![]() This makes it compatible with existing 18V XR power tools. The DeWalt XR FlexVolt battery is the sole convertible power tool battery in the industry that can switch from 54V to 18V. So, the customer will also require a 20V MAX charger in addition to the adapter. This adapter will allow users of 18V stem top equipment to utilize the newer 20V MAX batteries, which are more powerful.īut the 20V batteries will not charge on the 18V chargers while using this adaptor. DeWalt 18V to 20V Adapter Problems?ĭeWalt has an 18V to 20V Max adapter available. You may get a significant amount of work done on a single battery pack. The battery pack has a short charge time (often less than 2 hours) and a long life (at least 3 hours of continuous use in good conditions). This means that you could meet all of your demands with just two batteries: one in use and one charging while you work. With the XR Line:ĭeWalt 18V batteries are compatible with the whole DeWalt XR line. This started the confusion regarding their 18-volt and 20-volt Maxx batteries.Ĭonsequently, they had two different cordless power tool lines: the 18-volt line, which had already made a name for itself, and the 20-volt Max line, which was intended to be the line’s replacement. However, there are some scenarios in which they can be interchanged, provided that both the 18V and 20V cells are of the same design and style as the other.ĭewalt decided to change the naming of their power tools from the 18-volt Ni-Cad battery to the 20-volt Max lithium-ion battery. report this adīut it is possible to use interchangeable batteries if the batteries are of the same style and design, as well as having equivalent slide-in battery packs.Īlthough, they are not compatible because the 18V cell is designed for a specific product range and is not convertible with the 20V cell. Because you will need to utilize a conversion kit or an adapter to make them work together. ![]() We can say that these batteries are not interchangeable. Are DeWalt 18V Batteries Interchangeable? With the 20V Battery: It’s just a question of whether the firm uses nominal or maximum voltage for its rating. That is the sole distinction between 18V and 20V Max batteries. report this adġ8 volts means 3.6 volts (nominal) × 5 cellsĢ0 volts means 4 volts (maximum) × 5 cells The nominal voltage of each battery cell is 3.6 volts, with a maximum value of just over 4 volts. It is, in fact, a chemical property of the lithium-ion system. When a battery is completely charged, the voltage it produces is higher than when it starts to discharge. There are two voltage ratings on each of those battery cells. ![]() The amp-hours and overall battery capacity in watt-hours are then increased by wiring each group of 5 in parallel. In an 18V/20V Max system, they are always wired in series in groups of five. Individual battery cells are found inside your battery pack. If the tool takes equivalent slide-in battery packs, then 18V can be used in 20V DeWalt tools. Still doesn’t change the fact that the batteries they need are essentially the same. 20V lineup is supposed to have better tools and technologies. This is simply because technology and engineering are developing continuously. However, you may notice some differences between the 20V tools and 18V tools. Which is the compatibility requirement between two different lines of batteries with a certain tool. The voltage in both the 18V and 20V MAX systems is the same. Can I Use An 18V Battery In A 20V Dewalt? The output will be 18V if a load is applied and the battery pack is used. When you measure the output of a 20V Max battery pack just after it comes off the charger, it’ll be about 20V. ![]() What matters is that users are aware that 20V Max battery packs operate at a nominal voltage of 18V. These tools and batteries were not available until a few years after the launch of the 20V Max platform. Dewalt’s current Li-ion power tools are simply referred to as 18V XR.ĭewalt’s more premium brushless tools and higher capacity battery packs in the United States are labeled 20V Max XR. There is no “20V Max” anywhere outside of North America. The 20V Max series was launched with 20V Max branding to “prevent confusion.” The goal, according to DeWalt, was to distinguish the new tools from prior 18V products so that consumers would be aware that they were not backwards compatible. Many individuals believe that 20V Max is more powerful than 18V, this isn’t true essentially. These aren’t 20V battery packs instead, they’re 18V.ĭon’t worry if you didn’t previously know this you’re not alone. Dewalt 20V Max Means 18V in the most basic terms. There’s still a lot of misunderstanding regarding what Dewalt 20V Max entails. 7 Final Words Difference Between DeWalt 18V XR Batteries and DeWalt 20V Max Batteries?
