Battery Testing & Diagnosis
Not sure if your battery is dead or something else is wrong? Our mobile battery testing and diagnosis service helps you find out fast — without towing your car to a shop.
We bring professional-grade diagnostic tools directly to you, test your battery health, and evaluate the full starting and charging system to pinpoint the problem on the spot.
What’s Included in Our Battery Testing
- Battery voltage and cold cranking amps (CCA) check
- Visual inspection of terminals and corrosion
- Starter draw test
- Alternator output test
- Full mobile diagnostics, delivered at your location
If the issue is just a weak battery, we’ll jump it or replace it right then and there. If it’s something deeper, we’ll explain your options clearly — no upsells or guesswork.
Signs You Might Need Battery Testing
Not all battery failures are obvious. If you’re seeing any of these symptoms, it’s time to get your system tested before you end up stranded:
- Slow engine crank
- Dim dashboard lights or headlights
- Clicking noise when turning the key
- Frequent need for jump starts
- Battery more than 3 years old
Mobile Diagnostics: How It Works
Our technician arrives with industry-standard diagnostic tools, safely accesses your battery and electrical system, and tests each major component in just minutes. You’ll get clear answers and real data — not guesswork.
Everything is done at your home, office, or wherever your vehicle is parked. You stay in control the entire time.
What Happens After Testing?
If your battery is still healthy, we’ll explain the likely cause of your issue. If your battery is weak or failing, we can install a new one immediately — no second appointment needed. See our Mobile Battery Replacement page for more info.
If it turns out to be a deeper issue with your alternator or starter, we’ll provide a diagnostic report to help guide your next steps.
Still Stuck? You Might Just Need a Jump
If your battery is drained but not damaged, a safe jump start could be all you need. Check out our Jump Start Service to get moving again in minutes.
