    • Good as the real thing
Size: 2 Count (Pack of 1)
I bought these in April '24 and now its Feb 2026. I use these daily and put them through a full charging cycle almost daily. They still work great. I'm not sure if they are the actual ones from Milwaukee but it doesn't matter at least in my case. These are as good or better than the authentic ones. So if they are fake they are damned good fakes and very much worth what I paid for them. The real ones are for sure a huge rip off. ... show more

    • Excellent price point
Size: 2 Count (Pack of 1)
Just received these batteries and haven't had a chance to use them yet. They are Milwaukee brand and I bought these because of the price point which is a lot cheaper than the stores here in town. They are new and in the original packaging. The battery package was damaged, so that is more than likely why they had a cheaper price point because big stores won't sell a product that the original packaging is damaged. Both batteries are in new condition and unscathed. Both batteries charged right up which tells me they will function properly and take on the work load. ... show more

    • My Milwaukee M18 charger had a problem with these batteries
Size: 2 Count (Pack of 1)
Packaging was poor. The plastic sleeving was cracked because the batteries were rattling around inside the Amazon box. However, there was no visual damage to the batteries themselves. When I purchased my first M18 Fuel drill (over a year ago), it came with a battery and a charger. When this drill was recently stolen, I replaced with a new M18 Fuel drill and bought these two batteries. Both batteries showed only one red bar when they were unpackaged, so they needed charging. The first battery, on insertion, flashed red and green indicating a faulty battery pack. I tried reinserting several times but to no avail. The second battery slow-flashed red, then solid red, but successfully charged the battery. To see if the first battery pack worked at all, I loaded it into my drill. The battery appeared to work fine. I then put the battery into the charger, and, to my surprise, the battery charged up successfully. Again, on completion, the charger light was solid red. I inserted the original battery which showed red during charge and then solid green on completion. So definitely these batteries, although they look identical to the original 5Ahr batteries, somehow differ internally. No idea why. In use the batteries appear fine. I haven't done a rigorous test of battery life, but the seem to perform fine compared to the original battery. If I had to guess, I suspect Milwaukee have made changes to the battery pack and the older charger seems confused by the new version. I will probably go out and buy a couple more batteries from my local store as I'm not sure I trust these ones. In general, MIlwaukee batteries, rather than clones, have a good reputation and deliver true 5AHr endurance. They are expensive, but worth the money. However, having them misbehave during charging was 'unsettling'. ... show more

100% genuine Milwaukee product. Arrived in original manufacturing packaging (which almost always requires a first-aid kit close by). Battery was manufactured 4 months ago, so it’s not some over-stock that’s been aging on a shelf. Will purchase from again!
