2-Pack 6.0Ah Milwaukee M18 18V Compatible Replacement Batteries

Dennis Jackson: These after market batteries are the worst thing I have ever purchased from Amazon. The other problem is that they say they are not returnable. One will not take a charge and the other one is defective, garbage garbage garbage. No more buying batteries from Amazon or their partners. This is the second set I purchased as a gift for my son and again they are garbage.

SBW: -Updated review
Seller noticed my negative review and reached out to me right away!
He sent me a replacement battery fast delivery and it works perfect.
Now I have 2 batteries that work perfect. Using in an impact wrench
and they both are well up to the task.
Excellent customer service from this seller.
Very happy!

-Original review.
Purchased 36 days ago and only used a few times.
One of the batteries failed yesterday.
Started with a full charge and only ran for about 5 minutes in a milwaukee impact wrench and went totally dead. Has been on my charger for 3 days and will not get past 1/2 charge. Too late by 5 days to return.
I don't know if the other battery will be any better.
Very expensive for only a few uses.

HStamper: I was hoping these batteries would be a good alternative to the exorbitantly expensive Milwaukee branded batteries. Alas, they worked fine for a short while, but within 3 months of use here's what I encountered. The casing for one of the batteries for no reason separated into two pieces and I couldn't easily fit it back together and glue it so I had to toss it. The remaining battery only holds a charge half as long as my Milwaukee batteries. Both batteries didn't fit into my tools as easily as the original Milwaukee batteries. They get stuck and are hard to remove from the tools and the charger. The search continues...

Update: 8/17/21
Customer service contacted me after I posted my review. They were extremely helpful after I sent them more information about the battery that came apart. Without questions, they sent out two replacement batteries giving me a do over. Impressive responsiveness. I have not used the replacement batteries yet and hope that my original experience was an anomaly. Regardless, they take care of their customers. I upgraded my review to 4 stars since they will go the extra mile to resolve any problems with their product.

Breez Breez : I have only had these batteries for a few months, but I have to say I am INCREDIBLY impressed with them to be a 3rd party battery for my Milwaukee fuel series blower / weed eater. My neighbour had the Milwaukee blower 1st and I borrowed it 2 or 3 times a month, so he proposed that I buy a blower and some batteries and he would give me the charger as well as a Milwaukee fuel weedeater. I was concerned that these 3rd party batteries would not have the longevity or the power that his had but let me tell you, these batteries are nothing short of AMAZING! They charge FAST in the original Milwaukee charger. They're every bit as good as my neighbor's (maybe BETTER, but it's not an apples to apples comparison, mine are brand new and his are a few years old) I can't speak about longevity, but so far so good! Couldn't be happier with my purchase... Don't hesitate to purchase these

Chad Franklin: Batteries do not hold a charge. I charged them both fully a few days after receiving them and put one in my Milwaukee drill and the other in my Milwaukee impact driver. In the 3 to 4 weeks I've had them I have drilled maybe 15 to 20 holes in plywood and pine (all less than ¼") and the drill battery died. So I stuck it back on the charger and checked the life on the impact driver (which I haven't used at all) and it has 1 bar of charge left. These are definitely cheap, but unfortunately that's all they have going for them. Guess I'll have to shell out the $$$ for the genuine Milwaukee batteries. After reading plenty of good reviews I figured these would be a safe buy, but that was certainly not the case for me.

Matthew MeyerMatthew Meyer: I've got to say, I'm impressed. When I got my first Real post-apprenticeship tool kit, an M18 Fuel impact driver and hammer drill, the kit came with nearly the best tool batteries commercially available at the time, 5.0 XCs. Now about 7 years later, I found these aftermarket 6.0 XC/HO batteries in a pack of two, for less than one 5.0 cost back in the day.

The chemistry in Li-ion cells has advanced phenomenally. These 6.0s are no bigger or heavier than my old 5.0s, but they have significantly more available power. I always thought my 7-1/4" battery saw sounded a little rough and wimpy when winding up, but these 6.0 batteries make it sound noticeably smoother, faster, and generally 'happier' to do hard work. My old impact driver and hammer drill also audibly and tangibly perked up with the extra amperage, to the point that I now feel I can put off buying a replacement set for a year or two more. My tools have seen more than their fair share of abuse, but they feel almost new again, with these batteries driving them.

My only regret is that I didn't buy upgraded batteries sooner. I will definitely invest in the even larger size M18s and M12 aftermarket...
