When purchasing a battery, you will see a series of numbers and letters in the name. These numbers and letters are the BCI group size of the battery. BCI is the most common system used to classify battery group sizes. The following battery group size chart explains the most common BCI battery groups and their specifications. When choosing a battery, it is important to use the ones that are recommended by the manufacturer for your make and model of the vehicle. The easiest way to find out what battery group you. First, each vehicle comes with a specific battery tray size, whether it's a car, truck, SUV, commercial vehicle, boat, recreational vehicle, or other vehicles. It is important to choose a battery that has a snug fit in the tray. Otherwise, the battery could move around and. The BCI designationsinclude the group definition, dimensions, measurements, types, sizes, and other characteristics. The battery conversions chart.

What identifies a battery as a certain group size?
There are four characteristics that identify a battery as a certain group size. The first is the size of the battery, and more specifically the dimensions. Batteries within a certain group size must be the same physical size (i.e., within 2mm) in order to ensure the proper fitment in a vehicle.
How are batteries classified?
Lastly, batteries are classified into group sizes by chemistry. By default, the battery is assumed to use lead chemistry with flooded technology. Designations are assigned for higher-performance variants including EFB (enhanced flooded battery) or AGM (absorbed glass mat).
What is the most common battery group classification system?
Although BCI is the most common battery group classification system in the United States, others do exist. EN and DIN are other battery group classification systems that you will sometimes see in owner's manuals or when shopping for batteries.
What is a battery list?
The first list is a battery classification by size and format. Then, the primary (non-rechargeable) and secondary (rechargeable) cell lists are lists of battery chemistry. The third list is a list of battery applications. The final list is a list of different battery voltages. Today, one of the most common batteries is the lithium-ion battery.
What is the difference between a BCI and a side post battery?
Top post batteries have terminals on top. Side post batteries have them on the sides. The BCI system makes sure the battery fits your car's terminals. BCI group sizes also list voltage and capacity. A Group 27 battery is 12-volt and has 70 to 100 Amp-hours (Ah). Group 31 batteries can have up to 120 Ah or more.
Other examples include group U1, which are intended for utility vehicles, and Group GC8, which is designated for golf carts. It lists many different battery groups that are designated for automotive and light truck uses, which come in many different shapes and sizes. What if I Can't Find The Right Battery for My Group?
