MAZDA Parts Explained: The Battery

Mazda battery service


Today’s Mazda cars contain hundreds of Mazda parts, and one of the most important is the battery. It’s the beating heart of your car, and if it isn’t working right, your car won’t run. Sentry West Mazda introduces you to this key component, covering what it does, how to take care of it, and signs of battery trouble.

What Does a Battery Do?

The battery has two key responsibilities in most vehicles. The first is to provide the initial electrical energy needed to start the engine. The second is to power electrical systems such as the lights and your phone charger when the engine is off. In a plug-in hybrid model like the 2025 Mazda CX-70 PHEV, the battery is even more important, as it’s the sole source of power when all-electric driving is engaged.

How Do You Take Care of a Battery?

Here are three important ways that you can care for your car’s battery and maximize its performance and longevity:

  • Conduct regular visual inspections for cracks, leaks, or corrosion on the terminals. You’ll also want to have the battery tested regularly at our Shrewsbury, MA, Mazda dealership, which is especially important as the battery gets older (around three to five years).
  • Combine errands into a couple of long trips instead of several short trips. The latter won’t allow the alternator enough time to fully recharge the battery, and over time this will reduce performance and lifespan.
  • Avoid using accessories such as the lights, radio, and phone charger when the engine is off, as it can drain the battery.

Signs of Battery Trouble

Signs of battery trouble come in several forms. Three of the most common are:

  • A clicking sound when turning the key in the ignition: the battery could either be low on power or dead. 
  • Dim or flickering headlights: the electrical system isn’t getting enough power from the battery. This could be due to battery corrosion.
  • Strong, rotten-egg smell around the battery: the battery is leaking sulfuric acid and needs immediate attention.
