5 SIGNS YOUR Bentley
battery is dying
What are Bentley-specific signs of a weak battery?
Bentleys often show battery issues through slow or hesitant starting, multiple warning messages appearing together, and comfort or convenience systems not responding correctly. These vehicles are extremely sensitive to voltage drops.
Can a weak battery affect remote entry or electronics in a Bentley?
Yes. A weak battery can reduce key range and cause infotainment, seat controls, climate systems, or soft-close doors to behave inconsistently, especially after the car has been parked.
Why does my Bentley crank slowly with a weak battery?
Bentleys have very high electrical demand at startup. As the battery ages and loses capacity, it can’t supply enough current, causing voltage to drop and starting performance to suffer.
Are there any Bentley-specific issues when replacing the battery?
Yes. Using the correct battery specification is critical, and stable voltage during replacement is important to avoid fault messages. Incorrect batteries or poor installation can trigger ongoing electrical issues.
What if I only hear clicking when I start my Bentley?
This is often a low-voltage issue rather than a true fault. The warnings may clear once driving, but they usually indicate the battery is weakening and should be tested or replaced soon.

Car Batteries Supplied, Installed & Registered to Your Bentley’s Computer
Auto Hero supplies and installs premium AGM batteries designed for the entire Bentley lineup — including models like the Bentayga, Continental GT, and Flying Spur, with batteries available for all Bentley models.
Bentley systems demand high-capacity batteries for stable power, even with the engine off.
Bentley vehicles have exceptionally high electrical demands, with features such as adaptive air suspension, climate-controlled seating, advanced driver assistance systems, and luxury infotainment suites. The electrical system is engineered to manage heavy loads consistently, which is why Bentley specifies high-capacity AGM batteries with deep-cycle resilience.
Battery access can be complex, often located in the boot or under seating to optimise weight balance and cabin refinement. Our mobile technicians use OEM-compliant tools and protective procedures to complete installation without affecting trim, carpets, or electronic modules.
Pro Tip:
Many Bentleys require both the main and auxiliary batteries to be checked during replacement. Ignoring the auxiliary battery can cause issues with start/stop systems and keyless entry. Auto Hero’s service includes a full charging system check, battery registration, and BMS reset to ensure seamless integration.
All our Bentley batteries include up to a 3-year warranty, and every standard installation comes with a 24-month workmanship guarantee.

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.

BATTERY FAQ’s
What battery suits my Bentley (Continental GT, Flying Spur, Bentayga, Mulsanne, etc.)?
We confirm the exact battery that meets Bentley manufacturer requirements using your model, year, and engine type. Most Bentley vehicles use large AGM batteries to support luxury electronics, high-current demand, and advanced vehicle management systems.
Can Auto Hero install my Bentley battery at home, work, or roadside?
Yes. We offer full mobile service across all Sydney suburbs and handle Bentley vehicles with specialist care to protect sensitive electronics and interior trim.
Does my Bentley need ECU coding or battery registration?
Most modern Bentley models require battery registration or coding to the ECU/BMS after replacement. This ensures correct charging, protects the alternator, and maintains the performance of the vehicle’s electrical and comfort systems.
Can you test the charging system to see if it is OK?
Yes. We can perform a complete charging-system test to confirm whether the alternator or another component has caused your battery to become depleted, for an additional cost.
Do you test the battery before replacing it?
We can perform a full battery and charging-system test to determine whether the battery, alternator, or wiring is the cause of the issue, for an additional cost.
How long does installation take?
Most Bentley battery installs take approximately 15–60 minutes, depending on battery location and whether ECU/BMS registration is required.
What warranty do Auto Hero batteries come with?
All batteries include a minimum 24-month warranty, with many premium AGM options offering up to 3 years for an additional extended-warranty cost.
Can Auto Hero handle complex battery locations?
Yes. Many Bentley models place the battery in the boot, under panels, or within tight compartments. Our technicians are trained to safely access and install batteries in these high-end vehicles.
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 (Afterpay, Zip Pay) are also available for eligible customers.
Do you remove and recycle the old battery?
Yes. We take away and recycle every battery we replace at no extra cost.
