With the latest lithium-ion battery technology, 18-volt circular saws today are incredibly flexible and versatile. Li-ion batteries have many advantages over Ni-Cad and NiMH. 18V Li-ion power tools are lighter in weight but pack the power of their corded cousins. The new line of DeWalt 20V Max Tools, while are based off the 18V platform, come with some improvements. The nominal voltage is still 18V. There is no voltage difference between 18v and 20V batteries. But the new slide-on battery design allows for a more ergonomic grip. The 20V line has the electronics in the tool, not in the battery. The DCS391 itself comes with a rubber overmolded comfort grip to deliver optimal balance and control.

The DeWalt DCS391L1 comes with one 20V MAX 3.0 Ah lithium-ion battery. DeWalt claims that the new battery provides up to 57 percent more runtime than leading 18-volt lithium-ion tools. The DeWalt DCS391M1 circular saw kit comes with one 20V MAX XR premium 4.0 Ah Li-Ion battery that provides up to 33% longer run-time than the standard 20V MAX battery packs. It weighs merely 1.42 lbs and features a 3-LED fuel gauge system. Purchased separately, 4.0 Ah DCB204 XR premium 2-pack costs around $100. It charges in about 70 minutes. Of course, if you already own some Dewalt 20V MAX battery packs, buying the DCS391B is perhaps the best route to take.

When it comes to circular saws, the faster the blade spins, the better the cut in terms of control. The motor of this saw has a top RPM of 3700 RPM which is standard for 18 Volt 6-1/2” circ saws. Some top rated models such as the Porter-Cable PC18CSL and the Makita BSS610 are also rated at 3700 RPM. Although it does not deliver the fastest cutting speed in its class, many people have been pleased with its performance. Powered by a 460 MWO motor, the DCS391 has been advertised to be 10 percent more powerful than previous DEWALT 6.5-inch cordless circular saws.
