New Replacement 6.0Ah Milwaukee M-18 Battery Pack High Output for Milwaukee M18 Batteries Lithium 48-11-1850 48-11-1852 48-11-1862 48-11-1840 48-11-1828 48-11-1822 48-11-1815 Battery Pack

Batteries charged up, fit well, and work fine so far. Haven't put them to a serious test yet so we'll have to see how they hold up.

M18 Millwakee fuel. Works well. The only battery that failed was the original Millwakee.

I needed some more batteries for my drill so I could keep them rotated for a full charge. This is a perfect fit and works great.

Wouldn’t be a problem if their warranty was legit. But they won’t answer a phone or return any of the messages I’ve left on there answering machine. Amazon don’t care and won’t help after 30 day guarantee. They should realize their name is tarnished just like the seller they let sell lies on their site. You’ve been warned. Watch out for these shady sub par batteries!!!

The battery does not fit a standard M18 charger that I have

I've been using this battery in my Milwaukee Floodlight since the day I received it. I only charged it once and it's been going strong since then. The output is nice and is comparable to my OEM batteries. I have not had any issues and will be ordering more in the future as they are a great value.

I got this battery for my Milwaukee 18v cordless tools. Anyone who has cordless power tools knows that you can never have too many batteries. An OEM Milwaukee 18v Lithium-Ion 5.0 Ah battery currently sells for about $70. So, at about $40, this battery costs much less with a slightly higher capacity.My OEM batteries are all 5.0 Ah capacity. However, as you can see from the pictures I took for comparison, this battery at 6.0Ah is almost exactly the same size as my existing OEM batteries.When I received this battery, it had almost a full charge, but I put it on my charger as noted in the instructions before using it the first time. Charging appeared to work fine. Note that some battery makers indicate that 3 to 5 charge/discharge cycles are required for the battery to achieve its full capacity.When I put this battery in my trusty Milwaukee 18v 3/8-inch drive impact, it seemed to have plenty of power. So, two questions that come up are (1) how long before the battery is discharged under a long work session and (2) how long will the battery hold up under long term use. Some of my Milwaukee batteries are several years old so, hopefully, this battery will last just as long. I do not use my tools in a professional environment, but as active do-it-yourselfer, home mechanic, and race car owner, I expect a lot from my tools.

I bought this battery as a backup for my Milwaukee drills and it’s been pretty good I’d say. I don’t believe it’s nearly as good or long lasting as an actual Milwaukee battery but for the money, and for what I do- it’s a solid backup.
