New battery

[SAC1]

new battery in 3 years, sounds like a issue as should be good for 6/7 at least

3 years is about right unfortunately. You'll have done well to get 6/7 without looking after the battery (conditioning)

This is insane! Why would a battery need replacing after 36 months??
I have NEVER had to replace a battery on any car I have owned in the last 30 years! Why do we accept that somehow this is normal just because it’s Porsche.

I agree Jon.

Never needed to replace a battery and never needed to use a battery charger / conditioner. Our cars are not garaged either.

Even during the pandemic lock-down periods when our cars were used just once a week and for short journeys. My Macan SD didn't turn a wheel for 5 weeks when I decided to put on SWORN pending my new GTS. It started first time on collection.

Calm down, calm down. Who said anything about it being just Porsche?

I've known batteries last almost 10 years, I changed my step dad's on his Honda Civic last year, that was almost 10 years old, my conditioner couldn't do anything with it.

Fully Agree. Had over 80k Miles 6 yrs on a couple of BMW Diesels without needing new batteries and plenty of cars I ran for 5 years did not need them. Car batteries at 36 months make me wonder to how often Porsche want to change the TPMS sensors which should also be good for about 7 years.

Well didn’t you say “3 years is about right”?
Feels like you are implying about right for Porsche?
Either way, it isn’t. Most if not all modern cars would see battery life of at least seven years and many longer.

The battery on my DS, is coming up to 6 years old now, and was advised by battery specialist (not OPC), to give it aquick shot or two with a Ctec. Running like new again.
I've replaced the battery on my 968 twice now, after nearly 30 years, not surprised. And thats with conditioner use, which is always on, through low usage.
Trying a Ctec first may save some money.

Buy battery from good source.
Fit battery
Take to a garage with standard vehicle diagnostics (they all have them) and pay £30 to plug in and reset any standing codes. If worried, use a Porsche specialist type. Batteries are not coded, they just throw alarms and limits in the ECU if they're low on capacity, and sometimes these need a reset so everything works, and the alternator circuit knows how to charge the new boy.
Alternatively, give garage battery to fit if beyond your skillset.
No reason an OPC should ever touch your battery unless it's a warranty issue in the usual timescales. Fitting your own does not invalidate your vehicle warranty

I’m afraid this is incorrect. If you are within the Porsche warranty, original or extended, an aftermarket battery WILL invalidate your warranty. I had exactly this and had to replace a brand new after market battery with a Porsche branded battery that can only be bought from Porsche (made by Moll I believe). I was quoted £610 and negotiated down to £490 in the end.
Also, the battery does need coding to tell the car it’s a new battery, otherwise it will think it’s an old battery and over charge it. To complete the coding the program asks for the battery serial number, and you guessed it, it will only accept a Porsche OEM number.
So, your hands are tied if you have warranty or if you want the battery coded correctly

or if you intend to buy/extend a Porsche warranty, presumably!

The stop start doesn’t extend life it works them hard .The additional ECU s crammed in just guzzle juice .Every option you merrily spec likely has a ECU running it eg the rev cam .Comfort pack etc etc .

Ferrari just change them out @ 36 months .No iff no buts . But under £200 and they already have it hooked up the diagnostic thingy so no added Labour as they check and clear codes anyhow .Just save owner grief “ my dash lights “ keep coming on etc etc .
Had a Cayenne that started to minic xmas tree lights on the dash .I did the batt my self as explained above and hooked up my coder cleared the codes .Used OEM Bosch of course from Halfords .

Indeed daft ad it sounds try Halfords they do a fitting + necessary coding service something like £20 .Yes Porsche is just like any VAG car batt wise , nothing special.
You guys for want of a better expression “ numpties” at wrenching are being taken for ride by OPC s .

Any fool with the right coding gadget for VAG vehicles and the RIGHT batt as you say can do this .
Of course fit the correct part to maintain the warranty .Why would you want to invalidate it - huh !

Well this ‘numpty’ has VCDS for the coding, but as explained it asks for a Porsche battery serial number. You cannot complete the coding without that. So you have to buy a Porsche battery from an OPC.

Funny when I asked for advise no-one helped, just slated me for buying a car from Cazoo.

So, I ask, have any of you doubters actually done this yourselves with a Bosch, non Porsche battery. If you have them fair enough, but my actual experience tells me different, which does not make me a numpty.

Thanks
