Car Battery Size chart: find the right car battery

Looking for the car battery size that will best fit the physical dimensions, terminal locations and type required for your vehicle. Each car battery group has numbers and letters. Group size is based on your vehicle’s make, model, and engine type. Although some cars might go with different kinds of batteries, it is important that you use a battery approved for use in your vehicle.

Car Battery types

What type of car battery is right for your vehicle?

There are two basic battery types below, wet cell and VRLA batteries. A technician at your preferred garage will evaluate your vehicle’s battery and electrical system and help you select the proper car battery group size to power your ride.

WET CELL BATTERIES

Wet cell batteries (flooded batteries) are lead-acid batteries that are specifically designed for automotive use. It is the original rechargeable battery and contains a liquid electrolyte. Some lead-acid batteries require maintenance, as the water in the diluted acid can evaporate and may need to be topped off from time to time to maintain the specific ratio of water to acid. (Note, if you refill the water at home, do not use tap water. Use distilled water.) Some modern wet cell batteries use a semi-solid electrolyte (sometimes referred to as a “sealed battery”) which does not require maintenance.

There are two popular types of wet cell batteries, SLI batteries, and deep cycle batteries.

  • SLI Battery: SLI stands for starting, lighting, and ignition. Once the engine is running, power for the car is supplied by the alternator. Most automobiles come with a generic SLI battery from the factory.
  • Deep Cycle Battery: Deep cycle batteries, also referred to as marine batteries, last longer than SLI batteries and are designed for long-term energy delivery. They are designed to be deeply discharged over and over again (which would ruin an SLI battery), and can provide a steady amount of current over a long period of time.

VRLA BATTERIES

A VRLA battery, or valve-regulated lead-acid battery, is a sealed battery with no venting of gases. These batteries are ideal for use in small spaces with no ventilation and since they’re sealed, they can be easily stored. VRLA batteries don’t leak or release hydrogen gas and are considered the safest wet cell lead-acid battery. The only drawback to VRLA batteries is that they’re sealed, leaving them unserviceable.

There are two types of VRLA batteries, the gel cell battery and the AGM battery.

  • Gel Cell Battery: Instead of containing a liquid electrolyte like a wet cell battery, a gel cell battery contains a “gelified” electrolyte. Gel batteries are tough. They’re extremely resistant to hot temperatures, spillage, physical shock, and electrolyte evaporation. Gel batteries function just like wet cell batteries, except they’re sealed and dry.
  • Absorbed Glass Mat Battery: An absorbed glass mat battery (AGM battery) is designed with the electrolyte held in glass mats, as opposed to freely flooding the plates. These glass mats are very thin fibers in the battery and are meshed together to form the electrolyte absorbed glass mat. AGM batteries work just like wet cell batteries, without the potential for spilled battery acid.

CAR BATTERY SIZES

A battery group size is an industry-standard for car batteries that indicates the actual, physical size for a car battery (height x width x length), as well as the polarity (where the positive and negative battery posts are located on the battery). This makes it easy for vehicle manufacturers to take the battery size into consideration when designing a car, truck, or SUV.

Battery group sizes provide a simplified, industry standard in automotive batteries, helping manufacturers of batteries and vehicles both reduce costs. Having standard battery group sizes makes replacing your battery at your local Firestone Complete Auto Care simple, and our technicians and automotive advisors can ensure the proper battery fitment for just about any vehicle on the road.

Helpful Hint: Instead of trying to measure the exact size of your car battery with a tape measure, look for the “Group Size” printed on the label of the battery or check your owner’s manual. You can also call or visit any local Firestone Complete Auto Care location to verify your vehicle’s correct battery replacement with the vehicle year, make, and model.
