A BCI Group 35 battery is found in many cars and light trucks. Its top-post design fits Toyota, Nissan, KIA, Ford, and other popular vehicles. Also, these batteries are commonly used in UPS, wheelchair, surveillance system backup, medical, and off-grid applications. If you’re looking for Group 35 batteries for your car or truck, this review can guide you in the right direction.

See your car’s Owner’s Manual for the most up-to-date information on whether a 35-volt battery is recommended for your vehicle. But first, you need to know how many watts does your car battery has. Even then, if you are confused or don’t know, what do battery group numbers mean? Go through our battery group size chart to ensure which battery to choose. Group 35 batteries can be hard to come by but don’t worry; I’ve got you covered with the size, features, and recommendations.

What Is a Group 35 Battery?

Group 35 batteries are medium-sized batteries with a 20-hour capacity in the 45 to 65 Ah range, delivering 620 to 850 CCA, 90 to 130 minutes RC, and so on. The Battery Council International states that a group 35 battery measures 230 X 175 X 225. (millimetres).

It is pretty similar to Group 24 Batteries. They come in various capacities. However, their electrical characteristics are determined by the battery design, intended usage, chemistry, and other factors.

They are mostly AGM dual-purpose or starter batteries. In contrast, lithium iron phosphate (LiFePO4) batteries are slowly making their way into the market for long cycle applications.

Group 35 Batteries Buying Guide: What to Look For

A few things to consider when buying a group 35 battery. Check them out right here.

Weight and Size

When selecting a group 35 battery, consider the weight and size. The greater the battery, the heavier it is. A 12V deep cycle battery typically weighs 100-200 pounds. Goal higher and obtain a bigger battery to figure out how much power you need and then pick the right batteries for your car.

Higher CCA 

If you’ve ever bought a heavy-duty battery, you’ve probably heard of cold-cranking amps. The cold-cranking amps of each group 35 battery are shown. It just means a battery can work in frigid temperatures: the more cold-cranking amps, the better. A higher CCA makes starting easier.


Even cheap car batteries are costly. It’s not possible to change the battery often. A car battery should last a decade, but it’s wise to change it every 3 to 4 years. If you want something more sturdy, a polypropylene enclosure will do. Also, buying a battery with a warranty will help you avoid costly replacements. In case it doesn’t operate as expected, it can be returned.

Reserve Capacity

When a car battery is totally exhausted, the engine stops, and the automobile breaks down. It can happen anywhere, at any time. To avoid this, get a car battery with more backup capacity. If your car battery dies, you can drive to work using the reserve capacity.

Battery Age

The age of the battery is an essential factor that most people neglect. It’s the time between manufacture and purchase of a group 35 car battery. Batteries get better with age. Preferably a battery made within the last six months. Look at the alphanumeric code to find the battery’s manufacture date. Months are represented by letters A-L, and years by numerals 0-9.
