    5.0 out of 5 stars Great Milwaukee M12 Alternative
    Reviewed in the United States on December 19, 2024
    I recently purchased a M-12 tool from Milwaukee. My jaw nearly hit the floor when I saw the price of one M12 battery. Thank goodness for amazon, and these batteries. These are comparable with the M-12 lineup of tools, will work in the Milwaukee chargers, and so far have lasted for a long time. I have yet to notice any weakness compared to the factory battery. If you were looking you can notice that it’s after-market… but who cares. The function is great, especially when looking at the price. I have told others about these batteries and everyone loves them. Highly recommend.

    4.0 out of 5 stars Not meant for professional use

    I’m a certified technician so I’m constantly using my wireless drills, impacts and such but after about a month of constant use both battery became defected and unusable. It wouldn’t even power up my Milwaukee m12 stubby 3/8 impact and they would charge but not operate the tool. The battery life was decent and you really can’t beat the cheap price, but you get what you pay for and these are a great example of that. Buy cheap expect to pay for again and again until you buy quality

    They fit my Milwaukee tools and work. They take a charge! Definitely going to buy more of their batteries for other Milwaukee tools and any other brands they may support.

    No concerns.

    I use these with a heated vest for working in the Amazon warehouse and 2 batteries lasted my 10 hour shift. The battery pack drained and shut off but after some time was able to restart and keep warm for an additional 30 minutes at full heat from 1/4 remaining charge. Definitely good enough for the price.

    1.0 out of 5 stars Product does not last

    Bought a two pack back in May 14th of this year. Arrived in time and put each of them to charge. Worked great for a little over a month. Both batteries had the expected power output and fit on the tools perfect. In fact, the fitment was the best part of it. However, one of the battery packs stopped working early in July. I figured it was a defective one so I just accepted my loss and figured if the other one came out good, I would consider it good enough. However, this afternoon (August 5th) the second one stopped working with 3 bars of charge. I check battery life on all my tools before I start using to make sure I don’t drain the battery all the way down. Neither of the two battery packs were ever dropped or got wet. All my tools work flawlessly with my Milwaukee batteries that I’ve had for years. I tried to contact the seller and didn’t even get the chance to because it said the product was not eligible for returns or replacement since June 14th.

    I needed two extra batteries for my Milwaukee heated coat that my youngest daughter bought for me at Christmas time 2 years ago, I now have a constantly charged battery for those long distance truck driving excursions I go on, never have to worry about getting cold!
