Car Battery Buying Guide – Things to Consider When Buying a Vehicle Battery


Our daily lives run more smoothly when our car batteries are in good shape, but just like anything else, a car battery can't last forever and ultimately needs to be replaced. It's not usually the best idea to wait until the car breaks down due to a dead battery, but that's precisely what most of us would do. A dead automobile battery spells danger on a frigid winter day.

Your car's battery is its beating heart. It transmits the power in a chemical form, which is then converted into electrical energy and used to control the vehicle's electrical components. If power items are turned on after the engine is turned off, car batteries might become old or fail.

Choosing the correct car battery can be challenging at times. The following pointers will assist you in making an informed decision and make your battery purchase less stressful.

Examine the Battery's Manufacturing Date

Always go with a new car battery. How? Check for the date stamp on the battery set's top cover. The date is displayed as a two-character code, with the letter representing a month and the number representing the year of manufacture. 

For instance, if the battery reads B5, the letter B denotes the month of February, and the number 5 indicates the year 2025. Call your installation service provider for assistance if you're having trouble locating the production date. Installing a battery set over six months old is strictly prohibited.

Determine the Size of Your Battery Group

Car batteries are classified based on their length, breadth, and height. The number can be found on the battery label if you own a car with its original battery. Group size is usually a two-digit number followed by a letter. 

Otherwise, contact your owner's manual (search under the specs section) or a professional to determine the appropriate size for your car. When driving on roads with vibrations, a battery of the correct size should fit precisely in the battery tray and feel secure, so it does not move and is not harmed.

Capacity Reserve

This is the amount of time the battery can run without the help of the engine before being discharged. A high Reserve Capacity helps the car get through difficult situations like a non-compliant engine, alternator failure, and leaving lights on by accident.

Power Consumption

The terms Cold Cranking Amps (CCA) and Cranking Amps (CA) are interchangeable (CA). Cranking Amps refers to the energy necessary to start a vehicle at 32 degrees Fahrenheit, whereas Cold Cranking Amp refers to the battery's capacity to create a car at 0 degrees Fahrenheit. CCA is important in cold locations; therefore, more excellent CCA batteries are preferred.


A valid guarantee always covers branded batteries. Even if it's available at a discount, don't buy a locally-made battery. Unauthentic storms don't come with a warranty, don't work with features, and don't last very long. Choose a brand that gives the longest free replacement time by searching the internet or speaking with your battery provider.

We recommend getting a battery with at least a 24-month warranty. Most reputable battery manufacturers will provide a 24-36 month warranty. When Best Batteries' batteries are fitted to the vehicle's specifications, they come with a guarantee that is exactly this long. 

The Old Battery should be Recycled

Car batteries are easily recyclable and can be reused to create new goods. When purchasing a new battery, you will certainly be charged an additional fee, which will be returned if you bring in your old battery.


There are two types of maintenance situations here: low maintenance and maintenance-free. The liquid electrolyte in a maintenance-free automobile battery is normally sealed, and it can run for the whole battery life without needing to be replaced.

Low-maintenance batteries have caps that can be unsealed to allow distilled water to be added regularly.

High capacity

The bigger the capacity, the longer the power will be accessible and the more beneficial it will be when your car's alternator fails, or you've left the lights on for an extended period. Higher capacity batteries will not be affected by a drop in charge because they will power for longer. 

As a result, select a battery with a bigger reserve capacity. They may be a little pricey, but you will always reap the benefits.

Storage Capacity

Every vehicle has a specific power need for which the battery is selected. This determines the battery's storage capacity, measured in Ampere-hours or Ah. The higher the Ah, the longer the battery can keep up with the load.

Previous battery experience

Consider your previous experience with the battery type before purchasing one. A battery that has been reliable for a long time is better, and you can always compare your experience with that of your friends.

Follow the owner's handbook for the specifications required when purchasing a battery for automotive or other purposes, or see an expert. 

If you drive the same car for more than three years, you're likely to need to replace your old car battery, as batteries last on average for three to four years before dying. It might also include flaws like a cracked case, loose battery connectors, or missing filler caps. Regardless of whether the scenarios mentioned above apply to you, it's critical to have the correct battery for your vehicle.
