When to get a car battery test

There’s never a convenient time for a no-start situation. Get a battery test or a replacement battery at the first hint of weak starting. Pay attention to subtle signs of weakening, and if you suspect your battery is dying, visit us for a battery test.

Watch for these warning signs your battery is getting weak:

Headlights dimming or flickering while idling
Glitches in power windows, locks or any electronics
Battery voltage warning illuminated on the dash
Corrosion buildup on battery terminals
Engine clicks but won’t start
Burning rubber or rotten egg odor under the hood
Engine startup feels different than usual

TEST-PROD recommends testing the battery and charging system twice a year, especially before peak summer or winter temperatures.

Do I need a car battery replacement?

If you’ve been experiencing battery problems, we can give you a free battery test that will let you know if it holds a charge or if you need a new car battery. If you end up needing a replacement, Sun Auto Tire & Service will recycle your old car battery to reduce the impact on the environment.

Which car batteries do you recommend for lasting a long time?

Sun Auto proudly recommends and installs Interstate Batteries. Their car batteries have a decades-long reputation for high performance and long battery life, proving that they offer something unique to drivers like you who want a battery they can trust.

What’s the secret to long car battery life? Keeping new batteries charged. The Interstate system keeps its batteries fully charged, from the factory line to our service lane. To show you the difference that charging can make, they cut open two unused car batteries, both about a year old. Take a look inside:

Test FAQ

The best way to keep your car battery lasting longest is with preventative maintenance. A knowledgeable technician can check your car’s voltage, tighten fasteners, clean the battery, and apply anti-corrosion dielectric gel. Also, if you can, you should try to avoid frequent short trips. The repeated start, stop, start cycle can drain your battery’s cranking power. Other things to be mindful of include not leaving lights on or accessories plugged in and minimizing using any power when the vehicle is off.
