M12 and M18 12-Volt/18-Volt Lithium-Ion Multi-Voltage Rapid Battery Charger

A must if you get the XC or HD batteries. I like that it charges both my M12 and M18 batteries.

I brought weed eater that came with high output XC 8.0 battery and M 12 and M18 charger. I don’t know if it’s battery messing up or charger. Battery dies quicker than when I got it. It also charges way to fast.

This charger came with a blower and weed eater combo. I have two other Milwaukee chargers and it charges the same speed as this one.

I bought another after my old on failed. and after 4 days of using the new one. The charger died?!?! what gives, this give me a very different impression of "heavy duty"

For the record all of my handtools are Milwaukee! I purchased the rapid charge back in June 2021 and this thing makes a hissing sound like it’s burning and gets very hot I will include a picture that shows it gets to 117°. I am more than a little disappointed with this product because I have to sit here and wait for it to finish charging due to the fear that it may go on fire.

I bought this product yesterday plugged in today for the first time to charge some batteries first battery in and it’s making a hissing sound almost like a car tire losing air it is super hot and smells like wire burning had to unplug it. Pretty disappointed to be honest since my entire line of power tools and cordless tools or Milwaukee kind of a letdown.

It dose what it says it will do faster charging for your battery

This charger charges insanely fast. Definitely recommend this product. I use the circular saw for deck building at my small business, it well passes the standard I had thought it would have had.

I have to admit that the charge time on this was pretty fast. It seemed to be faster than other brand’s battery and charger systems I have used in the past. It does seem to make a buzzing/humming noise while its charging the battery but this isn’t that noticeable unless you’re right next to the charger.

I'm really glad Milwaukee is finally in the rapid charger business. It seems like the competition has had an edge in this area for a while, and Milwaukee finally stepped up one of the few areas they were lagging in. Just a quick note up front, this is a SEQUENTIAL charger, not a parallel charger, just like the original M12/M18 multi-voltage charger. If you want a parallel charger, take a look at Milwaukee's new Rapid Charge Station, which is essentially three of these chargers that work in parallel. The form factor of the new rapid charger is almost exactly the same as the original M12/M18 multi-voltage charger. That's good news for anyone who wants to replace their original charger in an M18 tool case - the new rapid charger fits just fine. The keyhole mounts on the back are the same size and spacing as the older model, so if you've got one mounted to the wall already, you can just replace it with the rapid charger without changing out any hardware. The new design has a lot more vent area than the old one, and Milwaukee has moved most of them from the bottom up to the sides, which allows for more airflow. I don't think the charger is actively cooled with a fan though. I can hear a faint hum/whir when I hold it up to my ear while a battery is charging, but I can't feel any forced air coming out of the vents. The rapid charger also has a new LED status indicator in addition to all the old ones. Now there's an 80% charge indication in the form of a flashing green light, which lets you know when you can get a substantial amount of work done with and almost charged battery, in case you're waiting on it for completion of a project. There's also the standard solid red for charging, solid green for charged, flashing red for waiting to charge, fast flashing red for waiting to cool, and flashing green/red for a defective battery. Luckily I've never encountered the last two states. As for faster charge times, I'm getting my 1.5 Ah M12 batteries fully charged in about 22 minutes, which is down from approximately 30 minutes. That's 27% faster, which is close to, but not quite at Milwaukee's "up to 40% faster" claim. Although I wasn't watching the batteries like a hawk, so it's possible it hit the 40% faster target of fully charged at 18 minutes. I checked at 14.5 minutes and it was blinking the 80% status, which is actually right on track for fully charged at 18. The 2Ah M18 battery I tested was fully charged in 25 minutes, and the 4Ah M12 battery was 80% charged at 45 minutes, and fully charged after an hour. Once again, I wasn't sitting at the charger unblinking with a stopwatch, so all times may actually be faster than I reported.
