Battery issues are a common complaint from car owners during the winter months. Dewald Ranft, chairperson of the Motor Industry Workshop Association, in proud association with the Retail Motor Industry Organisation, explains: “As it gets colder, it becomes harder for the engine to turn over because the oil inside the engine thickens, which demands far more current from a battery, and the battery cannot produce its normal amount of energy because of the cold.”
Cold cranking power
As temperatures drop, engine oil thickens, requiring more power from your battery to crank the engine.
- Cold weather also reduces a battery’s ability to produce its normal energy output.
Warning signs
A grinding or clicking ignition sound often indicates a weak battery.
- Headlights dimming at idle, then brightening with revs, are another red flag.
- Slow engine cranking when starting is a cause for concern.
Maximise battery life
While batteries typically last three to five years, various factors can affect their lifespan:
- Climate
- Driving habits (distance and frequency)
- Electronic accessory usage
- Remember, even parked cars use battery power for features like clocks and security systems.
- Unplug phone chargers, tablets and other devices when not in use, especially when the car is off. Doing so prevents continuous power drain.
Winter battery care tips
- Replace batteries over five years old showing starting issues.
- Double-check that all interior lights, boot lights and radios are switched off before parking overnight.
- Turn off electronics when starting a cold car to minimise strain on the battery.
Get a battery checkup
If you’re unsure about your battery’s health, visit an accredited workshop for a simple battery check.
Don’t wait for a breakdown – proactive maintenance will keep you on the road.
By following these tips, you can ensure your car starts reliably all winter long. Remember, prevention is key!
