Use 18v battery on 20v dewalt

As you might know, the difference between Dewalt 20V Max and 18V is essentially marketing in nature, rather than relating to electrical power. There is no functional difference between 20V Max and 18V! More than

Use 18v battery on 20v dewalt

We promise you. Here in the U. A voltmeter is all that it takes to offer some quantifiable data, and a look inside the battery will show you why. Inside your battery pack are the individual battery cells. In an 18V or 20V Max system, they are always set in groups of 5 wired in a series. Each group of 5 is then wired in parallel to increase the number of amp-hours and overall battery capacity in watt-hours. For more on that, check out our feature on Voltage vs Amp Hours. Each one of those battery cells has two voltage ratings — nominal and maximum. The amount of voltage that a battery produces when fully charged is higher than when it begins to discharge, even slightly. Each battery cell has a nominal voltage of 3. This brings up several interesting talking points. First, many European countries are more strict about how a company can advertise. That means 18V high-power tools and From a marketing standpoint, being able to put a higher number on the tool makes it seem more powerful. Putting a nominal voltage on it is a representation of where the battery operates most of the time.

I should add that Dewalt eventually brought the XR — extreme runtime — branding to the USA to describe their premium 20V Max brushless cordless power tools and higher capacity batteries.

This is the heart of the matter: can you simply swap an 18V battery for a 20V in your DeWalt tool? The straightforward answer is no, they are not directly interchangeable. This incompatibility primarily stems from differences in battery technology and design.

There could very well be or have been regulations. Top Contributors this Month View All. Each battery cell has a nominal voltage of 3. The voltage is the same. This is an older thread, you may not receive a response, and could be reviving an old thread. Yes, it should. For example their 12V max 3Ah batteries say 36Wh instead of the true You are right Nate, the older M12s definitely used For any interested: I buy 14v and 18v nicad batteries for Dewalt.. I would not trust any of the ebay or social media adapters, except in an emergency. At the time, Dewalt said there were still 63 million 18V stem-style batteries still in the field, and that they would continue to support the 18V platform for a long time. The Watt hours rating using 20V in lieu of 18V confuses me too, but is at least consistent. Yes, I have a strong feeling that this kind of marketing malarky would be illegal under EU regulation. Inside your battery pack are the individual battery cells.

One question that often comes up is whether or not you can use an 18 volt battery in a 20 volt Dewalt tool.

For some reason, 20V Max vs 18V debate only seems to be an issue among these 5 cell group platforms. I see all the new Dewalts seem to be 20 volt. It is, however, marked 12V, the part number , and 16 wh. I have found there to be far less confusion between 12V Max and I have been bitten by makita battery style changes and abandoning 12v, ridgid abandoning 24v, … time to switch allegiance. For example their 12V max 3Ah batteries say 36Wh instead of the true This tends to be a technical inclusion; I have never seen a cordless power tool brand advertise batteries with respect to watt-hour ratings. We do hands-on reviews of more than tools each year as standalone evaluations. I never liked those tools, the life span of their NiCad batteries was terrible, and they lost power quickly when using them. Log in. The new [12V Max] terminology, which replaces The performance should be identical. Putting a nominal voltage on it is a representation of where the battery operates most of the time. Sorry to say that I perpetuated the European regulation thing in a comment response. Is it a marketing tactic?
