Everything You Need To Know From Battery Health To Replacement
At Volks Autos, we are an independent specialist garage focused on German vehicles, dedicated to helping you maintain your car’s performance. Your car battery is crucial for powering the ignition system, vehicle computer, lights, radio and more. Since all car batteries will eventually fail, often without warning, it is essential to monitor the condition of your battery regularly. In this guide, we will cover everything you need to know about battery health and replacement to keep your vehicle running smoothly.
Battery Lifespan
In ideal conditions, a car battery should last between three to five years, but its lifespan depends on factors such as vehicle type, electronic demands, driving habits, and weather conditions.
Causes Of Battery Strain
While battery age is a common cause of failure, factors like long periods of inactivity, short journeys, using electronics while the engine is off, and faults within the car can also strain the battery and lead to a dead battery.
Maintaining Your Battery
To maintain your battery’s charge, always turn off your headlights and interior lights after driving. Disconnect any GPS, phone chargers, or other electrical accessories, as they draw power directly from the battery.
How Do I Know If My Vehicle Needs A New Battery?
Apart from a failed battery test, look out for these warning signs:
- Difficulty when starting your vehicle.
- Engine cranking (turning over) more than usual.
- Battery / Alternator warning symbol displayed on your dashboard.
- Your lights are dim or you are experiencing electrical issues.
- Your car battery is cracked, swollen or leaking.
- Is your car cranking over?
Is Your Car Cranking Over?
Many components and scenarios can cause a non-start issue. If your engine cranks (turns over) but doesn’t fire, it may indicate a component failure, such as a faulty injector or spark plugs. On the other hand, if the engine doesn’t crank at all, it suggests a battery or starter motor issue.
If your battery is in good health and the starter motor has a good supply from the battery, it would indicate a starter motor issue. If your alternator has failed, your battery will be unable to recharge when the engine is on, causing the battery to run low and then not be able to turn the starter motor to turn over the engine.
What Is The Difference Between A Start/Stop And Regular Battery?
A start/stop battery provides a larger current to the starter motor, enabling the car to restart quickly when you engage the pedal. Unlike regular batteries, it automatically shuts off the engine when the car stops, conserving fuel and reducing emissions. While start/stop batteries may look similar to regular batteries, their functions are different. Regular batteries are designed solely for starting the car, whereas start/stop batteries continuously discharge and recharge.
With the increased demand from modern vehicles’ electrical systems, it’s essential to ensure the correct battery is fitted for optimal performance.
How Long Does An Electric Car Battery Last?
Electric car batteries are slightly different from fuel car batteries. Electric cars rely on their batteries to get you from A to B, whereas fuel cars depend on petrol or diesel. An electric car battery is made of lithium-ion, which means it can deteriorate over time. In ideal conditions, an electric car battery should last around 10 years, however extreme temperatures, overcharging or using the battery’s minimum capacity can impact its lifespan.

What We Test And Why
Our technicians will use the latest equipment to test the battery’s voltage, starting capacity and overall condition. Our equipment measures the voltage reading, which should be no lower than 12.4v. If it is lower, this indicates that the battery requires recharging or replacing. We also test the starting capacity of the battery. If the starting capacity is below 70%, this indicates that the battery is beginning to deteriorate. It is important to note that if your car has stop/start function, it will stop working if the battery registers below 75%.
The results of a battery test will be displayed as:
- Good & Pass – Great news, no action is required. We will recheck at your next service.
- Good & Recharge – The battery is in good health but needs re-charging.
- Recharge & Retest – The battery is low, and we cannot determine its integrity until a charge is carried out. Another battery test can be performed afterward.
- Bad Battery – The battery is entering or at the end of its service life, a new battery is recommended.
