What is the difference between 18v and 20V battery?
The short answer is, there isn't much difference between an 18v and 20v battery. They are both made up of 5 power cells that each give 3.6 volts. These power cells have a maximum voltage of 4 volts. So, the 18v figure is calculated by multiplying the 3.6 value by 5, while the 20v figure uses the maximum 4 volt value.
What is the difference between 18v and 20V power cells?
They are both made up of 5 power cells that each give 3.6 volts. These power cells have a maximum voltage of 4 volts. So, the 18v figure is calculated by multiplying the 3.6 value by 5, while the 20v figure uses the maximum 4 volt value. But in real terms, they offer a very similar amount of power.
Should I use an 18v battery on a 20v tool?
The same advice applies to using an 18v battery on a 20v tool. Even though it is less likely to cause damage, it's not great for your tools and you may not get the same performance either. If the manufacturer advises that the batteries are interchangeable, that's fine. Otherwise, use the correct battery or look into options like adapters.
How do 18V & 20V Max batteries work?
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 information, check out our feature on Voltage vs Amp Hours. Each battery cell has two voltage ratings—nominal and maximum.
Which batteries run on 18V volts?
Here in the U.S., manufacturers such as Bosch, Milwaukee, Ridgid, Ryobi, and Makita are all running on an 18V battery platform. DeWalt, Craftsman, and Porter-Cable run on 20V Max systems. A voltmeter is all that it takes to offer some quantifiable data, and a look inside the battery will show you why.
Do tools have interchangeable batteries?
