The charger clicks in securely and charges noticeably faster than my old one, which is a real time-saver on job sites. Got this kit for the 4.0 battery and it definitely gives my impact driver a solid boost without adding too much weight.

Picked this up to keep my drill running through a full day of cabinet assembly, and the 4.0 Ah definitely delivers twice the runtime of my old 2.0 packs. It charges noticeably faster too—about 40 minutes from dead to full.

These batteries charge noticeably faster than my old ones, and my drill hasn't slowed down even after a full day of driving screws into studs. The charger is compact too, which frees up space on my workbench.

I’ve been running this battery on my impact driver for a full day of cabinet assembly, and it still had juice left—definitely delivers on that extra runtime. The charger snaps the pack in securely and tops it off quick, which saved me from buying a backup.

The 4.0 Ah battery easily got me through a full day of trimming without needing a swap, which is a massive upgrade from my old ones. The charger also topped it off in about an hour, so I never had to wait long to get back to work.
