring system
When the battery is disconnected and connected, the tire pressure is first displayed as " - - - ".
Once the battery has been disconnected and work is complete, the vehicle must be driven for a
short distance .
The actual pressures will then be displayed again. Information
4560 Steering angle sensor
The steering angle sensor must be re-initialized when the battery is disconnected and connected.
Turn wheels to straight-ahead position .
Switch ignition off and then on again twice .
Start engine .
From the straight-ahead position, turn steering wheel approx. 20° to the right, past the
straight-ahead position .
Drive the vehicle straight ahead for at least one second at a speed above 4 km/h (2.5 mph) .
The steering angle sensor segment is recognized again in this process.
Once the sensor has been successfully initialized, the fault code that is stored in the fault memory is
documented using the fault deletion counter.
The fault memory erases itself automatically.
The PSM indicator light in the instrument cluster goes out. Information
6452 Power windows
The limit positions of the power windows are deleted from the control unit when the battery is
disconnected and connected.
Perform the following procedure for all power windows:
Pull rocker switch and fully close window once .
Pull rocker switch once more .
The upper end position of the window is stored.
Press rocker switch and fully open window once .
Press rocker switch once more .
The lower end position of the window is stored. Information
4815 Electrical steering column adjustment (ELVS)
The electrical steering column adjustment end positions (ELVS) are deleted when the battery is
disconnected and connected.
The following buttons must be pressed in sequence in order to reinitializes electrical steering column
adjustment.
Press the extend button three times (extend towards the driver).
Press the retract button once .
Press the extend button once (towards the driver) .
Press the up button once .
Press the down button once .
Once the buttons have been pressed correctly, the steering column automatically moves all axles and
stops at the center position (only works when the vehicle is stationary).

No, this is not an AGM Battery.
And my indy mechanic charged me $142 to code it.

Youre mistaken.
I never went to the dealer to code my battery.

A little help. I replaced my original battery just now after being on a battery tender for the past 3-4 years. The battery was completely dead. I replaced it with the new VW battery:
000-915-105-DE
Now my PCM module fails to turn on. Everything else seems to work just fine. I checked the 25amp fuse (not blown) and replaced it just in case. Any suggestions on what I can do?
