2 Pack 12V 8.0Ah Replacement Battery Compatible with Milwaukee 8Ah 48-11-2401 Li-Ion Battery 48-11-2420 48-11-2411 48-11-2440 48-11-2402 Tools

These batteries work perfectly with my Milwaukee M12 drill and fits in the Milwaukee battery charger just fine. I've had good use out of these, using them for an 8 hour workday just this past weekend with no problems. And they look good on my tools too. Nothing not to like.

These JAUKIST replacement batteries work well in my Milwaukee® M12 mini circular saw and Hackzall, giving a longer run time and, because of their extra weight, a better balance in hand.They both fit snugly into their respective tools but are a little extra tight when inserted into the stock Milwaukee® charger, although they charge just like originals. Their plastic housing “noses” are 1/2mm wider than the stock Milwaukee® batteries which may account for the tighter fit.Some comparison in-use testing between the stock “Red Lithium High Output” 2.5Ah batteries shows these JAUKIST batteries to have noticeably more capacity, but the 8Ah designation seems a bit optimistic.Comparing their weight to the smaller factory High Output M12 Fuel batteries which are rated at 16 Watt Hours and weigh 176 grams, these JAUKIST wide-base batteries weigh 370g, yet they are labeled 96Wh, which is 6 times the capacity for just over twice the weight.Considering their substantially lower price than even the smallest capacity factory battery, time will tell if these are as much of a bargain as they seem at first. Meanwhile, I will observe their ongoing performance and adjust my review as needed.

I am always worried when I get off brand items but these worked just as well I mean just like the name brand ones my drill came with and I am so happy I got these! There is no difference from the original ones it comes with. They last long, they charge with the charger my drill came with and other then some writing on the Milwaukee ones there is no difference!I would recommend these to anyone in need and these are super well priced for coming in a 2 pack! Now I will never run short of battery power! I love these awesome batteries!

Works in original tool and charger.Will test longevity on multiple tools and report back.So far seems like a good decent replacement for stock m12 batteriesI also wanted to note 8ah is prob a gross exaggeration. I put it next to my 4 ah stock battery

As far as I can tell the battery last, just as long as a Milwaukee battery. It does not fit quite as good as a Milwaukee battery. fits a little loose. Took pictures and compared a Milwaukee battery with this one. So check out the photos.

It makes my M12 tools free standing and yet still lighter than any M18 tool

Slapped it on the charger and it started charging with no problem. The run time is about what I've some to expect from these off brand batteries. It could be better, but overall it's acceptable.
