When To Have Your Battery Checked

• Slow or hesitant engine cranking, especially first thing in the morning
• Clicking sound when turning the key or pressing the start button
• Dashboard battery/charging warning light illuminated
• Dim headlights, weak horn, or sluggish power windows and accessories
• Corrosion on terminals, swollen battery case, or acid odor
• Recent need for a jump-start or battery more than 3–5 years old

Our Diagnostic Process

Battery problems are often symptoms of deeper electrical issues. Our specialists run a complete system evaluation to ensure an accurate fix the first time.

• State-of-Health & Load Test: Measures cranking amps and overall battery condition under load.
• Charging System Test: Verifies alternator output, voltage regulator function, and ripple voltage.
• Starting System Test: Checks starter draw and voltage drop across critical cables and grounds.
• Parasitic Draw Test: Identifies excessive key-off current caused by modules, accessories, or wiring faults.
• Terminal & Cable Inspection: Finds hidden corrosion, loose connections, and damaged wiring.

Battery Repair & Replacement Options

After diagnostics, we explain your options clearly and recommend the solution that best fits your vehicle and driving needs.

• Professional Cleaning & Service: Terminal cleaning, anti-corrosion protection, and secure fitment.
• Cable & Terminal Repairs: Replace worn terminals, repair or replace damaged cables and grounds.
