Best Dewalt Chainsaws 2021 Year
Volts and amp hours
For those who might not be clear about what these two figures represent, it’s probably easiest to make a comparison with cars.
Volts: The power demand of the tool, what it needs to function, is the voltage (V). For a 12-volt tool, picture a compact car. For a 120-volt tool (which actually runs two 60-volt batteries in tandem), picture an eight-cylinder sports car. DEWALT chainsaws are rated at 20, 40, or 60 volts.
Amp hours: Amp hours (Ah) are effectively the fuel. The higher the amp hours, the longer a battery will deliver the same level of performance. On a small power drill, you might have a 1.5-amp hour battery. At the other end of the scale, some of DEWALT’s garden tools have 9-amp hour batteries.
Why don’t you just go for the highest amp hours possible? There are several reasons. First, more amp hours equal more cost! A higher amp hour battery also takes longer to charge. Finally, as capacity increases, the tool gets physically bigger, so size and weight become limiting factors.
Voltage and amp hours are not related. You can have a 20-volt, 6-amp hour battery or a 60-volt, 6-amp hour battery. Cordless chainsaws are power-hungry tools, so we recommend the highest amp hours you can afford, with 4 as a minimum.
Manufacturers seldom give run times because they’re impacted by all kinds of things, but DEWALT chainsaws probably run somewhere between 30 and 45 minutes per charge (though some users claim longer). You might welcome the break, but if you want to continue working, you’ll need a spare battery.
