Joseph★★★★★
Bigger jobs on my M12 tools used to mean swapping batteries constantly, but this 4.0 pack with the charger keeps me running for hours without stopping. The extra runtime is exactly what I needed, and the charger tops them up quickly in between tasks.
Eva★★★★★
The new 4.0 battery lasts me almost twice as long as the old 2.0 on my drill, and the charger tops it off in under an hour. Really nice to have the extra runtime without swapping batteries mid-job.
Chloe J.★★★★★
Been using this kit with my impact driver for remodel work, and the 4.0 battery runs almost twice as long as my old 2.0 packs. The charger is nice and compact too—slips right into my tool bag without taking up much space.
Violet B.★★★★★
This 4.0 battery noticeably outlasts the older ones I was swapping out constantly, and the charger gets a dead pack back to full in well under an hour. It’s a solid upgrade for anyone who needs their tools running longer without the weight penalty.
Hazel★★★★★
Coming from the old 2.0 batteries, the runtime difference on my impact driver is honestly night and day — I finished a whole deck build without swapping packs once. The charger is compact enough to toss in my bag, which is handy for jobsites.

The 4.0 battery noticeably outlasts the 2.0 I had before—I finished a whole deck project without swapping packs once. The charger is compact and gets a dead battery back to full in under an hour.

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.
Chloe H.★★★★★
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.
Steven K.★★★★★
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.
Michael★★★★★
Running my impact driver nonstop on a deck job, this 4.0 battery lasted almost the whole afternoon without needing a swap. Charges noticeably faster than my older packs too.
