Questions & Answers

Q:I have the older M18 single slot Supercharger (48-59-1811). What are the charge times for the Forge battery with that charger?

Answer This Question

A:  Hello! All M18™ Batteries are compatible with M18™ tools & chargers. For the FORGE battery, to achieve 15 Minute to 80% charge claim, use the 48-59-1815 M18™ Dual Bay Simultaneous Super Charger. - Milwaukee Tool Social Team

    A:  6.0 Forge will charge at the same rate as the newer dual bay supercharger. The 8.0 and 12.0 Forge will NOT as they use cool cycle to achieve their quick charge times that is not on the older single bay supercharger.

        Q:Description says this battery is as powerful as the 12ah. Does it also last as long? If so why is the 12ah being sold ?

        Answer This Question

        A:  The M18™ REDLITHIUM™ FORGE™ XC6.0 does not have the same runtime as the M18™ HIGH-OUTPUT™ HD12.0. However, the XC6.0 does deliver the same amount of power in a smaller and lighter design, allowing users to complete tougher applications faster and more efficiently with an ergonomic benefit. - Milwaukee tool, Social Team

          Milwaukee M18 18V Lithium-Ion REDLITHIUM FORGE 6.0 Ah Battery is a winner
          Milwaukee's M18 18V Lithium-Ion REDLITHIUM FORGE 6.0 Ah Battery is a good choice for the M18 series of tools that Milwaukee produces. This battery, is a high output battery. Within 15 minutes, the battery is "supercharged" to 80%. Milwaukee says this battery has the most power, is the fastest charging, and has the longest life vs their "Red Lithium". Milwaukee touts that the profile of this battery is far less that the 12.0 power battery. Charging was no problem on my Milwaukee dual M12/M18 charger. I let it sit for about three hours and when I checked, the green "charged" indicator was lit. Milwaukee changed the battery strength indicator button, which is now a soft push cover. The LED lights extend across the face horizonally positioned. I like the hard button sytle better. Overall, very happy with the battery. It's not heavy at all. I recommend it. A+ 5*s. Thank you Milwaukee for allowing me to try your product. Thank you Home Depot Seeds for offering this item to me.

          Only Getting Better
          My favorite Milwaukee Battery is my M18 High Output 12.0. When I heard Milwaukee had come out with the M18 Forge XC6.0, I could hardly wait to get one. Delivering the same power, with a much smaller size, lighter weight (2.07 vs 3.42 Pounds), and longest battery life … this is awesome! Mine arrived with one bar (see pic) and took 52 minutes to fully charge on my Rapid Charger. I have used it numerous times with my Weedwhacker, Polesaw and Leaf Blower. No complaints. Milwaukee claims, a big benefit is the fast charge time, but not having their Super Charger, I can not attest to that. If I get the Super Charger, and it does what they claim, I will revise my review to 5 Star. Home Depot sells a bundle, with the Forge XC6.0 and the Super Charger (325545450), at a significant discount. I would suggest getting that, if you do not have either. Made in China.

          Great battery, ignore the complaints vs 12ah
          This battery is amazing in that it offers big power in a small package vs the previous 6ah. This battery was not meant to have run time that matches the 12ah so those making complaints about that need to read more clearly. Thing charges full in less than 30min keeping you in rotation on the job site more efficiently. “Longest life” refers to the cells lifespan, Not the time it holds its charge. I will eventually swap out all 6ah HO for forge batts. Thanks for providing a smaller version of a 6ah

            Good upgrade from the 5.0Ah battery pack
            I got this M18 18V 6.0Ah battery pack to use with my M18 hammer drill, hex impact driver, and multitool. The XC6.0 is a bit larger and heavier than the 5.0Ah battery packs (XC5.0’s) I’ve been using, which doesn’t really affect my use of the tools but it does prevent me from storing the 6.0Ah pack in the hammer drill case. It takes about 40 minutes to charge the pack from one LED (17.7V) to four LEDs (20.6V) on the “fuel gauge” using my 6.0A output rapid charger. I’m impressed with the clarity of the LEDs on the fuel gauge; I really can determine the charge state in direct sunlight. The XC6.0 powers my tools for a very long time. Battery pack was made in China.

            I picked up a couple of these M18 FORGE batteries and the new M18 Dual-Bay Simultaneous Super Charger recently and I am impressed. Fresh out of the box, it took about 20 minutes to get a solid green light from each battery slot. Just that part alone is amazing. Threw them on the backpack vacuum instead of the HIGH OUTPUT 12.0 it normally carries. I couldn't detect any drop in performance for a tool I use every day. Now, it didn't last as long as the 12.0 would have but it was on and off the charger in another 20 minutes. I tried the same thing on the M18 dual-battery blower and pretty much got the same results. Same or better power as the XC8.0 batteries that I normally have on there, just a little less runtime. But here again - the best part is the recharge time. Another ~20 minutes and BOTH batteries are ready to go at 100%. The body size is very similar to the XC 5.0 allowing it to fit a little better in the tool boxes and tools that have tight compartments for the battery (lights, vacuums, etc). They also are easier to remove from the tool, not getting caught up on the slide rails. Overall, the appearance looks a little meaner / tougher than previous XC and HO batteries. I doubt I'll have a reason to buy anymore of the non-FORGE batteries.

            Great to be able to get more done in less time! Game Changer!
            I was very excited when the Milwaukee M18 Redlithium Forge 6.0AH batteries were made available to the public - I mean, who doesn't want longer run times? The claims are indeed true! In my personal experience, this new technology allowed my Milwaukee 1" SDS plus D-handle rotary hammer, and my Milwaukee circular saw, to run longer. I also used this Forge 6.0AH battery on my M18 quik-lok string trimmer, as well as the Milwaukee rubber broom attachment, and those tools lasted longer as well. I ran the battery down to nothing, charged it up using the dual bay simultaneous super charger, and the battery was back to full charge after only 20-minutes. I like the on-board fuel gauge indicator, so I don't have to guess how much battery life is left. The fact that this Redlithium Forge 6.0AH battery carries the same capacity as the HO 12.0, in such a compact size, is mind-blowing! The decreased battery pack weight of using this Forge 6.0, versus the HO12.0, means decreased arm fatigue when used for long periods of time. I really like how the "footprint" of this battery is the same, so that I can use it in all my existing Milwaukee tools. Now I can get more done with fewer charging cycles!

            Does not last along as m18 12.0
            I purchased this M18 xc6.0 FORGE battery yesterday. I let it completely charge for first charge. Which brought it to 21.6v. I timed it in my Milwaukee light to see how long it would last. It lasted 1hr 53min. I did the same to my 4-year-old High Output M18 HD12.0 which only charged to 20.1v. Because it probably been recharged quite a few hundred times and is very used. That lasted 2hr 23min. I expected more from their new battery. So just spend the little extra and get the 12.0

              As Advertised. Makes the high demand tools run better! Can't wait to see this technology in a 12 or 15aH version. Great job Milwaukee!
