Choosing the Best Car Battery—Buying Guide

Selecting the right car battery for your vehicle involves understanding that while combustion engine cars operate similarly, they don’t all accept the same car battery. Batteries vary greatly in shapes and sizes, and appreciating these fundamental differences is crucial. When it’s time to purchase a new battery, key specifications to consider include the battery type, group size, reserve capacity (RC), and cold cranking amps (CCA). Each of these specifications plays a vital role in ensuring that the battery you choose is the perfect fit for your vehicle’s needs, both in terms of size and performance.

Battery Type

When choosing a car battery, understanding the three main types is crucial. The standard lead-acid (SLA) battery is a traditional choice, more common in vehicles manufactured before 1980. Despite its longevity, it requires regular maintenance due to its toxic and corrosive nature.

The absorbed glass mat (AGM) battery, on the other hand, represents a safer and more advanced option. It’s maintenance-free, with fiberglass mats absorbing the acid, thus enhancing its durability against vibrations and spillages. Preferred in modern vehicles, AGM batteries offer a long lifespan and can handle more power compared to standard flooded batteries.

Lastly, the lithium-ion battery is gaining traction, especially in electric cars. Known for being lighter and smaller, these batteries are maintenance-free and boast a rapid recharge rate, making them increasingly popular in today’s automotive market.

Group Size

When selecting a car battery, one crucial aspect to consider is the group size. Manufacturers categorize batteries into different group sizes to simplify the selection process. To find the right battery for your vehicle, simply refer to your vehicle’s owner’s manual to determine the approved battery size. Then, choose a battery that falls within that same group. Common group sizes include numbers like 35, typically used in brands like Mazda, Toyota, and Honda, or 48/H6, commonly found in luxury vehicles like Audi, BMW, and Mercedes-Benz. This straightforward approach ensures compatibility and optimal performance for your vehicle.

Reserve Capacity (RC)

Reserve Capacity (RC) is a crucial specification to consider when choosing a car battery. It indicates the number of minutes the battery can sustain the car’s electrical system in the event the alternator stops working. This feature is especially important in modern vehicles that heavily rely on computer systems. A battery with a high RC ensures that your vehicle has enough backup power to keep essential functions running, even when the main power source is compromised. Therefore, understanding and evaluating the RC is key to finding a battery that reliably supports your vehicle’s needs.

Cold Cranking Amps (CCA)

Cold Cranking Amps (CCA) is a crucial term to understand when selecting a car battery. It essentially measures the battery’s power output, focusing on its capability to turn over a cold engine. A higher CCA value indicates a more powerful battery, which is especially important for starting vehicles in cold weather. When replacing your car battery, it’s advisable to match the specifications of the new battery with those of the old one. You can usually find these details on your existing battery’s label. This approach ensures that the new battery is compatible with your vehicle, optimizing performance and reducing the risk of any potential damage.


Lithium batteries are the best in quality, offering the highest energy density and excellent performance in extreme temperatures.

Lithium batteries are the most powerful, offering the highest energy density and storing more energy than other types like alkaline.
