user happy with the batteries, well worth the price

Great product, works great and price was right

Works as good as the original name brand batteries.

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.

Works really well for what I bought it for ....
