So far so good. I bought these to replace some BRAND NEW batts that are Milwaukee but acting up. Shame on you Milwaukee...not even 10 charge cycles and your batts are giving fail codes.

They charged up just fine and are functioning in my Milwaukee vest just perfectly. Only thong is you have to make sure the battery is seated in the vest power unit fully by pushing firmly. Never had to with the Milwaukee brand batteries.

The order was exactly what I ordered and they are good batteries

I bought a set of two of these batteries for my Milwaukee 12V hammer drill/driver (model 3404-20). They never worked properly. The wattage also seemed low from the beginning, and the drill would routinely stop working after 5 minutes or so, then work again after a few minutes of cooling, which is impractical for most applications. After about 10 usages, the batteries stopped working altogether. After considerable troubleshooting finding low voltage (~3-4V rather than 12) and that they would not charge or respond to efforts to "jump-start" them, I removed the red plastic cover to find that the wire connecting the batteries (there are 3 batteries inside each pack) to discharge/recharge mechanism had BURNED off at the base of the batteries, which is why they wouldn't recharge. The inside of the red plastic cover was burned and melted at that joint. This is why the drill only worked intermittently -- it was overheating at this joint, which negatively impacts wattage. One could conclude this was a rare and random manufacturing defect. However, it happened with both batteries I bought from this seller. Therefore, I conclude it is more likely a sign of systematic poor production checks and balances. In any event, this wasted a lot of my time.
