5.0 out of 5 stars Best Milwaukee batteries, value and performance
Reviewed in the United States on April 10, 2024
Milwaukee batteries perform better than no-name ones and last longer. These will last years for me because while I use them daily for some task or another, I don't use them steadily all day. Typically, they will last for 2 to 5 days of use between charging. Bottom line is: I know and trust these batteries why would I use something else?
Good quality I like the knurling

I have been using Milwaukee tools and batteries for years. Great tools but the batteries do die eventually, so I like to buy original Milwaukee batteries. These were great just like I expected. Can’t go wrong with OEM Milwaukee!

Batteries came in (as advertised) a double packaging, just like you’d find in any big brand store, charge up and work flawlessly.

4.0 out of 5 stars My Milwaukee M18 charger had a problem with these batteries
Reviewed in the United States on March 21, 2024
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'.

The battery performance is very good last longer than the copied one The only thing I don’t like the delivery person not even try to enter the gate and text me that he don’t have access getting in to the building despite the gates are automatically open and delivered late 8:20PM and the receiving area is already closed
