Hey guys! If you're a proud owner of a 2017 Ford Explorer, you know how important it is to keep it running smoothly. And what's one of the most crucial components for that? Yep, you guessed it – the battery! Getting the right battery size is super important to ensure your Explorer starts reliably every time and all those electrical components work without a hitch. So, let’s dive into everything you need to know about picking the perfect battery for your trusty 2017 Ford Explorer.

Understanding the Importance of the Correct Battery Size

When it comes to car batteries, size isn't just about physical dimensions. It's about the battery's capacity and capability to deliver the necessary power to start your engine and run all the electrical systems in your vehicle. Using the wrong battery size can lead to a whole bunch of problems that you definitely want to avoid. Imagine being stranded because your battery doesn't have enough juice to crank the engine – not a fun situation, right?

First off, a battery that's too small might not have enough cold cranking amps (CCA) to start your Explorer, especially in cold weather. CCA is a measure of how well the battery can start an engine in freezing temperatures. Cold weather can significantly reduce a battery's power, so having sufficient CCA is essential. A weak battery can leave you stranded, especially when you need your car the most.

On the flip side, a battery that’s too large can also cause issues. While it might seem like more power is always better, an oversized battery can put a strain on your vehicle's charging system. The alternator is designed to charge a battery of a specific size and capacity. If the battery is too big, the alternator might struggle to keep it fully charged, leading to premature wear and tear on the alternator itself. Plus, an improperly sized battery might not fit securely in the battery tray, causing it to move around and potentially damage other components.

Furthermore, the electrical systems in modern vehicles like the 2017 Ford Explorer are complex and sensitive. Using the wrong battery can lead to electrical issues, such as malfunctioning sensors, flickering lights, and even damage to the vehicle's computer system. These problems can be difficult and expensive to diagnose and repair. That’s why it’s crucial to use the correct battery size and type recommended by Ford.

In addition to performance issues, using the wrong battery can also affect the lifespan of the battery itself. A battery that is constantly stressed due to being undersized or overcharged due to being oversized will likely fail sooner than a properly sized battery. Replacing a battery more frequently than necessary can add up to significant costs over time.

Recommended Battery Size for the 2017 Ford Explorer

Okay, so what's the magic number? For the 2017 Ford Explorer, the recommended battery size is typically Group Size 65. This group size ensures the battery fits correctly in the battery tray and provides the necessary cold cranking amps (CCA) for reliable starting. However, it's always a good idea to double-check your owner's manual or consult with a trusted mechanic to confirm the exact specifications for your specific Explorer model. Ford might have slight variations depending on the engine and trim level.

Group Size 65 batteries are designed to meet the specific power demands of the 2017 Ford Explorer. These batteries typically have a CCA rating of around 750-850, which is sufficient for starting the engine in cold weather conditions. The reserve capacity, which is the amount of time the battery can supply power to the vehicle's electrical systems if the alternator fails, is also an important consideration. Group Size 65 batteries usually have a reserve capacity of around 120-140 minutes.

When you're shopping for a new battery, you'll notice that there are different types available, such as flooded lead-acid batteries, AGM (Absorbent Glass Mat) batteries, and EFB (Enhanced Flooded Battery) batteries. AGM batteries are a popular choice for modern vehicles like the 2017 Ford Explorer because they offer several advantages over traditional flooded batteries. AGM batteries are more resistant to vibration, have a longer lifespan, and provide more consistent power output. They are also sealed, which means they are less likely to leak acid and cause corrosion.

If you're considering upgrading to an AGM battery, make sure it meets the specifications for Group Size 65 and has a CCA rating that is equal to or greater than the original battery. It's also important to check the battery's dimensions to ensure it will fit properly in the battery tray. Some AGM batteries may have slightly different dimensions than flooded batteries, so it's always a good idea to measure the battery tray before making a purchase.

Factors to Consider When Choosing a Battery

Choosing the right battery involves more than just matching the group size. Several factors can influence your decision and ensure you get the best performance and longevity from your new battery.

• Cold Cranking Amps (CCA): As we mentioned earlier, CCA is crucial, especially if you live in a colder climate. The higher the CCA, the better the battery will perform in cold weather. Make sure the battery you choose meets or exceeds the CCA rating recommended for your 2017 Ford Explorer.
• Reserve Capacity (RC): Reserve capacity indicates how long the battery can power the vehicle's electrical systems if the alternator fails. A higher RC is beneficial, especially if you frequently drive in areas with heavy traffic or where you might experience unexpected delays.
• Battery Type: Decide whether you want a traditional flooded lead-acid battery or an AGM battery. AGM batteries are generally more expensive but offer better performance, longer lifespan, and greater resistance to vibration and extreme temperatures.
• Warranty: Check the battery's warranty. A longer warranty period indicates the manufacturer's confidence in the product's quality and durability. Look for batteries with at least a 2-3 year warranty.
• Brand Reputation: Consider the brand reputation of the battery manufacturer. Established brands with a history of producing high-quality batteries are generally a safer bet than lesser-known brands.
• Price: Battery prices can vary widely depending on the type, brand, and features. While it's tempting to go for the cheapest option, investing in a higher-quality battery can save you money in the long run by providing better performance and a longer lifespan.
