Sustained Output on Job Sites

Nickel-cadmium chemistry delivers steady current through long drilling or driving sessions without the voltage sag seen in short bursts. The 4000 mAh capacity supports extended run time on tools such as the DC728KA DC930KA and DW984KA during continuous use. Memory effect can appear if the pack is repeatedly recharged before full discharge so occasional deep cycles help maintain capacity.

Simple Swap with Fit Checks

Installation is a direct slide-in replacement for the original DEWALT 14.4 V XRP packs; no tools or soldering are required. The main risk is inserting the pack into an incompatible 12 V or 18 V tool which will not latch or power correctly. Verify the tool model number against the supported list before purchase to avoid a mismatch.
