Rated 4.8 out of 5 by 10 reviewers.
Rated 4 out of 5 by Great performance The performance of the large 4.o batteries in undeniable. Much more power and runtime than the 2.0 redlithium batteries. However, the only problem that I have found is the build qualty. I have noticed that around the glue joints at the seams of the housing are very susceptible to splitting. On mine, after a small tumble the entire black bottom shattered and I had to superglue and tape back together. A larger issue arouse when the tip of the battery neck split which I also had to fix. This is a problem because now the neck of battery is at an angle, which makes it very difficult to place the battery in the charger. March 28, 2014
Rated 5 out of 5 by Really extend running time. I haven't timed it, but these 4.0 batteries really extend the run-time of the M12 tools. Not sure of the science behind it, but they certainly also seem to provide each of my tools with more power. Tools like the multi-tool and the right angle drill have become much more useable. There's also the added benefit of these providing a more stable base for the tool to stand upright. Highly recommended. April 23, 2014
Rated 5 out of 5 Great This is the battery you need if you have the m12 hammer drill and impact set, last twice as long as the other m12 batteries and really isn't much bigger. I also use this battery in my m12 heated jacket and it keeps me warm on high heat for 7 to 8 hrs opposed to the 3hrs I get with the normal batt February 4, 2014
Rated 5 out of 5 by This battery is awesome. I have a Milwaukee multi-tool and this battery really makes this tool work. August 12, 2014
Rated 5 out of 5 by Great addition Does everything I wanted and then gives me a nice rest for my drill if that's what I want or I can switch and use the batteries that came with the drills to get into tight places. August 5, 2014
