20V MAX vs. 18V Batteries: The Ultimate Showdown

20V MAX Vs. 18V Batteries The Ultimate Showdown

When we talk about cordless power tool systems and choosing between 20V MAX and 18V batteries, a lot of people tend to get extremely confused.

Using 18 volt batteries with heavy-duty tools has been a standard for ages. However, 20V MAX batteries are quickly becoming the next big thing.

A lot of power tool users have different queries regarding the dilemma of 20V MAX vs. 18V batteries.

What difference do a few volts make in the long run? How does this difference affect tool performance? What are the benefits and drawbacks of this new battery line for companies?

While the above questions are quite common when it comes to power tool systems and batteries, for most individuals the final decision comes down to a device that seems to deliver more power.

20V MAX certainly sounds like a device that packs quite a lot of power. However, contrary to common belief, 18V batteries are just as powerful.

Here is a detailed comparison of 18V vs. 20V MAX batteries to guide you further and help you make a final informed decision about which one to buy to fulfill your specific needs.

18V vs. 20V MAX Batteries: What Exactly Is the Difference?

In order to understand the mechanics and the design of the two batteries, we started to take them apart.

Once we did so, we realized that both are designed and manufactured in quite a similar way. A wire connects each group of five cells in a parallel arrangement.

This arrangement ensures that the battery delivers a large amount of amp hours and also offers good capacity when it comes to watt hours.

After studying the cells in detail, it was revealed that both the batteries come with different voltage ratings. While one uses a nominal voltage rating, the other uses the maximum one.

The nominal voltage rating of every cell in a 20V or 18V battery is 3.6 volts. When put together, this number translates to nominal 18 volts.

On the other hand, the maximum voltage rating of every cell in a 20V or 18V battery is 4 volts. When put together, this measurement translates to 20 volts maximum.

Therefore, we conclude that the manufacturers of the 20-volt MAX batteries use the maximum rating whereas the manufacturers of the 18-volt batteries use the nominal voltage rating.

18V and 20V MAX batteries thus deliver the same amount of power with the only difference being in the way they are labeled and advertised.

Believe it or not, the power tools that are designed to work with the standard 18V batteries can also work with the 20V MAX ones.

18V vs. 20V Drill: Which One Should You Buy and Why?

Now that you have realized that there is actually no real difference between an 18V and a 20V MAX battery, let’s move to the next section of this article; choosing the right drill.

When it comes to the comparison of 18V vs. 20V drill, there can be significant differences to note.

Here is all you need to know about the differences between various drills that use different types of batteries in order make the right choice:


18v and 20v batteries

When buying a battery, remember that it is highly likely for a drill that uses a 20V MAX battery to be sold at a higher price than one that uses an 18V battery.

Do not spend extra amount of money on a power tool just because only a 20V MAX battery is compatible with it.

Instead, compare rates of multiple high-quality drills on the market and purchase one that suits your budget. With no difference in power, it doesn’t make sense to spend extra on just a more elaborate name.


The usability of a drill contributes greatly to its exceptionality as a power tool.

It is good practice to purchase a power drill that comes with advanced features such as sound notifications and light indicators. These things add to the convenience for the user.

You can also look for a drill that allows you to control torque and speed by offering multiple setting options.

We believe that it is better to pick a drill that uses an 18V battery that comes with multiple beneficial features instead of selecting a 20V drill that doesn’t offer additional features.


When it comes to the torque; regardless of the type of drill you purchase, it is important to consider the product that offers you the maximum torque.

If the 20V MAX drill provides higher torque than the 18V drill, you should go for it and vice versa.

Before you favor one drill over the other, make sure you also keep other specifications and features in mind.

Remember, the higher the torque of a power drill, the better results it will provide especially when being used on hard surfaces.


Before making your final purchase, conduct some researches and carry out comparisons in order to find the best brands in the market.

Find the most trustworthy names and create a list of the top ones. Then sift through the models of drills that they are selling.

Brands such as Dewalt and Makita are among the most reputable and established ones.

Weight and Size

The weight and size of a power drill are also two essential factors to consider before you finally make your purchase. A drill that is extremely heavy in weight might cause a lot of problems in the middle of your drilling project.

Not only it can get exhausting to move the equipment from one location to another but your hands can also get easily tired by holding the tool in one place for too long.

The ideal size of a drill depends upon your personal and professional needs. Decide what you are going to use your power drill for.

For tighter spaces, you might need a drill that is compact and slim. On the other hand, individuals working in a larger space have the feasibility to select whatever size they want.


In the 18V vs. 20V drill dilemma, you know that there isn’t any difference when it comes to delivering power, therefore, it might be best practice to look for other factors that make one drill trump the other.

Accessories such as drill attachments allow you to execute your projects in a shorter time span and enable you to achieve better accuracy.

Therefore, it’s best to select a drill that is compatible to be used in conjunction with various accessories.
