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.

Changing my review due to the customer service. They sent us new batteries due to the ones failing so quickly. Customer service is huge in products in my opinion, so I’m thankful that they are helpful and care about faulty products. Batteries both stopped working within 3 months. Don’t get these if you’re looking for durability and quality. These are cheap knock offs, and we didn’t realize when we bought it that they’d be a waste of money.

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.

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.

These Wurthman 5.0Ah batteries are exactly what I needed. I’ve been using them as replacements for my M18 tools, and they perform just as well as the originals—plenty of power and long-lasting charge. They snap in securely, charge fast, and keep my tools running strong all day. Having two in the pack is a great deal, especially for the price. If you're looking for dependable battery replacements, these are a solid choice. Highly recommend!
