A car battery typically lasts between 3 and 5 years, depending on usage and climate. A failing battery can leave you stranded at the worst possible time. Here are five common warning signs that it might be time for a replacement.
1. Slow Engine Crank
If your engine turns over slowly when starting, especially in cold weather, this could indicate a weakening battery struggling to deliver enough power.
2. Dashboard Warning Light
Many modern vehicles feature a battery-shaped warning light on the dashboard. If this light appears while driving, it could suggest charging issues or imminent battery failure.
3. Electrical Issues
Dim headlights, flickering dashboard lights, and malfunctioning electrical accessories (like windows or infotainment systems) can all signal a battery problem.
4. Swollen Battery Case
Excessive heat or overcharging can cause the battery case to swell. This is a clear sign that your battery is compromised and should be replaced immediately.
5. Old Age
If your battery is over three years old and you’re experiencing performance dips, it’s wise to have it tested. Many UK garages offer free or low-cost battery health checks.
Replacing your car battery at the first sign of trouble is far cheaper than dealing with a breakdown. A proactive approach saves time, money, and frustration.
