5 SIGNS YOUR Mercedes
battery is dying
What are Mercedes-specific signs of a weak battery?
Mercedes-Benz vehicles often show battery issues through slow starting, multiple warning messages appearing together, or the stop-start system disabling itself. These cars closely monitor battery health, so symptoms can appear early.
Can a weak battery affect remote entry or electronics in a Mercedes?
Yes. A weak battery can reduce key range and cause infotainment delays, screen resets, or intermittent electronic faults, particularly during startup.
Why does my Mercedes crank slowly with a weak battery?
As the battery ages, it can no longer supply enough current to meet the starter motor and electronics demand. Voltage drops under load result in slow or laboured cranking.
Are there any Mercedes-specific issues when replacing the battery?
Many Mercedes-Benz models require battery registration or system resets after replacement. Using the correct battery type and capacity is essential to avoid warning lights or charging issues.
What if I only hear clicking when I start my Mercedes?
This often indicates low battery voltage rather than a component fault. The warnings may clear once driving, but usually mean the battery is nearing the end of its service life.

Mercedes Battery
Replacement Experts
Car Batteries Supplied, Installed & Registered to Your Mercedes-Benz’s Computer
Auto Hero supplies and installs premium AGM, EFB, and calcium-cell batteries for a wide range of Mercedes-Benz vehicles — including top models like the C-Class, E-Class, S-Class, GLC, and GLE, plus earlier favourites such as the CLK, ML-Class, and SLK — with batteries available for all Mercedes-Benz models.
Mercedes-Benz systems demand high-capacity batteries for stable power, even with the engine off.
Modern Mercedes-Benz vehicles feature sophisticated electrical architectures and, in many cases, dual-battery setups — a primary starter battery and a smaller auxiliary battery to power safety, comfort, and infotainment systems. Correct battery specification and coding are essential to prevent electrical faults, malfunction warnings, or premature battery failure.
We supply high-CCA AGM batteries for models with ECO start/stop and regenerative braking, EFB options for select mid-range variants, and calcium-cell batteries for older Benz models without smart charging. For hybrid and EQ electric vehicles, we also fit 12V auxiliary batteries that support high-voltage systems by powering essentials like lighting, locking, and control modules.
Pro Tip:
Many Mercedes-Benz models house their batteries in non-traditional locations — under the rear seat, inside the boot, or beneath the dashboard — requiring specialist tools, safe power-down procedures, and careful trim removal. Skipping these steps can risk ECU faults or interior damage.

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 Mercedes-Benz (A-Class, B-Class, C-Class, E-Class, S-Class, GLA, GLC, GLE, GLS, G-Wagon, AMG models, etc.)?
We confirm the exact main battery — and auxiliary battery if fitted — based on your Mercedes model, year, and engine. Most modern Mercedes vehicles use AGM or EFB batteries to support Start/Stop systems, comfort electronics, air suspension, and high electrical load.
Can Auto Hero install my Mercedes battery at home, work, or roadside?
Yes. Our mobile service covers all Sydney suburbs. We install batteries for all Mercedes cars, SUVs, vans, and AMG performance models.
Does my Mercedes require battery registration, coding, or a BMS reset?
Many Mercedes models require battery registration or BMS/ECU initialisation after replacement to ensure correct charging and electrical-system stability. Some models also require auxiliary battery checks. We confirm this by your exact model and year.
Can you test the charging system to see if it is OK?
Yes. We can test alternator output, voltage regulation, and wiring to identify whether a fault caused the battery to drain — for an additional cost. Models with dual batteries or auxiliary systems may require extra testing.
Do you test the battery before replacing it?
Yes. We can perform a full battery health check and charging-system test to determine whether the issue is the battery, alternator, auxiliary battery, or a wiring/system fault — for an additional cost.
How long does installation take?
Most Mercedes battery replacements take 15–60 minutes depending on location (boot, engine bay, under-seat, or dual-battery tray) and whether BMS coding is required.
What warranty do Auto Hero batteries come with?
All batteries include a minimum 24-month warranty. Many premium AGM or EFB batteries offer up to 3 years with an extended-warranty upgrade.
Can Auto Hero handle complex Mercedes battery locations?
Yes. Many Mercedes models have batteries located in the boot, under seats, behind panels, or use a second auxiliary battery for Start/Stop or SBC braking systems. Our technicians are trained to safely access and replace them.
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.
