5 SIGNS YOUR Porsche
battery is dying
What are the common signs of a weak Porsche battery?
Porsches often show battery issues through warning messages, slow or hesitant starting, or electrical systems behaving unpredictably. These vehicles are sensitive to voltage drops, so symptoms can appear early.
Can a low battery affect my remote key or proximity entry?
Yes. A weak battery can reduce key range and cause infotainment delays, screen resets, or intermittent electronic faults, especially after the car has been parked.
Why does the engine crank slowly with a weak battery?
As the battery ages, it can’t deliver enough current to meet the starter motor and electronics demand. Voltage drops under load result in slow or laboured cranking.
Why do lights and electronics act strangely?
Many Porsche models require the correct battery type and, in some cases, system resets after replacement. Using the wrong battery can trigger warning lights or charging issues.
What does it mean if I only hear clicking when I start?
This often indicates low battery voltage rather than a true fault. The warnings may clear once driving, but usually mean the battery is nearing the end of its service life.

Replacement Experts
Car Batteries Supplied, Installed & Registered to Your Porsche’s Computer
Auto Hero supplies and installs premium AGM, EFB, and calcium-cell batteries for a wide range of Porsche vehicles — including icons like the 911, Cayman, Boxster, Panamera, Macan, Cayenne, and Taycan, plus earlier favourites such as the 944, 928, and classic air-cooled 911s — with batteries available for all Porsche models.
Porsche systems demand high-capacity batteries for stable power, even with the engine off.
“Porsche’s performance engineering comes with complex electrical demands.”
From active aerodynamics and adaptive suspension to multi-zone climate control, stop/start systems, and high-load infotainment, every system depends on a battery with consistent high-current delivery. For electric and hybrid models like the Taycan and Cayenne E-Hybrid, we also fit lithium 12V auxiliary batteries specifically designed for EV safety and seamless integration.
Pro Tip:
Many Porsches locate their batteries in unconventional spots — deep in the front luggage compartment (“frunk”), under the boot floor, or behind interior trim. Access can require careful disassembly, specialist tools, and memory preservation to retain ECU data, seat positions, and window indexing during replacement.

Had a flat tyre and Matt came to the rescue. Quick call out, super friendly and he had it changed in no time. Top bloke and great service, would definitely recommend Auto Hero!
Matt went above and beyond to help navigate a difficult problem. Highly recommend to anyone needing auto service.
I really appreciate Matt’s help! He responded quickly and arrived right on time, even on short notice and in Sydney’s heavy rain. My car wasn’t starting and he helped me with a jump start straight away. Reliable, friendly, and professional. I’d definitely recommend him for any job
The service was prompt and reasonably priced. I highly recommend it!
Matt was such a nice and friendly with us and kept professionalism. We had issue with our car window which Matt explained and fixed it within few minutes. The whole process from start to finish was well explained and executive. I strongly suggest to have your car issues solved out with Matt from Auto Hero. Thank you for the service.
Matt was very helpful and efficient, replace the battery of my car in no time even explain the condition of my car for me in detail so i know what to expect and how can i take care of it better. Highly Recommended, all the best
Matt did a wonderful job repairing my tyre. From the very beginning, he had such a nice approach over the phone, answered quickly, and was very responsive. He arrived exactly at the time he said he would and fixed the tyre perfectly. Great service, reliable and professional. I highly recommend him!
Matt drove all the way out to us in Gledswood Hills and was so quick and efficient. He was beyond kind and great at what he does. Could not recommend more.
Matt was so efficient, so cost effective (a good $200 cheaper than every other quote to fix my car's side mirror), so communicative, and also just such a great guy. Even offered to give us some money back because it took less time than he thought it would. Cannot recommend him enough!
Was stranded on the road, called auto hero and in half an hour they came to check if everything was okay, helped me with my tires and also educated me on wheel alignment. Definitely will recommend them highly!??
Loved it:) The process was simple, easy and fun. Will definitely be using this service again.
Big big big thanks to Matt, I had large metal object in my tyre being a new wanted to ensure I had a professional change and inspect my tyre little did I know how easy and fast Matt was ensuring I was safe and he was on the way excellent job very great price not only did change my tyre but ensured my others were good and safe to drive , 10/10 definitely recommend giving Matt a call

BATTERY FAQ’s
What battery suits my Porsche (911, Cayman, Boxster, Panamera, Macan, Cayenne, Taycan, etc.)?
We confirm the exact battery required for your Porsche based on the model, year, and electrical system. Most Porsche models use high-performance AGM batteries due to Start/Stop systems, high electrical demand, and sensitive ECUs. Porsche EVs like the Taycan use a 12-volt auxiliary battery in addition to the high-voltage pack.
Can Auto Hero install my Porsche battery at home, work, or roadside?
Yes. Our mobile service covers all Sydney suburbs. We install 12-volt batteries for all Porsche sports cars, SUVs, and EVs, including models with tight access or battery compartments under trims.
Does my Porsche require battery registration, coding, or a BMS reset?
Many Porsche models require battery registration or a BMS/ECU initialisation so the vehicle correctly manages charging. This applies to Panamera, Cayenne, Macan, and most Porsche models with Start/Stop or intelligent charging. We confirm based on your exact model.
Can you test the charging system to see if it is OK?
Yes. We can test alternator output, voltage stability, and electrical load to confirm whether a fault caused the battery to drain — for an additional cost. For Taycan and hybrid models, we test the DC-DC converter instead of an alternator.
Do you test the battery before replacing it?
Yes. We perform a 12-volt battery health check and charging-system test to determine if the issue is the battery, alternator, voltage regulator, DC-DC converter, or wiring — for an additional cost.
How long does installation take?
Most Porsche battery installations take 15–60 minutes depending on model, battery location (front trunk, rear compartment, or under trims), and whether a BMS/ECU reset is required.
What warranty do Auto Hero batteries come with?
All batteries include a minimum 24-month warranty. High-performance AGM options may offer up to 3 years with an extended-warranty upgrade.
Can Auto Hero handle complex battery locations in Porsche models?
Yes. Many Porsches have batteries in the front trunk, hidden compartments, or behind body panels. Our technicians are trained to safely access and replace Porsche batteries without damaging trims or electronics.
What payment methods do you accept?
We accept EFTPOS, debit and credit cards, secure online payments, and tap-and-go. Buy Now Pay Later options such as Afterpay and Zip Pay are also available for eligible customers.
Do you remove and recycle the old battery?
Yes. We remove and recycle every battery we replace at no extra cost.
