This is in the technical sense.īut 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. The nominal voltage of each battery cell is 3.6 volts, with a maximum value of just over 4 volts.ġ8 volts means 3.6 volts (nominal) × 5 cellsĢ0 volts means 4 volts (maximum) × 5 cells 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. I've warrantied DeWalt and Milwaukee tools and am more than happy with their service.7 Final Words Difference Between DeWalt 18V XR Batteries and DeWalt 20V Max Batteries? Without the receipt, the manufacturer can only base the warranty off the date of manufacture. Receipts are good to keep on hand, especially if older tools or batteries are purchased new (think a 2018 kit that's been sitting on a shelf). Like most manufacturers, DeWalt's warranty information is easy to understand, and I'm sorry if fishera9 is misinformed or simply had a bad experience. before I found that it was corroded, I submitted a warranty claim with the manufacture code to DeWalt and they sent a new battery immediately. The battery was the one I mentioned above. Sure enough, I got a new charger a few days later. I called a service center for the charger, which requested that I send it to them but told me that DeWalt would replace the charger instead of having them repair it. True, I've gotten no questions asked replacements for both a DCB102 dual-port charger and a DCB204 4Ah battery. ![]() Ive sent a few in to a factory service center over the years without a receipt just using the date code on the battery and they send out new ones. I've also heard of people just calling Dewalt and they just send out new batteries. I'm not familiar with the charger warranty but it must be at least a 1 year warranty. Dewalt batteries should have a 3 year warranty from either a receipt or the build date on the battery.
