Claire★★★★★
Finally got a battery that keeps my radio going through a full workday without swapping, and the charger is faster than the old one I had. The 4.0 Ah pack really makes a difference on my drill too.
Charlotte★★★★★
Was surprised how much lighter this 4.0 pack is compared to my old batteries, yet it keeps my drill running for hours. The charger is compact too, fits right into my tool bag without taking up much space.
Matthew★★★★★
My old batteries would die halfway through the day, but this 4.0 pack easily lasts through my whole trim job and still has juice left. The charger is compact too, fits right in my toolbox without taking up much space.
Emma U.★★★★★
I was pleasantly surprised by how much longer this 4.0 Ah pack lasts compared to the smaller 2.0 Ah batteries I had before—easily got through a full afternoon of drilling without needing a swap.
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.
