Cruruakku 9.0AH Replace for Milwaukee M12 Battery 12V 2pack 48-11-2490 48-11-2403 48-11-2402 48-11-2412,Compatible with Milwaukee 12v Cordless Power Tools.

I like these extended range batteries. I like that they have a larger base so my hand can grip the drill and impact driver better. I have dropped my driver many times due to the short, straight sided battery. These last much longer than my original Milwaukee batteries, but they are higher amp-hour versions. They fit the tools and charger well. I'm pleased with how well they are working. I would buy these again

These have increased my drill run time dramatically.

I love my Milwaukee 12V drill because it is lightweight, small, powerful and thus easy to use. It came with 1.5 Ah battery that weighs only 171 grams (6 oz); thus is limited to short duration projects, like assembling furniture, but not adequate for building a deck.Thus I jumped on the opportunity to get these 9 Ah M12 batteries, but they are heavy, weighing 3X more at 553 grams (19.5 oz). This definitely changes the feel and balance of my drill; perhaps would not be as noticeable when using heavier or stationary tools such as a grinder, light, radio, or framing nailer.Like OEM M12 batteries, it doesn’t have a State of Charge set of LED’s, but has 150% the capacity of the largest M12 battery that Milwaukee sells. It worked fine with my M12 tools and charger.

These are great for lighting tools and smaller 12v drills I have yet to place these on the stubby but It seems they can handle all my other generic milwalk tools.

I am a Contractor and Business Owner and I have not had the best luck with aftermarket batteries for the M12, M18, Dewalt or Makita platforms and I am generally not a fan of aftermarket batteries. However, these are good and really surprised me. They fit all my tools and chargers and they CHARGE on the chargers with no issues. Tools run faster with these in the tool at a full charge and the runtimes are definitely way better. I wanted these for things like LED lights and my fans so I do not have to swap batteries as often and for that they worked out great with the side bonus of actually running other tooling at a higher rpm than with an OEM battery and for longer than my 6.0Ah batteries last.Due to my experience with tools and these particular batteries I would happily recommend them and I would order them again. These are some of the better aftermarket batteries that I have received. Overall, I am happy with what I have received. Good batteries and a really good value vs. OEM.

For me its all about the fit and finish. I generally don't like going off-market for my Milwaukee items, but figured I'd try these Cruruakku 9.0AH batteries for my M12 tools. These are well finished, and seem to fit my M12 tools as well as the OEM's. The M12 batteries are often a bit finicky at the pressure points to remove, but I had no problem with these.These charged up just fine in my M12 and combo M12/M18 chargers. Their power - well I didn't test the actual amps, but its rated at 9.0aH which is a good 3x my Milwaukee 3.0AH batteries. I do tend to use my M12's hard especially for hammer-drilling through stucco and ridiculous things like that. And yes, I have the M18's, but the M12's are just so much easier to grab. These batteries should make the activity a lot longer between charges. Again, I can't speak to the actual rating, but my minimal use so far suggests at least 2x with room to spare.Given the current price point on these compared to OEM batteries, it's well worth a try if you're in the market for M12 batteries. And who ever has enough charged batteries on hand?.....

The Cruruakku branded 9.0AH batteries (2) fit my Milwaukee M12 tools with no issues. Construction of the battery (hard-plastic) is similar to the Milwaukee, except the Milwaukee has a hard rubber cover. The cover prevents scratching of surfaces, non-slip, and provides some protection for the battery. As a homeowner, not as rough with my tools as professionals, so the cover has not been a deal breaker, as other non-branded batteries have survived well with regular use. The Cruruakku is a higher capacity battery 9.0Ah than my current Milwaukee M12 Red Lithium XC 4.0 (4.0Ah), larger in size, and weighs a bit more (19.44 oz v 14.5 oz). Using a Milwaukee M12 LED work light, the Cruruakku ran for 22 hours vs 9 hours for the Milwaukee before batteries needed recharging. It took about 3.5 hours to fully recharge the battery after it was depleted. For the price of a single Milwaukee XC 4.0Ah battery, the Cruruakku provides two higher capacity batteries, with longer run time and works great with a variety of M12 tools. Durability is unknown as this time for a non-branded battery, as my Milwaukee batteries have worked well over the years. Overall, a good value, rated 5-stars.

Fit my Milwaukee charger with no problem and charged up. The fit in and out of my Milwaukee tools with no problems, the charge last a very good time longer the 4Ah batteries. Much better price than Milwaukee batteries only time will tell if they last as long.
