A Deep Dive Into the Revolutionary New DEWALT POWERSTACK™ 20V MAX* 5Ah Battery

How DEWALT is powering the next frontier in construction
WIRED Brand Lab | A Deep Dive Into The Revolutionary New DEWALT POWERSTACK™ 20V MAX 5Ah Battery

Batteries make the world go round. They play a crucial role in powering people’s lives, from the remote control to electric vehicles and cell phoness to power tools. Since modern life relies heavily on batteries for normal day-to-day existence, it’s easy to take them for granted, but evolution in battery technology—like solid-state batteries and advances in power-to-weight ratioses—are changing what’s possible. DEWALT, a company that’s been at the forefront of innovative technology since 1924, is bringing revolutionary pouch cell battery technology to its power tools, which has opened up the next frontier of performance and productivity—and changed how the pros work. 

The DEWALT POWERSTACK™ 20V MAX* 5Ah Battery is DEWALT’s most powerful, most efficient, and longest-lasting battery in its class yet.** The DEWALT POWERSTACK™ platform brought to market new technology for the construction industry that allows users to do more with less, and crank through projects during the day with a number of key benefits. 

DEWALT is the first major power tool brand to use pouch cell technology specifically designed for the construction industry. Cylindrical cells make up the familiar rounded-style battery, while lithium-ion pouch cells are flat and stackable. This means that the pouch cells utilize the space that’s otherwise wasted between cylindrical cells, resulting in more stored energy through a more efficient use of the housing. This breakthrough technology uses a stack of five pouch cell batteries, which offers less internal impedance, a longer lifespan, and a superior use of space that’s capable of powering a demanding, cordless job site. 

The DEWALT POWERSTACK™ 20V MAX* 5Ah Battery changes the way we think about power, opening up a new world of possibilities. The most revolutionary aspect of this new battery is that it delivers 50% more power than the DEWALT 5.0Ah cylindrical cell battery, making it the most powerful battery in its class.*** 

Not only does the battery offer 50% more power, but it also delivers 50% more work per charge, which makes it DEWALT’s most efficient battery in its class.† With the inherent efficiency in pouch cell batteries in terms of space and power, construction pros can be productive by getting things done fast. Pouch cells also run cooler in application because of their lower impedance, and due to their increased surface area, heat dissipates better than it does with cylindrical cells. This reduced heat buildup means fewer hot-pack shutdowns and better power delivery—a k a less downtime and more productivity on the job. An LED fuel gauge displays the battery's charge state, helping to avoid unplanned work stoppages. In short, this more efficient and longer-lasting battery helps the pros get more done. 

Another benefit: the DEWALT POWERSTACK™ 20V MAX* 5Ah Battery has twice the lifespan of others in its class, which makes for a better overall investment value.** In general, when batteries are charged and discharged, their useful capacity decreases, which means that over time, there’s less available current to power the tools. The capacity loss in the lithium-ion pouch cells used in DEWALT POWERSTACK™ batteries is smaller than that of a cylindrical cell battery. The increased number of charge cycles is also impressive, because when each battery pack lasts longer, that translates into real savings. Finally, the non-marring, overmolded rubber base helps to protect finished surfaces so pros can do their best work.

And while this battery bests DEWALT’s previous generation of its 5Ah-or-less lithium-ion batteries, it’s still compatible with the full suite of DEWALT 20V MAX* tools and chargers, so there’s no need to buy new tools in order to incorporate this next-generation battery. 

The DEWALT POWERSTACK™ 20V MAX* 5Ah Battery is bringing the construction industry into the next dimension in power. 

* - Maximum initial battery voltage (measured without a workload) is 12 volts. Nominal voltage is 10.8.

** - Class defined as DEWALT XR batteries 5Ah or less, and with respect to:

  •      most powerful - not in application;
  •      most efficient – usable energy, not in application; and
  •      longest lifespan – based on charge cycles.

*** - not in application
