A lot of us love summertime. The sun, beach trips, and warm weather help to create some of our best memories. However, high temperatures can wreak havoc on our vehicles and drain our car’s battery faster than in other conditions. Our buying guide below will help you choose the right battery for your vehicle so it operates properly during hot weather.

Benefits of Car Batteries for Hot Weather

  • Additional engine power. Replacing a car battery ignites the plug much stronger and stabilizes the supply of electricity much better and faster than an old battery.
  • Prevents sudden dead battery. Replacing the car battery eliminates any worry that your car suddenly won’t start due to a dead battery. 

Types of Car Batteries for Hot Weather

Deep Cycle

This type of car battery offers some of the strongest power for small vehicles and can provide sustained power over a longer period of time compared to other battery types. Deep cycle batteries are ideal for small recreational vehicles, golf carts, and marine vehicles.


This is the most common battery used in vehicles on the road today. They’re suitable for a wide range of hybrids and electric cars. Lithium-ion batteries can store a significant amount of energy at a fraction of the weight compared to most lead-acid batteries. However, these types of car batteries feature a shorter battery life, and you’ll typically need to replace your car battery around every three years.

Wet Cell

These are also commonly referred to as “flooded” batteries because they contain liquid. Wet cell batteries are one of the least expensive car batteries for hot weather, which is a huge advantage to most consumers. However, they don’t typically provide a long cycle life compared to other batteries, and some also require regular maintenance to prevent lost electrolytes. 

Top Brands


Optima is a reputable company that launched in 1995 and produces a range of high-quality batteries, including those for cars and home use. A key feature of this brand is its dry cell technology. This technology ensures that the car battery remains long-lasting, even in high temperatures. From this brand, we recommend the Optima Batteries RedTop Starting Battery. This device delivers high power and is extremely resistant to the most common causes of battery failure.


Odyssey creates batteries that can handle many applications and vehicles that have a high-performance demand. Its batteries are ideal for daily use and feature all the power and endurance you need to get you through. We recommend the Odyssey Automotive and LTV Battery. This product offers a three- to 10-year service life. Unlike many other car batteries designed for hot weather, this battery features a non-spillage, mounting flexible design for safety and convenience.

XS Power

XS Power car batteries are affordable and efficient. These high-powered car batteries are long-lasting and feature everything you need for drag racing to boat racing. From its selection of batteries, we recommend the XS Power D3400 12V Battery. It’s compatible with a wide range of vehicles from 12-16V models.

Best Car Batteries for Hot Weather Pricing

  • $20-$50: In this price range, the car battery will be heavy and not as reliable as more expensive devices. The battery will also feature non-corrosion materials.
  • $50-$150: High-performing car batteries in this price range work even in the summer heat, and they’re generally spill-proof.
  • $150 and up: The most expensive car batteries have the highest reserve capacity and feature the highest possible amps, making the device durable and reliable.

Key Features

Ampere Hour (Ah)

This is one of the most important features when it comes to buying a car battery for hot weather. A higher Ah number means the battery can maintain a load for lengthy periods. As a result, the battery will run out less frequently. This additional feature comes at an extra cost, so bear this in mind.


We don’t recommend purchasing a car battery without a warranty to provide you with added peace of mind. Consider checking what’s covered with the warranty, too. Some companies offer a free replacement, while others will happily give you a portion of the money you paid for the product. You should also consider the level of customer service, especially if you’re inexperienced with mechanical tools.

Power Capacity

The battery’s power capacity is usually referred to as CA, or cranking amp. The cranking amp is referred to as the energy that the battery needs to start the vehicle. If you’re looking for a battery to work in hot weather, opt for a car battery with a low CA to ensure it works.

Other Considerations

  • Battery Size. Car batteries are available in a range of lengths, widths, and heights. Check your car owner’s manual or consult a mechanic to make note of the correct dimensions of your car battery. The correct size prevents the battery from becoming damaged due to vibrations.
  • Reserve Capacity. This feature refers to the amount of time the battery can run on its own power without the engine before it stops working. A high reserve capacity prevents your battery from dying due to situations such as accidentally leaving your lights on, a noncompliant engine, and other factors. You should opt for at least 10 hours as a minimum for your own peace of mind.
  • Maintenance. Believe it or not, some car batteries require maintenance, while others are maintenance-free. The maintenance-free car battery is typically sealed and doesn’t require any replacements. Alternatively, a low-maintenance battery is typically unsealed and requires you to occasionally add water. As a result, these are generally the cheapest options, though you need to be vigilant in maintaining them.

This battery is perfect for heavy use, thanks to its leak-proof and high power qualities. It also provides a strong and clean power source with improved safety features for you and the environment.

However, there have been some difficulties with the warranty coverage offered by the manufacturer. Consider this when you make a purchase.

The Optima RedTop Starting Battery is compact yet powerful and heavy-duty. It provides 12 volts of power and is cleverly designed to fit in tight secure spaces. The little battery is capable of providing around 720 cold cranking amps and features dual SAE and GM posts for maximum output and power.

Of course when it comes to batteries, you will want to keep an eye on the amount of reserve capacity they have, too. The Optima RedTop includes about 90 minutes of backup power that can be tapped into. It is also designed to function in all types of weather. No matter if it’s cold, rainy, snowy, or hot outside, the battery is dependable. One of its best features is that it is rated to be 15 times more resistant to vibrations while traveling.

For a smaller battery, it is going to be quite heavy. It weighs around 33 pounds, which can make it much more difficult to lug around and install. The battery is also rather expensive when you compare it to others available on the market.

ACDelco is one of the most reliable and best known makers of vehicle accessories and components. Its ACDelco Advantage AGM Automotive Battery is robust and provides up to 12 volts of power for your vehicle. It’s built to handle large trucks, vans, and SUVs, and works great for small compact cars as well. 

If you’re looking for a battery that is built to withstand bumps and vibrations, then consider this one. It is also built with calcium alloy, which makes it run smoother and extends its life.

While it may not be the most expensive battery on our list, it is up there when it comes to how much you’ll spend. The battery may also be a bit more difficult to install due to its larger and taller size. Watching an installation video on YouTube will help make sure it fits properly and securely.

The Odyssey Automotive and LTV Battery is a great replacement battery for any vehicle. It includes around 330 cold cranking amps. It’s also one of the best batteries when it comes to its lifespan. Odyssey rates its car batteries will last around three to 10 years longer than other brands, or 70 percent longer. That makes a difference if you are traveling, hauling heavy equipment, or running a lot of power in your car.

The Odyssey Automotive and LTV Battery is also set to provide around 400 cycles at 80 percent depth of discharge. Plus, it is built to recharge much more quickly than other conventional deep cycle batteries. Odyssey claims it can be fully charged in around four to six hours. It has a reserve capacity of 52 minutes.

The battery isn’t the most expensive, nor is it exactly cheap. It is mid-priced, but there are batteries that are far pricier. There have also been reports that the battery posts may be on opposite sides when compared to older models. This can really make things confusing when installing the battery in your car.

Perhaps the most powerful battery of the lot, this XS Power Series High Output Battery is incredibly mighty. Set at a premium price range, the XS Power Series has 12 volts of power, 1,000 cold cranking amps, and 65 Ah. It’s an absorbed glass mat battery and built to be spill proof due to its sealed design.

However, as we stated earlier, the battery is heavy, weighing close to 50 pounds. This will make it much more awkward and straining to mount in place, especially if the space you are looking at is tight. You may also need larger bolts or clamps to hold it in place due to its larger size.

The NorthStar AGM Marine Battery is a 12-volt battery that is built to power just about anything you have in mind. It is designed as a quick-start battery that cycles more than 900 times to 50 percent depth of discharge.

It doesn’t matter if you live in a warmer climate or colder climate—the battery will run smoothly and effectively each time.

However, like our previously mentioned battery, this one is incredibly heavy. It actually weighs around 72 pounds, which will make it more awkward to install or mount properly by yourself. Another issue is found in its price. Due to its immense power and size, it is going to set you back quite a bit.
