5 SIGNS YOUR Subaru
battery is dying
What are Subaru-specific signs of a weak battery?
Subaru vehicles often show battery issues through slow starting, warning lights on the dash, or electrical features not working correctly. These symptoms usually appear as the battery begins to lose capacity.
Can a weak battery affect remote entry or electronics in a Subaru?
Yes. A weak battery can reduce smart key range and cause infotainment delays, screen glitches, or intermittent electronic faults, especially during startup.
Why does my Subaru crank slowly with a weak battery?
As the battery ages, it can’t supply enough current to the starter motor. Voltage drops under load result in slow or hesitant cranking.
Are there any Subaru-specific issues when replacing the battery?
Using the correct battery size and cold cranking rating is important, particularly for vehicles with additional electrical systems. An incorrect battery can lead to starting issues or warning lights.
What if I only hear clicking when I start my Subaru?
This usually indicates the battery is nearing the end of its service life. Intermittent starting is a common sign the battery should be tested or replaced soon.

Car Batteries Supplied, Installed & Registered to Your Subaru’s Computer
Auto Hero supplies and installs premium AGM, EFB, and calcium-cell batteries for a wide range of Subaru vehicles — including popular models like the Forester, Outback, XV/Crosstrek, Impreza, WRX, and BRZ — with batteries available for all Subaru models.
Subaru systems demand high-capacity batteries for stable power, even with the engine off.
Subaru’s trademark Symmetrical All-Wheel Drive system and BOXER engines put unique demands on the electrical system. Higher cranking amps are often required to turn over horizontally opposed engines, especially in cold conditions or after long periods of inactivity. Stop/start variants and EyeSight-equipped models have additional power draw from advanced driver assistance systems, adaptive cruise control, and lane-keeping technology — making correct battery selection crucial.
We also service hybrid and mild-hybrid Subaru platforms, supplying EV-safe 12V auxiliary batteries for models such as the Subaru Crosstrek Hybrid. Every installation includes ECU battery registration and BMS recalibration where required, ensuring the alternator and smart charging system optimise for the new battery.
Pro Tip:
Many Subaru models have batteries secured with tightly fitted clamps and crossbars, meaning incorrect tools or techniques can damage nearby hoses or sensors. Our technicians use torque-calibrated tools to ensure a secure fit without over-tightening.
All our Subaru batteries come with up to a 3-year warranty, and every standard install includes a 24-month workmanship guarantee. We provide full mobile service — at your home, workplace, or roadside — so your Subaru is ready for your next adventure without downtime.

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!??

BATTERY FAQ’s
What battery suits my Subaru (Impreza, WRX, Outback, Forester, XV, Liberty, BRZ, Crosstrek, etc.)?
We confirm the exact battery required for your Subaru based on the model, year, engine, and electrical system. Many newer Subaru models use EFB or AGM batteries due to Start/Stop (Auto Stop) systems and high electrical demand, while older models may use standard lead-acid batteries.
Can Auto Hero install my Subaru battery at home, work, or roadside?
Yes. Our mobile service covers all Sydney suburbs. We install 12-volt batteries for all Subaru hatchbacks, sedans, SUVs, performance models, and the BRZ.
Does my Subaru require battery registration, coding, or a BMS reset?
Some Subaru models with Start/Stop or smart charging may require system resets or relearning procedures after battery replacement. Not all models require coding. We confirm based on your exact Subaru model and year.
Can you test the charging system to see if it is OK?
Yes. We test alternator output, voltage regulation, and wiring to determine whether a fault caused the battery to drain — for an additional cost. Subaru models with high electrical loads often benefit from a full diagnostic.
Do you test the battery before replacing it?
Yes. We provide a full battery health check and charging-system test to confirm whether the issue is the battery, alternator, or a wiring/system fault — for an additional cost.
How long does installation take?
Most Subaru battery replacements take 15–60 minutes depending on battery location, access points, and whether any system reset is required.
What warranty do Auto Hero batteries come with?
All batteries include a minimum 24-month warranty. Many premium EFB or AGM options offer up to 3 years with an extended-warranty upgrade.
Can Auto Hero handle complex battery locations in Subaru models?
Yes. Subaru models can have tight engine bays, plastic covers, or trim that must be removed to access the battery. 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.
