18V 6.0Ah Battery Replace for All Milwaukee Mk18 Battery 48-11-1850 48-11-1840 48-11-1890 48-11-1815 Mk18 Mk18B Cordless Power Tools Lithium-Ion Battery

I impressed on the power

These i must say good as the original for fraction of the cost, seem to hold charge longer, something I wasn’t expecting. I have 2 original and one of these. Yes they fit and charge using OEM Chargers. LOVE IT

Battery life is no where near stated and is more of a 2.0Ah battery when I compare the life to my OEM Milwaukee batteries. Generic brands are usually not as good as OEM but this one is downright horrible when I compare the output to a OEM 4Ah or even an 2Ah. I should have just gone OEM!

Está funcionando bien espero y aguante la friega de todos los diad

Works great

Lasts long, works great and fits my tools.

While not scientific, something I like to do with these aftermarket batteries is test their runtime on my LED work light in comparison to an OEM battery. It seems like a reasonable test – simply see how long each battery runs, and then do some math to get an idea on the actual battery capacity.I compared the runtime of this “Cukect” 6Ah battery, to that of an OEM Milwaukee XC 5.0Ah battery. The Cukect battery ran for 3 hours and 25 minutes. By comparison, the OEM Milwaukee battery ran for 3 hours and 30 minutes – just slightly nudging out the Cukect. So, from this test, I would conclude that the actual capacity of the Cukect is about 5Ah, not the claimed 6Ah.The external shell of the battery is about on par with other aftermarket batteries I have seen, and it also lacks the OEM rubber overmold on the base of the battery as well. Other aftermarket M18 batteries I have seen also seem to skimp-out on the rubber overmold unfortunately. Thus, the slick plastic base of the battery means that drills, impact drivers and other tools that rest/stand on the battery might slide around when placed on smooth surfaces.The battery functions and fits normally in all my M18 tools, minus one - my 2-gallon vacuum (model 0880-20). The battery will not lock into place when used with the vacuum, although it does still function without issue. I would also add that the battery charges without any issues on my OEM charger. Also, the battery life indicator functions properly, but it can be difficult to see the LEDs depending on the angle you are looking at it.When it comes down to it, this battery is about what you would expect for an aftermarket unit in terms of construction, fit and finish. But, the claimed capacity of the battery is not accurate, and that detracts from the overall value – you are paying for a 6Ah battery, but in reality, appear to be getting a 5 Ah battery. As it stands now at the current price point of about $35, I think there are better alternatives available.

Love it works well
