If your car is struggling to start on cold mornings, you’re not alone. Low temperatures reduce the capacity of batteries and increase demand on your electrical system, making winter the peak season for battery failures.
We’re going to cover why this happens, and what you can do about it.
Why does the cold affect your battery?
Car batteries rely on chemical reactions to produce electrical power. When the temperature drops, those reactions slow down dramatically – which means your battery simply can’t deliver the same amount of energy it does in warmer months.
This is then exacerbated by the fact that you often need more electrics in winter – heated screens, headlights, AC, heated seats. These all place extra demand on your battery.
How can I reduce the risk of battery issues?
Sometimes, a battery can stop working because it’s reached the end of its lifespan. Most last between 3-5 years, so as you reach the 4 year mark it’s more likely to struggle in winter.
Here’s some quick tips to improve battery health:
- Avoid lots of short trips – this doesn’t give the alternator time to recharge
- Avoid using electric components when they’re not necessary
- Get a battery health check
The warning signs
Whilst some of these signs aren’t a sure-fire sign that your battery is responsible, they’re good indicators that you should probably get it checked.
- If your car is taking longer than usual to start
- Dim lights
- Electrics slowing down – such as windows moving slowly or a weaker fan
- Dashboard warning light
Why a battery health check helps
Sometimes, it’s hard to tell if a car component is struggling yourself when you’re not trained in mechanics. For peace of mind, many people decide to visit a garage like Bodymek for a health check.
A garage can not only test your battery, but also your alternator. This is a key indicator to see whether your battery is the issue, or the charging.
Winter is tough on car batteries, and a failure at the wrong moment can leave you stranded in freezing temperatures. By understanding how cold weather affects your battery, recognising the warning signs, and taking preventative steps, you can avoid most common winter battery problems.
A quick check at your local garage – or even simple at-home precautions – can make the difference between a smooth start on a frosty morning and an unexpected breakdown. Get in touch for your battery health check.
