Product Overview


If you have a need to charge a multitude of 18V and 12V batteries at once, then Milwaukee's M18 and M12 Rapid Charge Station is the fastest charging solution in the industry. With the ability to charge 6 packs four times faster, the station charges three batteries simultaneously while charging each pack up to 40 percent faster.
The charger accepts up to three M18 and three M12 battery packs at the same time, reducing the amount of time spent changing out batteries and increasing productivity on the jobsite. It highlights REDLINK Intelligence, which communicates directly with the battery to monitor cell voltage, temperature, and charge status to optimize the performance and ultimately extend the life of the pack. Another highlight of this station is its charge indicator mechanism. When a battery pack reaches 80 percent capacity, the LED indicator will start slowly flashing green. This gives the user confidence knowing they can still complete a substantial amount of work if they do not want to wait for a full charge.
With the growing capacity of cordless tool batteries and the need for faster charging, this rapid charge station is a must-have addition for powering your cordless tools.
  • REDLINK Intelligence for optimum performance and extended life
  • Pass-through plug for outlet space conservation
  • Hang hole guides easily mark mounting points on the surface without measuring
  • Convenient carry handle for jobsite portability
  • Integrated hang holes allow charger to be mounted vertically
  • Accepts up to three M18 and three M12 battery packs simultaneously

Upto 3 batteries at a time
While the marketing details are a bit misleading (hence 4-stars), this is a great rapid charger.

I bought this to charge several M12/18 batteries on high-demand jobsites. I use extensively many cordless Milwaukee tools and need to recharge batteries often. Multiple, single, sequential chargers just don't cut it. So when I read this will charge 3-M18 and 3-M12 batteries at the same time, I was pretty stoked. Well, it turns out it can only charge 3-batteries at the same time. Here's how it works.

There is a bank of three M12 charging ports and a bank of three M18. You can charge all three M12s together simultaneously, or you can do three M18 simultaneously. But you can't charge both banks at the same time. In fact, you can even charge the opposite side at the same time. For example, if you put an M12 in first, the M18 port directly across becomes a sequential only charger. I'm not sure why, but only 3 at a time will charge, and you can't charge the battery directly across at the same time. It can only charge sequentially the port on the opposite side. So whichever M12 or M18 port you start charging first, the port directly opposite flashes until the first battery is fully charged.

As always, no complaints or disappointments. It would be nice to have a unit that would charge 6 of the small standard M12s. I'm an M12 polygamist & enjoy having my pockets stuffed with these little powerhouses as I climb a 3 story ladder without with an extension cord! I have 6 individual chargers mounted on my shop wall & would love to have a 6 charger unit for the field. Milwaukee, "I exercise my Right to bare M12s" with my compact concealed tool carry permit"

Fast. Real FAST
This unit will charge 3 battery's in half the time of the standard kit charger. My 5.0 batteries only take about 50 minutes from dead and 20 to 25 minutes from 2 bars. This thing is fast.

Best addition to the truck this year.
This has been one of my favorite new additions to the truck. When I run larger crews I am now swapping out batteries long before they die, so no one has to stop when they're up on equipment in the middle of something.

Others have noted that it charges only 12v OR 18v at any given time, so I knew that going in. My addition to the unit notes is that it uses a lot more wattage than the single chargers (due to keeping batteries "topped off". I used to run two regular single chargers off a 100w inverter in the truck, but this unit was taking too much power for a 400w inverter so it's not living to it's full potential for me yet.

However, if we have it plugged in at site, and we're swapping out batteries at two bars (50%), there is no more fade or chatter in the tools. When I get home from a 12-14 hour day running a full crew, I don't have to spend a few hours at night swapping batteries in chargers. That was worth the price.

I haven't had problems with durability or size... It could possibly be smaller, but I suspect it needs a lot of venting... it charges loads of batteries, quickly. It fits on the floor between driver and passenger, awaiting a bigger inverter. ;-)

Needs repair
I am a plumbing contractor. I use both 12 & 18 volt Milwaukee tools. Wanted this type of charger a couple years before they decided to build it. I have owned it about 15 months and one bank of the charger has stopped working. It's still under warranty so off to the repair station it goes!

If I install six dead batteries into the to charger, would all six charge simultaneously?
Tool man on Apr 12, 2015
BEST ANSWER: There are 3 ports for M18s along bank #1. There are 3 ports for M12s along bank #2. Any time you're charging a port in the M18 bank, the same port across from it in M12 bank goes on standby (won't charge at same time) and becomes a sequential charger. Bottom-line is you can charge (1) three M18s at the same time, (2) three M12s, (3) two M18s and one M12, (4) two M12s and one M18, (5) one M18, or (6) one M12. So while you can plug in up to 6 batteries, only three will charge and others become standy, sequential chargers.

B1P1(M18) or B2P1(M12)
B1P2(M18) or B2P2(M12)
B1P3(M18) or B2P3(M12)

B=bank, P=port;
Example: charging two M18s (B1P1,B1P3) and one M12 (B2P2): B1P1 is charging. B2P2 is charging. B1P3 is charging. Ports B2P1, B1P2, and B2P3 become standby, sequential chargers (won't start charging until the opposite port is complete).

I'm not sure why Milwaukee had to do this, but what WOULD BE great is charging any and all six at same time vs. just three. Maybe next year?
Has anybody used this product for long enough to notice if it reduces the overall lifetime of batteries compared to the conventional slower and less powerful charger?
Charlie on Dec 24, 2015
BEST ANSWER: I have only owned the unit for about 2 months now and no issues yet.(6 days a week in use) and it is fast. I only have 5.0 batteries (9 of them)(got rid of the rest)and it charges them in 45 to 50 minutes from full discharge.
On another note I am a remote control car nut and in the rc world our understanding of lithium batteries is that charge cycles (when controlled) due not decrease the life of the battery at all. Only over discharging of lithium batteries is what puffs them up and junks them out. My belief is in the beauty of milwaukees system which is completely computer controlled and prevents over discharging and over charging of the batteries, it simply can not happen. I think the reason they did not offer this charger initially is they had not yet thought of it or perfected it.
The big difference is it costs more money and it can draw up to 7 amps of 120 volt ac power when charging 3 M18 batteries from full discharge. Translation to terms most of us can understand is it can use up to the same amount of power as 7 120 watt flood lights which is 840 watts of power. What a lot of guys who charge in there trucks don't realize is to use this at its full capacity in a truck is you need a 1000 watt inverter or it can error out under full load compared to the 250 watts needed by the six pack charger(I also own, awsome "suitcase" for multiple battery's) or other standard chargers.
Hope you get something out of all of this. Good luck and Merry Christmas.

A standard Milwaukee charger outputs 3A @18/12 volts (depending on which battery it is charging.) What is the output per bay of this charger? (A picture of the nameplate would be extremely helpful). Thank you!
Matt on Jan 9, 2016
BEST ANSWER: Max Output Amps are as follows:
4.5 Amps @ 12V
6.0 Amps @ 18V
Can this be wall mounted ?

BEST ANSWER: The M18 and M12 Rapid Charge Station has integrated hang holes to allow the charger to be mounted vertically on a wall.
