  • Works just like the name-brand ones
Color: 5000mAh Battery
I was a little unsure about trying a third-party battery, but these surprised me in a good way. They fit my Milwaukee tools perfectly and charge just fine with the regular M18 charger. I’ve been using them for a few weeks now and the battery life has been solid. I’ve used them with my drill and impact driver and didn’t notice any difference from the originals. No weird issues or overheating either. For the price of two of these compared to one Milwaukee brand battery, it’s honestly a no-brainer. Great deal and they get the job done. ... show more

  • so far so good
Color: 3000mAh Battery
So far so good. Non-genuine batteries are always a risk but since they are less than half the price... if one goes bad - no worries. I hope I don't have to follow up on their warranty.

  • Built like an OEM Milwaukee Battery
Color: 5000mAh Battery
I have a lot of Milwaukee M18 power tools. They are expensive, but worth the investment..... However, although they are top quality, the original batteries don't last forever. As I have had a couple batteries go bad over the past month, i started looking for replacements. Seeing the current price of a Milwaukee M18 battery really made me second guess my decision about staying with the Milwaukee brand..... I started looking at some of the M18 "knock-off's", and reading the reviews. During my search I found that there are both good and bad quality aftermarket replacements. The bad ones, made with cheap wiring, have been known to short out and damage tools... What caught my eye on this brand was the picture of the battery internals, showing an "OEM-style" cell frame that is made out of metal, instead of cheap wires that can get pinched and short out. The first thing I did upon receiving the batteries is open them up to take a look. Well, you can rest assured that they are indeed built this way. The welds, circuit board and soldering looks to be very good quality as well.... The main difference that I see between these batteries and the original Milwaukee batteries is that, the plastic housing does not seem to be quite as thick as the original, or as "impact resistant" if dropped. Although I do not plan to drop one, I can't say that it hasn't happened before.... I think a little rubber sealant around the bottom will fix that, though. These are not the cheapest on the market, but all-in-all, i think that they are quality made and a good value. Now, all that's left is put them to work and test them out. I will update if I find any issues. ... show more

  • Charged well and keeps charged
Color: 5000mAh Battery
The battery is 6 amh. It holds its charge very good. It works very good with portable vacuum cleaner. It runs the impact wrench all week with no problem at all.

  • Poor quality and won’t hold a charge
Color: 5000mAh Battery
I purchased these for my Milwaukee drills and within 2 months the batteries barely hold a charge. The battery cells that were used to manufacture these are likely very cheap and poor quality given how fast they started to degrade. Very disappointing.

  • 18 volt batteries for Milwaukee tools!!
Color: 5000mAh Battery
I got these batteries first for the price point and second because they have the very similar power indication lights. They work really well, they last a long time when using, and they seem to be well made. I am extremely happy with these batteries and I hope they last a long time.

  • Best value for two batteries
Color: 5000mAh Battery
This is really perfect battery! I have been looking for it, this is the best price I found out! Works well with my drill, my original god damaged so I was looking for a new one. I do not know how long it lasts, but it powers just like my original one! So I am all set! These are two so I’m set ! I only use it for my house work, so I am satisfied with these! Try it out, best price I found, original Milwaukee battery cost 150+ so I’m good with this. ... show more
