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.

I just realized that I do have one quite old M12 battery, it is a 1.

One question that often comes up is whether or not you can use an 18 volt battery in a 20 volt Dewalt tool. The short answer is no, you should not use an 18 volt battery in a 20 volt Dewalt tool. The reason for this is that the voltage difference can cause damage to both the battery and the tool itself. On the other hand, using a battery with a higher voltage can overload the tool, causing it to overheat and potentially damage the battery. So, can you use a 20 volt battery in an 18 volt Dewalt tool? The answer to this question is also no. Dewalt tools are designed to operate at a specific voltage, and using a battery with a higher voltage can also cause damage to the tool and the battery.

Yes I realize that generally 18V is old tech, while 20V is newer and lighter and faster charging and longer lasting, but if the Ni-Cad's are in good condition and if you find the proper adapter, I would think they should work just fine. In theory if you created an method of getting the electricity out of the 18v battery you could drive a 20v tool.

This is the heart of the matter: can you simply swap an 18V battery for a 20V in your DeWalt tool?
