Best Car Batteries For Hot Weather With Buying Guides

Car batteries for hot weather are specially designed with heat-resistant properties to withstand high temperatures. Most car batteries are made with a standard lead-acid design, which is composed of positive and negative grids covered with a thin layer of active material. The positive grid is typically created from lead dioxide, while the negative grid is from spongy lead.

There are many batteries available, but all are not created equally. So, choosing the one that suits your car best is important. The best car batteries for hot weather have higher cranking amps and reserve capacity. They also have thicker plates and longer warranties. These batteries come in both flooded and sealed versions and various sizes to fit most cars.

At a Glance:

How Did We Test The Car Batteries For Hot Weather?

To test the car batteries for hot weather, we put them through a series of Tough Mudder-style challenges. Our test included the following:

Performance:

All batteries were tested for their cranking amps (CA) and reserve capacity (RC). The higher the CA, the better the battery will perform in hot weather. The RC measures a battery’s ability to keep power flowing in extreme conditions.

Backup:

Each battery was tested to see how long it took to recharge. We also looked at the battery’s self-discharge rate. This measures how much power the battery loses when not in use.

Capacity:

To check capacity, batteries were tested at various temperatures and climates. We also looked at how much voltage the battery could hold over time.

Results:

After testing all batteries, we found the top 6 batteries for hot weather and put them in a list from top ratings to low based on our own experiences. These batteries performed very well in terms of overall performance, capacity, and backup. Now we’ll go through each battery in detail.
