How do I know what size car battery to buy?
The first step in determining what size battery you need is to check your vehicle’s owner’s manual. The manual will provide you with the specifications for the battery that is recommended for your make and model. If you don’t have the manual, you can also check the battery that’s currently in your vehicle. The battery will have a label that includes the group size, cold cranking amps (CCA), and reserve capacity (RC).
What are the sizes of car batteries?
Car batteries come in a range of sizes, but the most common sizes are grouped by the Battery Council International (BCI). The BCI group size is based on the physical dimensions of the battery, such as length, width, and height. Here are the most common BCI group sizes:
– Group 24: 10.25 x 6.8125 x 8.875 inches
– Group 35: 9.0625 x 6.875 x 7.875 inches
– Group 48: 10.875 x 6.875 x 7.875 inches
– Group 65: 12.0625 x 6.875 x 7.5 inches
– Group 75: 9.4375 x 7 x 7.5 inches
– Group 78: 10.875 x 7 x 7.5 inches
How big is a 12V battery?
Most car batteries are 12-volt batteries, which means they provide 12 volts of power to your vehicle’s electrical system. The physical size of a 12-volt battery can vary depending on the BCI group size, but they typically range in size from 9-13 inches in length, 6-7 inches in width, and 7-9 inches in height.
How do you measure battery size?
To measure the size of your car battery, you’ll need to measure the length, width, and height of the battery case. It’s important to measure the case and not just the top of the battery, as the case is what determines the group size. Once you have these measurements, you can compare them to the BCI group size chart to determine the correct size battery for your vehicle.
In conclusion, choosing the right size car battery is crucial for your vehicle’s performance and safety. By checking your owner’s manual or current battery label, understanding BCI group sizes, and measuring the battery case, you can confidently select the correct size battery for your vehicle.
