  • The extended battery is GREAT with all my other Milwaukee tools
I purchased my first Milwaukee 12 volt tool around 2012. Since then, I have purchased several more, mostly drills. I LOVE the lighter weight of the tools, and the smaller battery size is the reason. The Milwaukee brand is FABULOUS! I also received a Milwaukee coat at Christmastime, that uses this M12 system. The larger size of the extended capacity battery doesn't seem to affect the balance or stability of the tool during use. The charging speed is generally faster than any other battery tools that I own. This is a DEFINITE rebuy, as my other batteries reach the end of life. ... show more

  • Milwaukee Factory Batteries
I recently purchased the Milwaukee 48-11-2412 Twin Pack of 3.0 Amp Hour batteries, and they have quickly become an essential addition to my tool collection. The compact design, reliable performance, and long-lasting power make them incredibly useful for both everyday DIY projects and more demanding professional tasks. One of the first things I noticed was how lightweight and balanced these batteries feel when attached to Milwaukee tools. Despite their compact size, they deliver impressive runtime and consistent power output, allowing me to work longer without constantly swapping batteries. They charge quickly and maintain strong performance even during heavier applications. Battery life has been excellent for a wide range of tools and projects. The 3.0 amp hour capacity provides a great balance between runtime and portability, making these batteries ideal for drills, impact drivers, and other cordless tools where reduced weight and maneuverability are important. Having the twin pack is especially convenient because one battery can charge while the other is in use. The build quality is outstanding, which is something Milwaukee products are well known for. The batteries feel durable and well-constructed, and they fit securely into tools and chargers without any looseness or issues. They arrived well-packaged and immediately gave the impression of being high-quality equipment built for regular use. Another feature I appreciate is the reliability and compatibility across the Milwaukee M12 system. The batteries consistently deliver dependable performance, and the integrated fuel gauge makes it easy to monitor remaining charge levels during work. Their compact profile also helps reduce fatigue during extended use. After using them regularly, I’ve been very satisfied with their performance, durability, and convenience. They provide dependable power without adding unnecessary bulk, and the twin pack setup makes it easy to keep projects moving efficiently. Overall, the Milwaukee 48-11-2412 Twin Pack of 3.0 Amp Hour batteries is a dependable and well-designed power solution for cordless tools. It offers excellent runtime, durable construction, and practical everyday performance. I would definitely recommend it to anyone looking for reliable replacement or backup batteries for their Milwaukee M12 tools. ... show more

  • Milwaukee batteries
Most of my tools are the 20 volt dewalt, but I inherited a Milwaukee sawzall, so I added a few more Milwaukee tools and I've been happy with it. The battery life seems good the build quality seems good. These batteries work well. I have found over the years the aftermarket batteries do not seem to hold up there as well, there is a reason they are less expensive ... show more

  • ⭐⭐⭐⭐⭐ Genuine Product - Don't Let the Price Scare You
I'll be honest—I hesitated before clicking "buy." The price was noticeably lower than Home Depot's, and with Milwaukee batteries, that's usually a red flag for counterfeits. I almost talked myself out of it. But I took the chance, and I'm glad I did. After putting this M12 through its paces with my drill and impact driver, I can confirm it's the real deal. Charges properly on my Milwaukee charger, the fuel gauge works as expected, and the runtime is consistent with my other genuine Milwaukee batteries. If you're on the fence like I was, don't overthink it. Sometimes, a good deal is just a good deal. ... show more

  • Happy with my new Milwaukee battery
I decided to give this M12 a try and I’m pleased I did. It charges well on my Milwaukee charger and the fuel gauge functions accurately. Using it during work with my drill, I found the runtime to be in line with my other genuine batteries. If you’re unsure about buying, I’d say go for it. Sometimes, trusting the brand makes things easier. ... show more

  • No issues
Batteries are genuine Milwaukee and priced reasonably at time of purchase. Everything works good and as intended, it’s nice having the bigger amp hour for bigger jobs and seems to make the tools more powerful compared to the little batteries.
