DeWalt, a renowned name in the world of power tools, offers both 18V and 20V batteries to cater to the diverse needs of its customers. These batteries are crucial components of cordless power tools, providing the energy required for tasks ranging from drilling and cutting to fastening and more. DeWalt offers two distinct battery systems: the 18V and 20V MAX. While the difference in voltage might seem slight, it can significantly impact the performance and capabilities of your tools. In this article, we’ll explore the distinction between DeWalt’s 18V and 20V batteries, helping you make informed choices when it comes to powering your DeWalt tools.
They Are The Same Batteries
DeWalt’s 20V Max batteries, often labeled as 20V, can be a source of confusion for many. The important thing to understand is that these batteries are essentially the same, they just have different labels. The 18V batteries represent the nominal voltage, which is the voltage at which the battery is discharged under no-load conditions. When a load is applied, such as when a power tool is connected, the voltage drops slightly. This drop is due to the internal resistance of the battery cells.
DeWalt’s 20V MAX batteries, on the other hand, are labeled with the maximum voltage that the battery can reach under certain conditions. This maximum voltage is typically achieved when the battery is fully charged and there is no load applied. However, as soon as a load is applied, the voltage drops to the same level as the 18V battery.
This might raise questions about whether there’s a real difference between 18V and 20V Max batteries.
In essence, the 18V and 20V MAX batteries are physically identical. They have the same number of cells, the same cell chemistry, and the same capacity. The only difference is the labeling.
So, if you’re considering purchasing a DeWalt cordless power tool, you can rest assured that the 18V and 20V MAX batteries are interchangeable. They will provide the same level of performance, and you can use them with any DeWalt tool that is compatible with your chosen battery system.
Why does DeWalt call their batteries 20V?
DeWalt’s decision to label their batteries as 20V MAX is primarily a marketing strategy aimed at conveying a perception of greater power and performance compared to their competitors. By calling it 20V DeWalt suggests that their batteries can deliver a higher voltage than standard 18V batteries, even though the actual voltage difference is non-existent.
This marketing approach is particularly effective in the United States, where consumer protection laws tend to be less stringent compared to other countries. In regions with stricter consumer protection regulations, DeWalt is compelled to label their batteries as 18V, reflecting the true nominal voltage under no-load conditions.
DeWalt’s marketing strategy has been successful in establishing the perception of their batteries as being more powerful, potentially influencing consumer purchasing decisions.
This highlights the importance of understanding the specifications and performance characteristics of power tools and batteries rather than relying solely on the labeling, ensuring that consumers make informed decisions when purchasing DeWalt products.
