Why Do Car Batteries Die in Winter & How to Prevent It

Winter weather can be tough on your car battery. Cold temperatures significantly reduce battery performance, making it harder to start your vehicle. At TGPP-Autocare, we understand the frustration of a dead battery, especially on a frosty morning. This guide will help you understand the winter challenges your battery faces and how to keep it healthy.

Did you know?

Freezing temperatures slow down the chemical process inside a battery, reducing its ability to hold its charge.  The older a battery is, the less performance it will have and the weaker it will be. An older battery that seems fine in the warm summer temperatures will often discharge or go flat very quickly as soon as the weather turns colder. In most cases this will then lead to a non-start situation

Why Winter is Hard on Car Batteries? 

• Reduced Cranking Power

Cold temperatures significantly decrease a battery's ability to deliver the power needed to start the engine.

• Increased Electrical Demand

Winter driving increases the load on your battery with the use of heaters, lights, and other electrical accessories.

• Age-Related Decline

Older batteries are more susceptible to cold weather issues, experiencing a faster drop in performance.

Signs of a Weak Battery

• Slow Engine Cranking

The engine turns over slowly or struggles to start.

• Dim Headlights

Noticeably weaker headlight illumination.

• Clicking Noise

A clicking sound from the starter motor indicates insufficient battery power.

• Warning Lights

Some vehicles display a battery warning light on the dashboard.

Preventing Winter Battery Issues

1. Regular Battery Testing: Schedule a battery health check at TGPP-Autocare, especially before the onset of winter. We recommend testing batteries over three years old
2. Minimise Load: Turn off all unnecessary accessories (lights, heaters, audio systems) before switching off the engine.
3. Avoid Excessive Accessory Use: Minimize the use of heaters, heated seats, and air conditioning during winter.
4. Park Indoors: If possible, park your vehicle in a garage to maintain a warmer battery temperature.
5. Check for Interior Lights: Ensure all interior lights are off before leaving your vehicle unattended.
