If you have a stationary tool like a table saw, get a corded tool.

My main concern is….




Dang that tool chest in the background is a wreck!

Nope. I charge my batteries with a hamster wheel. Takes 3 days to charge a CP2.0 but it's totally worth it.

I have 2 super charges and charge all my 6, 8s And 12ah batteries on them only for well over a year and half now! I've had zero issues with any of my batteries and I use them heavily daily! I love the super chargers for my big batteries!🔋

I really dont have anything to say . Im bored and scrolling and landed on this page. Good luck with all the battery stuff.

Milwaukee smart battery tech has gotten to a point where the batteries can communicate with the charger and the charger can regulate its charging output to the peak charge rate appropriate to each individual battery plugged into it. It used to be true that high speed chargers would damage batteries not meant for high speed charging, but it just isn't true anymore unless you have a dinosaur of a charger.

The Samsung INR21700-40T 4Ah cells in the 12.0Ah pack has a specified charge rate of 6A per cell (1.5C). The 13.5A supercharger is only a c-rating of 1.125C, which should be just fine and a walk in the park for these cells. The 1.5C charge rate is what is used for the cells rated cycle-life testing (which is 250 FULL discharge cycles). After 250 full discharge cycles the pack capacity will be reduced to 60% of its original capacity and will become a 7.2Ah battery at that point. Most people don’t do FULL discharges and usually top them back up after only a 50-75% discharge, which means the average user will get 350-500 recharges before reaching these levels of degradation.

Charging them to a full 100% charge and storing them for long durations at 100% would cause far more damage and premature degradation, assuming Milwaukee is actually letting them charge to a true 100% (constant voltage cutoff of 100mA per the data sheet).

I agree, I am a year into the super charger and have had 0 issues.

I use the rapid charger but only with my big batteries and only when I just need that quick half charge to finish a project. I try and keep a stock of charged batteries for the next day

I bought the Milwaukee Super Charger for less downtime between charges and haven't had any issues. I agree, I wish they had a dual M18 port Super Charger.

I’ve never had issues with mine with the charging either. How fast and hard you discharge the battery and whether you let it cool off before recharging is more important. I’ve seen those two factors cause damage to my batteries.

We use these for railroad construction all day every day. Each crew has 15 batteries. We use all of them sometimes twice a day. They last a year…

[fullthrottle]

I only use the rapid charger on my batteries but I have had one of my HD12ah batteries that I use on my OPE fail where it won't take a full charge. I think it's not so much about the charging but more about how hot and fast the battery gets discharged.

[johnperra]

I have learned the proper way to charge my batteries as the stand out in a lightning storm with my hand up in the air works every time

[reddbeard]

Alright Clint!
I got the "Rapid Charger" for my 3, 6 & 8ah batteries out on the job site.
Love it!
Although I do not yet own the M18 Table Saw or 12ah battery (soon to be my next purchase) I appreciate the review.
Go Clint!

[ChiliSeedd]

Did people really think Milwaukee didn’t think about how it effects their own battery before selling it🤦🏽

[paedahe]

I think is was Makita that has a battery tester unit that looks like a charger but tells you what’s up inside. How many charges, if it ever cut out at any time, over heats, Ect... I think Mil-walk-I-A needs one of them too.

[nchistorydiggers]

“This battery right 😂 I say that same heeeera all the time too.

[diverbob]

Just got two M18 12AH and charged both on the charger. Just today, I did the second one and when it got to 3 bars, I took it off to check the temperature, etc. It was fairly warm as expected and since I was not in a hurry, I just put it on a standard charger to finish it off. FYI...Both the battery and the charger were similarly warm. I can easily check the 120 VAC load to get the power going in to the charger. The next time I do a 12 ah, I'm going to measure the input power to the charger.

[monroekunz]

I don't run that many battery's down super charger I use quite often had no battery issues. Makita chargers are similar to super charger a friend has had no battery issues with his makita batteries either. I totaly trust Milwaukee to have done excellent job in design of this like they have with every Milwaukee tool I own. I almost own everything they make in cordless & a lot of other Milwaukee tools no regrets on any of them.
