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.

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.

These 18V batteries hold a strong charge and work seamlessly with Milwaukee tools. Great value for backup power and long-lasting performance.

Using for milwaukee leaf blower. Does the job; only holds a charge for 15-20 minutes so glad we ordered the twin battery pack. Satisfied as 1/2 price of milwaukee branded battery.

Battery life is a dismal disappointment on this purchase. Bought on 6/6/2025. This day, 7/24/25, I placed it on the charger and the charge light is already blinking on one of the batteries in less than 2 months of minimal usage. I last purchased these same batteries on 7/28/23 , only needing to replace 1 this year. The other is still charging. I believe I received a lemon of a battery on this order. And , of course, I am outside of my return window. I’m not sure now that I will trust myself to buy the same batteries. My confidence, approval and recommendation has been shaken. Purchase with caution.

Tested around 3.6ah for both, which is about average for knockoff m18's claiming 5ah. I didn't get them at a very good price though, so they're not keepers to me. Work out your own value based on legit amp hours.
