• Provides the jolt of electricity needed to start your engine


• Stabilizes the energy supply to keep your engine running


• A good idea to replace it about every three years

The Battery in your INFINITI preserves the energy needed to start your engine. Whenever you crank your vehicle's engine, the chemical energy stored within the battery turns into the electrical energy needed to power up your essential vehicle components. And even when your vehicle is turned off, your Battery passively charges and maintains essential elements such as the car alarm or the keyless entry mechanism.

When your Battery becomes faulty, your engine might not turn on, and sometimes, you might have difficulty getting into your car using the keyless entry feature! That's why it's essential to stay alert to the the indicators of a failing Battery. You may experience dim headlights, engine backfiring, prolonged crank times, and you'll like notice a clicking sound when attempting to start your vehicle. And let's not forget the inconvenient dead battery that won’t crank or start your engine at all.

Your vehicle's battery isn't made to operate indefinitely, with many lasting at approximately 3-5 years. This is heavily dependent upon usage, weather, voltage, and more. Additionally, certain driving styles and road conditions may drain your Battery sooner rather than later.

In some scenarios, leaving certain components on when your vehicle and engine are off, such as the dome lights or accidentally leaving your doors open, may drain your INFINITI’s battery. Extreme temperatures, hot or cold, can also hinder the battery's ability to crank your engine to life. Taking short drives frequently doesn't help battery life either, since it doesn't get enough charge boost from your alternator. Finally, age and corrosion can also negatively impact your Battery.

Of course, the best time to replace a bad battery is before you and your INFINITI are stranded! Accordingly, be on the lookout for Battery issues, and steer clear of driving habits such as taking frequent short drives and leaving certain features on while your car is off. And when your INFINITI Battery requires replacement, get one made for your specific vehicle by purchasing genuine components from INFINITI Parts & Accessories.

Batteries alter in size, capacity, and type, which can make finding the right one difficult. Instead, order a genuine Battery for your INFINITI G35 2003-2007 to ensure the best fit. See the What This Fits tab for more information.
