Dewalt Powerstack™ battery technology

The DEWALT POWERSTACK utilises pouch cells to give you greater productivity than before.

Higher max watts out, so there's a greater range of applications
Faster speed of application, giving you increased output and more jobs done
Improved thermal performance. Pouch cells run cooler in application and dissipate heat better than cylindrical cells
Create less heat resistance which means fewer hot pack shutdowns meaning less downtime and more productivity
Increased cycle life, which means better performance for longer

How does POWERSTACK 5AH deliver more power?

POWERSTACK batteries provide more power by maintaining both higher voltage and higher current under load. Utilising Pouch Cells which have a lower internal resistance, POWERSTACK batteries have been developed to make more power available to whichever tool they are paired with.

How does POWERSTACK 5AH deliver more work?

Pouch cells run cooler in application because of their lower resistance. As a result of their increased surface area, heat also dissipates better than cylindrical cells. Less heat build-up means fewer hot pack shutdowns and less downtime.

How does POWERSTACK 5AH offer more life?

When batteries are charged and discharged, their useful capacity decreases, the cell's internal resistance increases resulting in more heat build-up and less available current to power your tools. The capacity loss in the Li-Ion pouch cells used in POWERSTACK batteries is a small fraction of that of a cylindrical cell.

We’re so confident in the durability of our POWERSTACK batteries, that we are offering our 3 year guarantee for the first time ever on a DEWALT battery. Terms & Conditions apply.
