Why Winter Is Tough on Car Batteries and How to Prepare
Winter can be especially harsh on your car battery. The combination of freezing temperatures, increased energy demands, and extended periods of inactivity can push even the healthiest battery to its limits. At Andrews Car Centre in Lincoln, we know how important a reliable battery is during the colder months. This guide will explain why winter affects car batteries and how you can prepare to keep your vehicle running smoothly.
Why Does Winter Affect Car Batteries?
Cold weather presents unique challenges for car batteries due to the following reasons:
1. Reduced Chemical Activity
Car batteries rely on a chemical reaction to generate electricity. As temperatures drop, this chemical process slows down, reducing the battery’s ability to hold and deliver charge. At 0°C, a fully charged battery operates at about 65% efficiency, and at -18°C, that drops to just 40% efficiency.
2. Increased Power Demands
Winter driving requires more power from your battery because:
- Cold Starts: Starting a cold engine takes significantly more energy due to the thickened engine oil.
- Heated Features: Using heaters, defrosters, and heated seats increases the electrical load.
- Short Trips: Frequent short journeys prevent the alternator from fully recharging the battery.
3. Impact of Older Batteries
If your battery is already weak or nearing the end of its lifespan (typically 3–5 years), the added strain of winter can cause it to fail altogether.
Signs Your Battery May Struggle This Winter
Watch for these warning signs that your car battery might need attention:
- Slow Engine Starts: The engine cranks sluggishly or struggles to start.
- Dim Lights: Headlights or interior lights appear weaker than usual.
- Warning Lights: A battery or electrical warning light appears on your dashboard.
- Corroded Terminals: Visible white or green residue on the battery terminals.
If you notice any of these symptoms, it’s best to have your battery inspected promptly.
How to Prepare Your Car Battery for Winter
Taking a few simple steps can help ensure your car battery stays reliable during the colder months:
1. Get a Battery Check-Up
At Andrews Car Centre in Lincoln, we offer car battery checks to assess your battery’s health. Our technicians can measure its voltage, capacity, and ability to hold charge, ensuring it’s ready for winter.
2. Keep the Terminals Clean
Corrosion on the terminals can interfere with the battery’s performance. Clean the terminals with a mixture of baking soda and water, and apply a thin layer of petroleum jelly to protect against future corrosion.
3. Park in a Garage or Sheltered Area
If possible, park your car in a garage or under shelter to protect it from extreme cold. Using a battery blanket or insulator can also help keep the battery warm.
4. Avoid Frequent Short Trips
Plan your journeys to avoid excessive short trips. Longer drives allow the alternator to recharge the battery more effectively.
5. Reduce Electrical Load
Turn off electrical features, such as heated seats or defrosters, once your vehicle has warmed up. This conserves power for essential functions like starting the engine.
6. Carry Jump-Starting Equipment
Invest in a good-quality set of jump leads or a portable jump starter to prepare for emergencies. Knowing how to safely jump-start a car can be invaluable in winter.
