The Infiniti G-series came into its own in 2002 when the G35 was first released.
Its powerful V6 engine and solid reliability made it a popular entry-level sports coupe/sedan, and lead to a follow-up model, the G37, which was released in 2009.
Because these are relatively powerful cars, the Infiniti G-series needs a battery that can adequately fulfill its power supply criteria.
Today, we’ll be looking at four of the best batteries you can buy that are compatible with the G35 and G37.
Top 4 Best Batteries For Infiniti G35 And G37 Reviews
With so many battery options available, it can be pretty hard to pick the right one for your needs. To that end, I’ve compiled a list of four of the best batteries you can buy for your Infiniti G-series.

3. Optima Batteries 8020-164 35 RedTop Starting Battery
The Optima RedTop is a powerful battery that should be able to start your Infiniti G-series no matter what the weather is like.
It features a spiral cell design, which enables the battery to achieve greater levels of deep cycling over its lifetime.
The RedTop is powerful yet lightweight, which is always something you should look for in a car battery.
Because of its relatively small size, it is also quite versatile; this battery can be mounted in a variety of vehicles, not just the G-series.
It also features very strong vibrational resistance compared to some similar batteries.
Overall, the features of the RedTop make it one of the better options currently available if you’re in the market for a new car battery.

4. Delphi BU9035 MaxStart AGM Premium Automotive Battery
The Delphi BU9035 has a solid CCA rating as well as a solid reserve capacity, making it a good battery for use in cold weather conditions, even in a car like the G-series with a relatively large V6.
Even cars that are loaded with tons of power-draining accessories should have no problem starting up every time if you have this battery installed.
The BU9035 also has a long shelf life, so it can go for long periods without being used.
Like the other batteries we’ve mentioned, the BU9035 comes in a spill-proof design and offers strong resistance to corrosion and vibrational stress.

Now that we’ve gone over our product reviews, let’s check out some commonly asked questions about car batteries that you might find helpful.
What Does “CCA” Mean?
“CCA” is short for “cold-cranking amps”, and it refers to how well your battery will perform in cold conditions.
A car battery’s CCA rating is calculated by determining how many amps the battery can deliver for 30 seconds at 0° Fahrenheit; it also has to display a consistent voltage of at least 7.2 volts during this time.
CCA ratings are more important if you live in a region that is regularly affected by sub-zero degree temperatures.
Do All Car Batteries Have The Same Voltage?
These days, that is the case; modern car batteries are standardized for an output of about 12 volts.
Some cars used to come with 6-volt batteries and 6-volt electrical systems, so bear this in mind if you happen to own a classic car.
Hybrid vehicles often contain a separate, higher-voltage battery that can produce up to 300 volts.
How Do I Replace A Car Battery On My Own?
It’s relatively easy to change a car battery by yourself. All you really need to do is disconnect the power cables, and then remove the clamps attaching the battery to the tray.
Then it’s just a matter of swapping your old battery out for your new one and then connecting everything again.
Since disconnecting your car’s battery can sometimes reset your car’s memory settings, it’s a good idea to attach a battery saver to your car before swapping your battery.
If you don’t, you may have to set the time on your clock again, readjust the position of your seats and side mirrors, and do all sorts of inconvenient things.
Despite their size, car batteries can be deceptively heavy, so use caution when changing a car battery.
What Factors Should I Consider When Buying A New Battery?
You should consider a few things before buying a new car battery, which include:
There are multiple battery size groups, and it’s important to find out which one your car was built to accommodate before going out and buying any battery.
The Infiniti G-series is compatible with both Group 26R and Group 35 battery sizes.
2. Production Date
Ideally, when buying a replacement battery for your car, you should look for one that was manufactured fairly recently.
Batteries that have been sitting for a long time will lose some of their charge, and it’s never preferable to buy a battery that isn’t already at close to full capacity.
Look for a date of manufacture printed somewhere on your battery if you want to find out how old the battery is.
Before selecting a battery, consider how much maintenance you intend to perform on your car regularly; some batteries require more maintenance than others to keep them in working order.
If you don’t mind periodically filling up your battery with water, then by all means get a high-maintenance battery; but if this seems inconvenient to you, then consider another type of battery.
4. Reserve Capacity
This refers to how long a battery can continue to produce power until it is completely discharged.
In general, you want to look for a battery with a high reserve capacity, so you don’t have to worry as much about running your accessories with the car off for prolonged periods of time.
It’s not always easy to find a good replacement car battery, no matter what kind of car you have.
There are plenty of options out there, and you may feel overwhelmed when presented with this much variety, especially if you aren’t familiar with the differences between various batteries.
However, with the information I’ve shared with you today, you should have no trouble picking the right battery for your Infiniti G-series (or any other car you happen to own).
