Group 35 Batteries Dimensions, Weight, Chemistry, Features

Those who are going to buy a group size 35 battery from their local store can benefit from my buying guide. It contains all the necessary factors to find the best battery for their vehicle.

However, car owners who are going to order one from Amazon can skip this part, read the product review, and choose one immediately. Without further ado, let’s get started.

What Is A Group 35 Battery?

Group 35 indicates a specific dimension that fits a limited number of car models. It is a BCI (Battery Council International) standard. Check your vehicle’s owner manual and see whether it has a group 35 battery tray or not.

Usually, Toyota, Nissan, Mitsubishi, Subaru, Acura, and some older American Cars follow this standard. It is also found in ordinary cars, trucks, and RVs. However, measuring the battery compartments by yourself can be reassuring.

According to BCI, the battery size should be around 9.0625 x 6.875 x 8.875 inches, or 230 x 175 x 225 mm. The final product can be a few mm off which is perfectly fine. These are medium-sized batteries that are capable of supporting a wide range of applications. Now, you know which batteries fall into this category. Let’s continue to the rest of the parameters.

Lithium Iron Phosphate, AGM, or Lead Acid?

When it comes to group 35 AGM battery or LiFePO4 battery, lead-acid battery, lithium wins the battle. It is due to its increased efficiency, longer runtime, more durability, greater cycle-life, and very lightweight construction.

See the product comparison chart above to see the proof. The top pick model weighs almost half of other competitor batteries. Likewise, lead-acid models lose by a mile, and that is why there are no lead-acid batteries are reviewed in this article.

Starting or Dual Purpose?

The decision to either go with high CCA-rated starting batteries or less powerful dual-purpose ones depends on the amount of power draw. If the engine requires a lot of power in the beginning and not much afterward, you should go with the starting type. In my list, Arc-Angel and Optima offer two such products. On the other hand, there are 3 dual-purpose batteries.

Battery Prices

Lastly, think about the budget. Carefully considering the specific type from the above parameters, select one from my list, and see whether you can afford it. starting around 200 dollars, I have reviewed

several models with a wide price range.

How Did I Pick?

If you search on Amazon with the term “Group 35 Batteryâ€, you will see lots of models on the result page. But I faced a problem while selecting this specific group of batteries. Lots of batteries listed on the page do not match the group 35 battery dimensions.

Those who are not careful enough can easily get deceived by the confusing reviews. So, I cross-checked every model’s dimension with the BCI standards and picked 5 models. There are also some other models besides my selection but I haven’t selected them due to their unavailability.

Modern vehicles have lots of appliances that require lots of battery power. Here, only AGM or LiFePO4 batteries can handle a wide range of applications. That is why you won’t see any lead-acid model in my final selection.

Tip: According to the manufacturer, the battery is not much self-discharging as others, which means that it can maintain the voltage even after sitting idly for a long time.

Quick Charging

Take note that this battery technology is comparatively new and users have less experience. So far, the feedbacks are positive, and you can rely on it. One issue that might bother you is the fact that the battery needs a special charger. However, it can be charged using the onboard alternators like the other models.

Due to the charging efficiency, it draws less horsepower from the alternator. Faster starting, consistent power, and improved audio fidelity are worth the high price. So, order one from the link here with the best available online price.
