Starting Battery Diagnostics, Testing & Replacement at MB Automotive

Alternator Replacement

Your alternator plays a crucial role in powering your vehicle while driving by recharging the battery and supplying electricity to your electrical system. A failing alternator can cause even a brand-new battery to die quickly. Our skilled technicians perform thorough voltage output testing and replace your alternator with a high-quality OEM or aftermarket unit when necessary.

Battery Testing & Replacement

Car batteries generally last between 3 to 5 years, depending on climate, driving habits, and battery quality. We provide comprehensive battery testing to assess health and performance. When a replacement is needed, we carry a wide selection of high-performance batteries for domestic, foreign, and European vehicles. We also handle professional installation and environmentally responsible disposal of your old battery. 

Starter Motor Replacement

The starter motor initiates your engine’s operation by turning it over. If you hear clicking noises or your engine fails to start, your starter may be failing. MB Automotive inspects your starter motor and replaces it using parts that meet manufacturer specifications to ensure smooth, reliable starts every time.

Complete Starting & Charging System Diagnostics

Using advanced computerized diagnostic equipment, we test every component of your vehicle’s electrical system-battery voltage, alternator output, starter draw, and charging rates. This detailed analysis enables us to provide an accurate diagnosis and transparent recommendations for repair or replacement.

To help maintain your vehicle’s starting and charging system:

• Regularly check your battery terminals for corrosion
• Start your vehicle frequently if it sits unused for long periods to keep the battery charged
• Replace your battery every 3-5 years or sooner if you notice performance issues
• Avoid overloading your electrical system with aftermarket devices
• Keep the alternator belt tight and inspect it for wear
