Guide to Buying a Car Battery

The day your car does not start is not the best time to buy a new car battery. But according to our research, that is exactly what most people do.

You will need to replace the car battery once or twice during the lifetime of your car as it gets old or worn out due to heat exposure and repeated charging. 

A dead battery can be a real problem, especially if you do not get your jumper cords or have to wait for road help.

Taking care of your battery can help you get a longer service life from it, and paying attention to its status and age can indicate that it’s time to start buying one … before you are left out.

Below are some tips to find the best battery for your needs. (Best automotive tips)

Get the Best Battery for Your Car

We test, evaluate, and compare the latest car batteries to keep you fully charged.

Check Under the Hood

Paying attention to battery retention and vigilance as the replacement period approaches will ensure that you can choose to replace it with your own conditions, which include careful research and proper planning.

Check Batteries Annually

Testing should be part of the owner’s approach, but it is very important to check before taking a long road trip.

Car batteries usually last from three to five years, according to the AAA, from 58 months or more in the farthest reaches of the northern U.S., dropping to less than 41 months in the southern hemisphere.

While almost all modern car batteries are “non-repairable,” we recommend that your battery be tested by a mechanic every year when you are 2 years old if you live in a warm environment or 4 years if you live in a cold environment. 

Doing so tests its ability to hold the voltage while in use, and the results will inform you when it’s time to start buying.

Battery age is also a strong indication that it is time to consider a replacement. The date can be found on the sticker attached to the top or side of the battery. The battery made October 2021 will have a numeric code 10/21 or the K-1 alphanumeric code. “A” is January, “B” is February, etc. (letter “I” skipped).

Battery Should Be Equal To Your Car & Driving Needs

Car batteries come in many sizes. Among those we have explored, there is a big difference where there is the best player every year, and from size to size. 

This makes it difficult to make simple recommendations for a product or model. It also means you should not assume that buying the same battery model you are replacing will get you the same results.

Make sure you get the right size and storage space (or type) for your car. Check your owner’s manual or relevant store reference before purchasing.

In some cases, owners may replace the AGM battery with a standard one with floodplains to extend the long life in the tropics, but it is best to consult a mechanic first. 

Many vehicles come with AGMs to support the growing network of electrical components, and the charging system may be directly equipped with an AGM battery.

Make sure the New Battery

Batteries lose power over time, even when stored. To make it work better, buy less than 6 months old. Three months is even better. Most have a shipping code. Some use the monthly letter (“A” of January) and year number (“1” for 2021); others use the date date.

Reuse Your Old Battery

Toxic and acid batteries can be easily recycled, and many retailers will waste old. When you buy a new battery at the store, you will probably pay extra for the replacement when you replace the old battery.

Compare Credentials

It is important to choose the battery with the longest free replacement you can get. The battery warranty is calculated in two terms: free replacement time and limited duration — allowing for partial replacement. 

The 24/84 code, for example, shows a free exchange period of 24 months and a separate 84-month warranty. But the refund will usually decrease immediately if you are within the time limit.

Note that signs of neglect — such as low water levels and improper installation — may invalidate the warranty period. As well as heavy use, such as high-end car sound and marine applications, if the battery can be recommended for it.
