![]() If the motor can draw more amps, then the tool overall will become more powerful. Power is volts times amps, so if something can draw more amps, then it can be more powerful. Without getting too much into physics, it isn’t just the battery itself. Depends On The Brandįor instance, some brands add stronger motors. Basically, the better drill isn’t necessarily one that is 20 v max it could be the 18 v drill that has better features. The electronics, the motor, and the technological advances of the tool all have an effect. The tool’s output is not just the battery power alone. How can that be if the battery power is the same? It’s because different brands offer various technologies and better designs. They may say their 20 v max cordless drill is more powerful. It’s possible that some people may claim they really can feel a difference. But after researching and learning a bit, you can understand that they are, in fact, the same and shouldn’t be fooled by these marketing tactics. This is the line of thinking that marketers are aiming for. Therefore the 20 v MAX tool must be better than the 18 v tool. People pay attention to numbers, and 20 just sounds more powerful than 18. This is more a marketing ploy than anything else. Tools that are 18 volts are the same as tools that display 20 v MAX.ġ8 V and 20 V Max are the same, but one is the nominal rating, and the other is the maximum rating. The maximum rating is 4 volts for a battery cell. In 18 V and 20 V batteries, the nominal rating for the individual battery cell is 3.6 volts.įor five cells, that is a total of 18 volts. Now, this is where both 18V and 20 V batteries are the same.

The battery cell is made to be used according to the nominal rating. The nominal rating is how much charge the battery can handle consistently. These collections of battery cells increase the watt capacity of the battery.Įach battery cell has two voltage capacity ratings, the nominal rating, and the maximum rating. That arrangement is then wired to another parallel group of five to accumulate more amp hours. They consist of individual battery cells, which are grouped together in clusters of fives. Batteriesīasically, both the 18 V and the 20V batteries are designed very similarly. This can seem a bit puzzling, but when it makes sense, it becomes easier to understand why 18 V and 20 V Max are the same. To entirely understand this battery power business, we need to discuss the details of the battery first. For example, it will say “20 MAX*.” The 18 V will never say max after it. 18V vs 20V Cordless Drillsįirst of all, if you notice carefully, any tool that says 20 V typically says “max” and or has an asterisk after it. They are usually a bit heavier and pricier compared to the 18 V, but many people assume that they are worth the price for the power that they give. ![]() What is a 20 V Cordless Drill?Ģ0 V cordless drills are slowly becoming more and more popular. This is a dependable and staple drill choice. ![]() That means you get the best power for its weight. It has a weight to power ratio that most people prefer. The 18 volt cordless drill is one of the most widely used and popular types of drills.
