6.0Ah 18V Replacement for Milwaukee M -18 Battery 48-11-1850 48-11-1860 48-11-1880 Compatible with Milwaukee 18 Volt Cordless Power Tools & Chargers 4 Pack

I own a lot of Milwaukee tools and these aftermarket batteries weren’t really on my radar but I thought I’d give them a shot. Very pleased and will buy again as quality, performance and saving was impressive.

My first test consisted of pulling the trigger of an impact driver while simultaneously snapping one pack onto it. This was done for a fast check. The installation was secure, and there was no wobbling, which was a comforting beginning since working with precision can be nerve-wracking when the battery is loose. I put the remaining three on the normal Milwaukee quick charger and watched as they cycled to a full icon in almost the same amount of time that it takes to prepare a cup of coffee. That time was important; as the actual job started, I required a rotation plan that was really strict. A 3.0 Ah pack is often drained by the circular saw before lunchtime when it is being used for deck demolition. To ensure that the blade never stopped, even while ripping wet five-quarter boards, the 6.0 Ah version was switched out for the standard version. I had completed ninety-four cuts on a single battery, and by the time lunch came, I had not yet triggered the low-power light. The driver performed the feat many times during the afternoon: he was able to effortlessly drive 280 deck-screw drives into pressure-treated joists with only one battery charge. It was a smooth cycle that kept momentum high and irritation low. Each time I slapped a new pack on the tool, the retired one went back to the charger; by the time I swapped it a second time, it was ready again. On the next weekend, I moved my focus to finishing work, which included polishing rail tops and cutting balusters using a miter saw. A smooth speed was maintained by motors that would ordinarily slow down when faced with resistance, which suggests that the battery provides a consistent amperage rather than sinking midway through the curve's progression. While beveling corroded hardware, even the angle grinder, which is known for discharging its juice in a short amount of time, operated for fifteen minutes in a row. As a result of the hands being steady and the engine sound remaining constant, the cuts were cleaner and there were fewer touch-ups required.

These batteries work great with all my M-18 tools. I’ve had them for a little over a month, and I used them for diy projects. They power my drill, impact driver, work light and vacuum, just like the originals.They charge fast on my regular M-18 charger, and the fit is snug with no wiggle. I like that they come in a 4-pack which is perfect for rotating during bigger jobs. I’ve had no issues with overheating or loss of power. For the price, this set is a solid deal and a great backup or replacement option. Definitely recommend if you use your tools often.

These seem like good value for budget tool batteries. I took them apart and the build quality is good. I tried to research the cells but could not fine any real info. They work in the tools I have and they recharge as well. I have not had any problems and I find the power to be good but maybe not 6.0 Ah.

As a contractor who relies heavily on Milwaukee 18V tools, I was skeptical about third-party batteries—but these exceeded my expectations. I’ve been using this 4-pack of 6.0Ah batteries for a few weeks now, and the 30% longer runtime is no joke. I can get through a full workday without swapping batteries constantly, which is a huge win on busy job sites.They fit perfectly in all my tools—drills, impact drivers, saws—just not the chainsaw (as noted).The power delivery is strong and consistent, and I haven’t noticed any drop in performance compared to OEM batteries. Plus, the LED indicators are super handy for checking charge levels at a glance.What really impressed me is the built-in safety system. I’ve had issues with overheating in the past, but these stay cool even under heavy use. And getting four batteries for less than the price of one original? That’s unbeatable.

Why did you pick this product vs others?:I wanted a budget-friendly option that still had solid reviews, and getting four 6.0Ah batteries for this price felt like a no-brainer compared to shelling out for Milwaukee-branded ones.Functionality:These batteries power all my tools just fine—no weird hiccups or compatibility issues. They’ve handled drilling, grinding, and even running my reciprocating saw without breaking a sweat.Fit:They lock in tightly and feel secure in both my tools and the charger. No forcing or wiggle, which is always a concern with third-party packs.Value for money:Four for the price of one OEM battery? That’s serious value, especially when they actually work like they’re supposed to.Durability:I’ve dropped one already (oops) and it didn’t crack or glitch out. They feel solid and well-built, not cheap or hollow like some off-brands.Charging ability:Charging has been fast and consistent. The built-in LED level meter is a nice touch—I always know where each one stands before grabbing it.

I use my West Mountain Radio Computerized Battery Analyzer to test all my power tool batteries. You can see on my attached test results these are 3AH batteries with 6AH labels on them. They charge and work fine, but if you need 6AH batteries, these are not the batteries for you.

This four-pack of 6Ah 18V replacement batteries has been a fantastic value. I’ve used them daily with my Milwaukee M18 tools and they perform just as well as the name-brand versions. The runtime is strong, they charge up quickly, and they haven’t overheated or cut out under load. Fitment is perfect—no forcing or loose connections. I appreciate how solid they feel in hand, and they’ve held up great through tough jobsite use. At this price, getting four batteries that work this well is hard to beat. Reliable, affordable, and highly recommended.
