When shopping for power tools, you may have noticed that some brands advertise their products as being 20V, such as Dewalt. However, you may also have noticed that the actual voltage of the battery is 18V. This can be confusing for consumers, so why does Dewalt say 20V?
The Marketing Strategy
First and foremost, it’s important to note that Dewalt’s use of the term 20V is a marketing strategy. By using this term, Dewalt is able to differentiate their products from competitors who use the more common 18V terminology. It also implies that their tools have more power, even though the voltage is actually the same as other 18V tools on the market.
The Battery Chemistry
Another reason for Dewalt’s use of 20V is the type of battery chemistry used in their tools. Dewalt’s batteries use lithium-ion technology, which has a higher energy density than the nickel-cadmium (NiCad) batteries used in older tools. This allows the batteries to deliver more power and run for longer periods of time, even though the voltage is the same as NiCad batteries.
The Nominal Voltage
The voltage of a battery is not a fixed value. It can vary depending on the charge level of the battery and the load it is powering. The nominal voltage is simply the average voltage of the battery during normal operation. Dewalt’s 18V batteries have a nominal voltage of 18 volts, but can have a peak voltage of up to 20 volts when fully charged.
The Bottom Line
So, why does Dewalt say 20V? It’s a marketing strategy that implies more power and sets their products apart from competitors. Additionally, the use of lithium-ion battery technology allows for more power and longer run times, even though the nominal voltage is the same as other 18V tools. Ultimately, the important thing to remember is that the voltage of a battery is not the only factor in determining the power and performance of a tool. It’s important to consider the overall design and construction of the tool, as well as the quality of the battery and its chemistry.

Frequently Asked Questions – Why Does Dewalt Say 20V?
1. What is the difference between 20V and 18V batteries?
Dewalt uses the term “20V Max” instead of “18V” to indicate that their batteries have a higher voltage under load than traditional 18V batteries. This means that the 20V Max battery can deliver more power and run for longer periods of time than an 18V battery.
2. Can I use a 20V Max battery in an 18V tool?
No, you cannot use a 20V Max battery in an 18V tool. The voltage difference between the two batteries means that they are not compatible. Attempting to use a 20V Max battery in an 18V tool could result in serious damage to your tool or battery.
3. Is the 20V Max system better than other cordless tool systems on the market?
The 20V Max system is one of the most popular cordless tool systems on the market, and for good reason. The higher voltage under load, long run time, and compatibility with a wide range of tools make it a reliable and versatile choice for both professionals and DIYers. However, other cordless tool systems may have their own unique advantages depending on your specific needs and preferences.
