7 Signs Your Car Battery Needs Replacing

A car battery rarely dies overnight. Here are the seven most common warning signs UK drivers see — usually weeks before total failure.

• Slow, laboured cranking when you turn the key
• Dashboard battery or charging-system warning light
• Start-stop suddenly disabled (often the earliest sign)
• Dim headlights at idle, brightening as you rev
• Electrical glitches: clocks resetting, infotainment rebooting, key fob range dropping
• Battery visibly swollen, leaking, or corroded around terminals
• Battery age of 4+ years combined with any of the above

Any two of these symptoms together is a strong sign it's time to replace. We can come to you and test free of charge before you commit.
