i recently got the dreaded battery drain. the only thing i did that i think might be causing it , is i replaced the drivers side interior door handle as the original one broke. could the new one be putting to much pressure on the switch that makes the window open and close when you open the door. the battery is from 2023. i plan on charging and testing the battery. any thoughts on what to do. thanks
That seems thin but looking where you last worked is always a good call. I would isolate the fuse the door window is on, remove it and if the battery stays up, there’s your answer. Also, three years on the battery depending on usage could be on the replacement bubble.
Can you describe the battery issue? Might be something else or maybe it needs to be on a tender. BTW, some of the better battery minders (
CTEK
for ex.) have a mode to restore weak batteries.
charged battery as it went dead over the winter. only thing i did to the car was replace the interior door handle that was floppy. started car and put in garage for 4 days. car would not start.
You need a new battery. They don't like to be "dead" ever... once dead, they are often damaged.

- 2023 seems very new for a battery. My hot take would be to first see if you can have the battery replaced under warranty, and definitely put it on a charger going forward if you're not driving it regularly. For microswitch stuff, I like to use a PIWIS to quickly see if something is actuated or not -- especially if there's a part on the opposite side of the car to compare it to. Anything aftermarket on the car? Finally and unlikely, did the issue start only when you went into the door to correct the door switch? If so, you can remove the switch and test the switch leads on a bench to see if it's stuck. Parasitic battery drains can be a pain but it feels great if/once you solve the issue at hand. Let us know how you get on with all this. Cheers.
Thanks for the tips, turns out battery is shot. Got a free replacement and will be putting in the car today. .I believe that should fix it. Thanks again
I am a big fan of replacing a battery before it gives you trouble. I purchased a
2014 Boxster Base
in 2022. Drove it without issue until last fall. It was definitely starting to crank a little slower, but it always started fine. It was fairly cold when I started it up for it's last journey to its winter sleeping place. It cranked really slow and for the first time I got a check engine indicator, and it was not running optimally. Parked it for the winter, and I put the trickle charger on it. I purchased a new battery and replaced it when I got it out of storage a few weeks back. Cleared the codes and everything is good. I was shocked to find the battery I removed was a
Porsche
branded batter with a date code of 45-13. This battery was made a few weeks before the
Boxster
made its way down the assembly line in November of 2013. I am not sure I understand how a battery can last that long.
It was a Banner with a
Porsche
label.
Historically, any batteries I have replaced have been very close to the time shown on the warrantee.
