Mobile battery testing and replacement

Signs of a weak battery

• Slow engine cranking
• Clicking when the key or start button is used
• Repeated jump-starts
• Electrical systems resetting
• Battery warning or charging concerns
• Older battery with declining performance

Why testing matters

Replacing a battery without checking the wider system can miss an alternator problem, parasitic drain, loose terminal, poor connection or starter issue. Vehicle requirements also vary, particularly where battery registration or stop-start systems are involved.

Choosing the correct replacement

The battery must meet the vehicle’s size, terminal layout, capacity and technology requirements. Stop-start vehicles may require AGM or EFB batteries rather than a conventional replacement.

Battery safety

A swollen, leaking, extremely hot or strongly smelling battery should not be handled casually. Keep sparks and flames away and seek professional assistance.
