• 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

Your INFINITI’s Battery preserves the energy needed to get the engine started. When you start your vehicle, the chemical energy stored in your battery turns into the electricity required to jolt your INFINITI's components into action. And even when your car is powered off, the Battery subtly powers essential elements like the car alarm or the keyless entry mechanism.

When your Battery becomes faulty, your vehicle's engine won't crank, and in some cases, you have a hard time entering your vehicle using the keyless entry feature! That's why it's important to stay alert to the the indicators a poorly functioning Battery. Some of these signs are dim headlights, illuminated check engine light, slow cranks, and hearing a clicking noise when starting your INFINITI. And let's not forget the dreaded “dead battery” that won’t crank or start your engine at all.

Car batteries aren't made to operate indefinitely, with most of their lifespans running 3-5 years. This is heavily dependent upon how much or little use it gets, weather, voltage, and more. It's also important to note that certain driving habits and road conditions might drain a Battery sooner rather than later.

For example, leaving certain accessories “on” when your vehicle and engine are off, such as the dome lights or leaving your doors ajar, may drain the power from your Battery. Extreme hot and cold temperatures, can also impair the battery's ability to bring your vehicle to life. Making frequent short trips doesn’t do your battery any favors either, since it can't get a full charge boost from your alternator. Lastly, battery age and corrosion can also negatively impact your Battery.

The most optimal time to replace your Battery is before you become isolated and stranded on the side of the road! 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 vehicle is off. And when you need a replacement, get one made for your specific vehicle by purchasing genuine OEM components from INFINITI Parts.

Batteries differ in size, reserve capacity, and type, which can make choosing the right one a bit daunting. Instead, order a genuine Battery made for your INFINITI G35 2003-2007 to ensure the best fit. Click over to What This Fits to see more information on fitment and compatibility.
