Rated 2.0 out of 5.0 by Susquatch New design are much better
First got my tools with 4 of the old style batteries (No "M12" in a white box on cover). One died almost right away. Used the old drain it and recharge trick which worked for a while. I notice others have used this with some success too. Unfortunately all the other batteries died same death within 1 year of modest use. Received a new tool with the new battery style (Says M12 in a white box on cover) have purchased a few more since. All are working fine with no sign of trouble well after a year. DO NOT BUY old style batteries. Milwaukee should stand behind their products and issue a recall !!!!! I'd give zero stars but new style of battery seems to be ok.

Rated 5.0 out of 5.0 by Faisal Longer run time and re-charges fast
I have been using it with M12 drill and Hackzall saw for all sorts of home projects. It certainly gives more run time and re-charges a lot faster but not really sure if it provides some extra speed and torque.

Rated 3.0 out of 5.0 by AI8UT Milwaukee 48-11-2401 12-Volt Li-Ion Battery Failure Fix
1) Value of driver is 4 stars.
2) Value of batteries is 2 stars.
I purchased the driver & after about 2 yrs of occasional use (~100 hrs), both batteries failed to charge within 30 days of one another. I googled '48-11-2401 Reviews' and found one very useful. The owner had the very same problem & was able to fix it without buying new batteries.
He had a kit that included a flashlight. He used the flashlight to drain the battery. He then plugged the battery into the charger & it recharged as normal.
I gave it a try by putting a low battery in the driver & using a twist tie on the trigger to keep it running. After switching itself off, I plugged the battery into the charger and it charged as normal.
I am happy to report the both batteries have taken 2 full charges each since [2+ mos ago] and I have not yet had to shell out $70-$80 for 2 new batteries.
Had the battery recovery not worked, I'd probably trash the Milwaukee driver and returned to my dependable corded drill.

These batteries have surprised me so far. I use the M12 kit for appliance repair because it is light weight and the batteries seem to last forever. I can typically get a week of use out of one battery in my impact driver before I have to charge it. The flashlight uses a bit more power so I usually have to charge it before the end of the week. So far I really like the M12 items from Milwaukee.

Rated 5.0 out of 5.0 by Robert A genuine Milwaukee battery
I purchased this battery from Home Depot because it is a genuine Milwaukee battery and not a clone made entirely in China. I can be confident that this battery will charge without mishap or danger to my health.

Rated 5.0 out of 5.0 by Mike Light weight, LONG LASTING
I have three of these 12 volt batteries, one LED work light, one 3/8 impact tool and one 1/4 impact tool.
The work light is the high consumer so far. The 3/8 impact tool is IMPRESSIVE at how great it works and how little power it uses. Yes its brushless (fuel).
The 1/4 impact tool has proven itself more times in removing LONG screws. It has brushes in the motor, but still does a great job with little power consumption.
The work light is fantastic.
The batteries charge quickly, and will put up with anything I throw at them when using any of the three tools.
Milwaukee has a HOME RUN with these products and of course the batteries.

Rated 5.0 out of 5.0 by dickhaber Should have come with rotary tool!
As the title says this battery should have come with the Milwaukee Portable Rotary tool as the SECOND battery for the tool.

Have had this tool for over two years. Used it periodically, nothing too strenuous or long cycle times. Hadn't used the tool for about 6 months and when I pulled it out to use it yesterday, both batteries were dead. Plugged them into the charger and got the dreaded red and green flashing lights and the batteries would not charge.
Do I go out and buy the flashlight to try the rejuvenating trick, buy new batteries at $40 a pop or just chuck the tool and buy a Bosch screw driver?? The design of the screwdriver is great, light, easy to use but the unsatisfactory battery life doesn't lead me to buy another.
This is the second battery operated Milwaukee tool that I've owned and the 2nd one to have the batteries give out prematurely.
