For now, let’s focus on the voltage as power. I’ll explain those anomalies in a later article. Even with that, the math doesn’t work out perfectly.
#Voltage vsamp full
That 3.6V cell actually produces a little more than 4V at a full charge state. They can produce a higher voltage at a full charge state than low. The voltage varies slightly within the cells based on the amount of charge that they hold. If you’re doing the math along with me, you already know that there’s an issue. Need a 12V battery? String 3 of them together in a series. Each battery is capable of delivering a specific amount of voltage, typically 3.6 volts in the 18650 lithium-ion cells that are used.
If you were to take apart your battery (please don’t do that!) you would find the individual battery cells that store and deliver power to the tool. Voltage vs Amp Hours: Wiring to Increase Voltage Basically, the larger the fuel tank (watt-hours), the higher the energy potential you have – it’s just a matter of how you use it. If you look on the label for most batteries, it will tell you the total watt-hours of its capacity. These two measurements are born of the actual battery capacity-a term known as watt-hours.
Most people boil cordless tool numbers down to the idea that voltage is equivalent to power and amp hours are equivalent to run time.
This is great when there’s a virtually infinite power supply. With corded tools, we often describe the amount of power based on the number of amps that it draws. amp hours is one of the most basic questions asked of cordless tools.
