As with many brands’ electric power tools, Craftsman’s V20 system features dozens of tools ranging from drills, impact drivers, and circular saws—and they all support interchangeable batteries. This interchangeability reduces the need for having one battery and charger per tool you own. If one dies, throw it on the charger and grab another battery off of some other tool, then keep working. Batteries are somewhat of a sneakily expensive component of owning electric power tools, and right now, Amazon is offering 55 percent off a two-pack of Craftsman 20V 4.0-amp-hour batteries.
The sale brings the price of this two-pack from $164 to $74, saving you a nice $90. That’s enough to buy this best-selling Craftsman V20 Cordless ½-inch Drill/Driver Kit (which is currently also on sale for 13 percent off). You can choose from a long list of tools in Craftsman’s V20 system that will work with these batteries, giving you plenty of power to tackle unfinished projects.
The runtime of Craftsman’s V20 batteries depends on multiple factors, including each tool’s demand and the efficiency of its motor and electronics. In general, a 20-volt battery with a capacity of 4.0 Ah will last about an hour under continuous use. The good news about Craftsman’s V20 batteries is they have no memory and low discharge. The memory effect—which typically plagues older nickel-cadmium batteries—essentially means a battery must be fully discharged before recharging. You can charge Craftman’s batteries at any point, no matter how much juice they have left. Low discharge refers to the rate at which a battery loses its charge when not in use. The batteries also feature an LED, giving you a quick look at how much energy is left.
Unfortunately, this deal doesn’t come with a charger, so you’ll have to buy that separately. You can find a single-port option for $65 through Amazon or spend a few more dollars for a dual-port model. The batteries you get in this two-pack feature a 60-90 minute charge time, so keep that in mind. Craftsman makes some of our favorite power tools, and ensuring your toolkit is properly equipped to keep them running is worthwhile. For 55 percent off, you’re saving a good chunk of change while making sure you’re prepared to tackle projects that need finishing this summer.
