Group 26R vs 35 Car Battery

The battle of group 26R vs 35 car battery has become a talk of the town among car enthusiasts, as two top contenders face off in a race to the top.

Group 26R cells boast a higher capacity than their 35 counterparts, but they also require more time to fully recharge. Will these aging cells be capable of keeping pace with the new generation?

In recent years, the group 26R battery has become a popular choice among most modern car owners. This battery is said to be more environmentally friendly and durable than the traditional car battery.

However, there are some people who believe that the group 26R battery is not as strong as the traditional car battery.

So, who should you believe? The experts? Your gut? Or maybe a little of both? When confronted with two certain choices, it’s often helpful to consider what each one has to offer.

In this article, we will compare the two types of batteries and see who will win in the battle for car owners’ hearts and wallets.

What is Group 26R Car Battery?

Group 26R car batteries are a type of lead-acid battery that is commonly used in automobiles. The letter “R” in 26R battery group stands for the terminal position, which indicates it has the positive terminal on the right.

They have been popular for their high capacity that can be discharged gradually. Group 26R batteries are also known as wet cell batteries.

What is Group 35 Car Battery?

Range 35 represents a BCI number, which represents the physical dimension of a battery. This battery size is standardized and is used by manufacturers in vehicles.

Group 26R vs 35 Car Battery – Factors to Compare

Group 26R and 35 car batteries are both designed to provide power for a vehicle. Both have numerous characteristics that set them apart for a particular kind of item. However, they also have some differences that should be considered when choosing which battery to purchase. Here we’re going to compare some of the important factors of these two battery sizes:


Group 26R batteries account for the smallest nominal dimensions of (L x W x H) 8 3/16 x 6 13/17 x 7 3/4 inches (8.1875 x 6.8125 x 7.75 inches, 208 x 173 x 197 mm), with a total mass approximating 28 pounds (12.7 kg).

In contrast, the collective dimensions of the group 35 batteries often measure out to about nine 1 6 x 6 7 8 x 8 7 8 inches (9.0625 in × 6.875 in × 8.875 in, 230 mm × 175 mm × 225 mm). We ought to be keen to pay particular attention to this as we often observe that a number of group 35 battery cells are somewhat longer than the ‘standard maximum length.

Cold Cranking Amps and Reverse Capacity

When you’re in the market for a new car battery, it’s important to consider the cold cranking amps (CCA) and reverse capacity (RC) of each model.

The CCA is how many times the battery can be charged at 0°C (32°F) before it starts to drop in capacity. Whilst, the RC rating is the measurement of how much electricity a battery can store when discharged to 1% of its capacity.

The 26R battery has a CCA of 950 and an RC of 100,000. This means that it can be charged 9 times at 0°C before it begins to lose power and can store 10,000 electrical volts when discharged.

The 35 Car Battery has a CCA of 1400 and an RC of 200,000. This means that it can be charged 14 times at 0 C before it begins to lose power and can store 2,000 electrical volts when discharged.

Usage of the batteries

The 26R is typically found in small to medium-sized cars, while the 35 Car Battery is more commonly used in larger cars. The 35 Car Battery is the second most common battery size.

This size battery can be found in a lot of cars and is usually located under the hood of the car. However, there are some exceptions to this rule, of course, and there are also hybrid and electric cars that use different battery sizes altogether.

Replacement in between

You know that any battery that’s greater than 35 in size will also make use of a larger tray than your 26R battery currently uses. Therefore, if you are already using 35 batteries, you can replace them with 26R batteries in just a couple of minutes without any cutting or altering to your existing battery tray.

However, if you’re using a 26R battery and want to move to a 35 battery, check the tray of the existing battery to see if it has any extra space. If it does, the volume of both batteries may be sufficient to replace the 26R. If the tray doesn’t fit, the shape may need to be changed.

Group 26R vs 35 Car Battery – Which one is right for you?

Both 26R and 35 batteries have their own strengths and weaknesses, but they both offer some great features that can make your driving experience better. What would be best for you will depend on what you’re looking for and need from it.

When you’re buying automobile batteries, there are a few factors to keep in mind. The size of the battery, the type of car you have, and even your lifestyle can all affect which battery is right for you.

If you’re in the market for a new battery, here’s a look at two of the most popular options: group 26R and group 35.

First up is group 26R. This type of battery is typically used in smaller cars that don’t require as much power or torque, like Hondas and Toyotas. They’re also good for people who use their cars sparingly or for short trips.

On the other hand, group 35 batteries are more common in larger cars like Ford Focuses and Chevrolet Malibus. They’re better suited for drivers who need more power and torque, especially if they plan on using their car for long trips.
