Main Features to Consider Before Buying

  • Size – It’s pivotal that you install a battery that’s the proper size with adequate terminal locations. In case the terminals are in the wrong place, the cables on the vehicle might not reach the cell, or they might not fit correctly. Always check your owner’s manual to find precisely what you need. For example, size 24/24F batteries fit many Lexus, Toyota, Honda, Nisan, and Acura vehicles, while size 48H6 batteries fit many U.S. and European cars;
  • Manufacture date – Batteries lose strength during the time, so it’s essential that you choose the newest one possible. They have a code with a letter/number that indicates when batteries were manufactured. Manufacturers use different types of codes, so ensure you know what you’re looking for when you pick a battery. Avoid devices that are older than 6 months from the date they were manufactured.
  • Easy installation – Most batteries are located in the front of your car under the hood. They’re usually easy to access and replace;
  • Reliability – It can be a real hassle if you’re on your way somewhere, and you can’t go because your vehicle won’t start thanks to a dead battery. Top-rated car batteries are designed to be reliable and durable.
  • Technical specs – They’re rated by a variety of elements, including the type, CCA (cold-cracking amps), and reserve capacity. CCA, for example, refers to the number of amps a battery can produce when the temperature drops to 0° F;
  • Weight – Units can weigh between 25 and 60 pounds, which can make them hard to lift and carry. This’s much easier to do if it has a plastic handle. Additionally, you can use the handle to lower the battery into the engine compartment;
  • Warranty – Look for a composition with the longest free-replacement period. Companies typically have a free-replacement and prorated period, which will provide you partial reimbursement.
  • Pricing – You can find a decent auto battery under $100, but not necessarily the best one. The cheaper the product, the shorter its life. Those that are inexpensive may last a year or two. Most cells typically fall between $100 and $300. The lower end will cover lower-performing products, while higher-end batteries will cost a bit more.

Battery Types

Before buying a new auto battery, it’s essential to research which type works best for your vehicle.

Valve Regulated Lead-Acid (VRLA) Batteries

They last longer than flooded models – offered in gel cell and absorbed glass mat (AGM) versions. Both forms are low-maintenance, dry, and sealed to prevent spillage/leaks and recharge relatively quickly.

Flooded (Wet Cell) Lead-Acid Batteries

These batteries are one of the oldest and most reliable models on the market, and they’re offered in serviceable and maintenance-free styles. The serviceable model can be refilled with water when electrolyte levels get low, while the maintenance-free compositions retain its fluids for the battery life.

  • Function – Both forms are filled with an electrolyte that causes the chemical reaction required to provide a flow of an electrical charge;
  • Limited maintenance – These units use freely suspended plates – insulated from each other, sealing the fluid, so you don’t need to top it off.

Gel Cell Batteries

  • Function – They use a gelatin substance in the electrolyte that lowers the amount of discharge;
  • Suitable in warm water – These models work very well in high-heat applications or hot weather. This functionality makes them ideal in heavy-duty or high-performance vehicles that might produce lots of heat under the hood.

AGM Batteries

  • Function – AGM batteries use very thin mats to keep resistance low and generate a high burst of amps. This action makes startup fast and easy, making these compositions perfect for a starter battery;
  • Great in cold weather – The materials in these kinds of car batteries stand up well to low and freezing temperatures;
  • Excellent for vehicles in storage – If you have a vehicle that isn’t driven daily, these cells are suited to hold a charge better than other models when idle.

What is the Best Place to Buy Car Battery?

There are plenty of brick-and-mortar and online stores that sell car batteries, such as Amazon, Walmart, Pep Boys, Advance Auto Parts, and Costco. The main difference between them will come down to battery types, brands, and extra features they provide. However, finding an auto repair shop that specializes in your vehicle’s specific model and make can have additional benefits.

How Long Does a Car Battery Last?

The lifespan of your auto battery depends on how long it can hold its charge and is capable of being recharged. Once it can’t be recharged, it’s the end. There are several things that can affect the battery, including temperature, humidity, and other environmental elements.

It’s critical to remember that no battery lasts forever. Whether you’re keeping your vehicle in storage all year or driving it regularly, you’ll still have to replace the battery at some point. Standardly, an auto cell will last between three and five years. Pushing a battery longer than 5 years, even under ideal driving conditions, could cause it to fail without notice. Therefore, many battery makers recommended a replacement schedule of five years.

How to Disconnect a Car Battery?

If your car doesn’t start because your battery is dead, you’ll want to pull it out and get it checked and replaced. Follow the next steps to see how to change a car battery safely and efficiently:

  • Locate the battery: On most vehicles, the battery is placed under the hood. Other cars may have their batteries in the trunk. Check the vehicle’s manual to find the battery easier.
  • Find positive and negative terminals: The positive terminal carries “+,” while the negative one is marked with a “-.”
  • Get the wrenches: Get the right couple of 10-millimeter open-end wrenches to disconnect the cables and get the job done faster.
  • Disconnect the cables: Ensure the car’s ignition is off and wear adequate eye protection before you start working around the battery. First, unbolt the negative battery cable and be careful not to touch the positive one at the same time. Once you’ve removed the negative cable, push it out of the way and remove the positive cable.
  • Remove the battery: Since most batteries are secured by a clamp, you’ll need to remove the clamp first. Use a socket wrench with an extension on it and remove the clamp slowly.

How to Charge a Car Battery?

First, you need to prepare your battery for charging. To do so, check whether you need to remove it from your car or not. However, the majority of conventional vehicles won’t require any battery removal.

Once you’ve prepared your battery, follow these steps to charge it properly:

  • Turn off all car electronics
  • Remove the negative cable, then positive (be careful not to touch both of them at the same time!)
  • Clean the battery terminals
  • Connect the battery charger (connect the positive cable to the corresponding positive terminal on your battery; repeat the process with the negative cable. Do not reverse these steps!)
  • Once the charging is complete, remove the charger.

How to Test a Car Battery?

You can test a car battery by yourself by performing a simple headlight test.

  • Start the vehicle and turn on the headlights. If everything seems regular, proceed to the next step.
  • Rev the engine. If the headlights stay at the same brightness, it means your electrical system is fine. However, if your headlights dim, it means they’re running off the battery.

Another way to test your car battery involves using a multimeter:

  • Turn off the ignition, lights, radio, and any other accessories in the vehicle.
  • Set your multimeter to 20 DC volts.
  • Put the red lead on the positive battery terminal (marked by a red cover or a + sign)
  • Put the black lead on the negative terminal.
  • Follow the measurement – if the reading is below 12.4 volts, you will need to charge your battery.

How to Clean Battery Terminals?

By cleaning your battery terminals, you’re helping your car battery perform better and last longer. Besides, you’re helping prevent battery corrosion.

To start the process, you’ll need the following material we all have at home:

  • Protective gloves (dish gloves, for example)
  • Baking soda
  • Water
  • Rag
  • Old toothbrush.

Once you’ve gathered the tools, you can begin the cleaning process:

  • Step 1: Mix a tablespoon of baking soda into a cup of water and stir together until it is entirely mixed.
  • Step 2: Turn your engine off. Open your hood and undo the negative and then the positive cable connected to your battery. Then, take a closer look at your battery and check for any buildup, corrosion, or grime on the terminals.
  • Step 3: Dip an old toothbrush in the baking soda cleaner you’ve prepared and scrub the terminals. It might require a bit of elbow grease, but it is critical to clean the terminals thoroughly.
  • Step 4: Fill up a spray bottle with water to spray down the terminals or use a damp rag to wipe the battery.
  • Step 5: Lubricate the terminals with petroleum jelly. The petroleum jelly will prevent corrosion and help strengthen the connection.
