I'm a die hard Milwaukee fan. You just can't beat the dependability and performance. The wifi connection is great. Program needed settings from your phone and locate tool when it goes missing.

I chose this product based on various reviews found online.  I have used it on a limited basis thus far.  It has performed as advertised.  My previous experience with cordless drill/drivers is that the batteries are the weak link.  I found that batteries could no longer be found for the product I previously owned.  Time will tell if this situation is improved with the Milwaukee drill/driver.

Laptop batteries a strange thing.  For example, replacing them with factory ones can sometimes cost more than the resale of the laptop.  I picked up an X200s for $50 at auction and used some parts around the house to bring it back to life, however the battery attached to it was vintage 2009 and was not charging anymore.  Having had success with Anker's MacBook Pro battery replacement for my wife's C2D MBP, I went ahead and ordered the Anker brand for this one.

On the positive side, this battery works great.  Charges as expected, no problems at all with Lenovo Power Manager, and battery has lasted as expected with moderate work - about 4.5 hours.  While the SL9600 processor sips energy compared to the i5 in the X201, the low-nit screen means you're spending most of your time at 66% brightness.  But, it easily lasts a field trip to Starbucks and a few hours being idle on a desktop.

There are a few negatives.  One that is kind of out of the seller's control is the age of the battery.  While the MBP Anker battery was only two months old, this one was over 6 months old as reported by LPM.  The MBP battery came in at 105% of rated capacity (great!) while this one already was at 97% with 0 cycles.  The locking mechanism is not secure and I once or twice bumped the battery out of the slot if I wasn't careful.  It also slides in and out with more resistance than the factory battery would.

An inconsequential minus is that the pattern of the feet on the battery don't quite match up with the factory pattern.  I thought this was preventing me from being able to dock the laptop into the Ultrabase, however it turns out that it was just a stuck elevator pin in the base itself that was easily repaired with a little pressure.

All in all, while I don't expect non-OEM laptop batteries to have the same fit and finish as the OEM ones, the issue with the locking mechanism not always seating 100% requires me to put a little more effort into keeping an eye on the insert/release battery changes.

I'm a contractor that's had a-lot of cordless tools/batteries over the years. I can say that these batteries run my tools way better than NiCad batteries. First they're lighter, next they provide near-full power to the very end w/o that "tapering" effect we get with NiCad. The fuel gauge is a huge help. The fact that these batteries retro fit NiCad generation tools is really a great thing for all of us that have the solid NiCad tools with some of the not-so-solid Power-Plus & older Milwaukee NiCad batteries. Milwaukee was the first to introduce Lithium Ion technology to power tool batteries and they did it well with the V18 line. Five star except for the price-vs-value aspect.

Went threw all the reviews and decided to take a chance,I use my drill almost every day and was really surprised that this battery lasts as long as Milwaukee that is double the price going to buy another.

I have two of these and they both work great! Never have a dead battery, even in the dead of winter and I live in Wisconsin.

Like a lot of people, I've had more than my share of junk battery powered drivers.  Either the batteries last for all of 15 minutes or they barely have enough power to drive a 2" screw through a cold stick of butter.  I'm happy to say that this driver from Milwaukee does neither.  The battery life is outstanding, and after 2+ years, both batteries that mine came with are still holding at nearly full charge.  Power wise, this has done everything I have asked of it.  From assembling kids' toys to driving hangers into studs to drilling through an attic stud for a cable outlet relocation, this tool hasn't balked yet.

I ordered this battery as I have many Ryobi tools but only one Li-Ion battery. They just keep going and going. We were installing vinyl siding on our house and were screwing it in place. We can work all day without having to recharge the batteries.

I inherited a Milwaukee 18v drill but it didn't have a charger. and they were too expensive at the big box store. bought this one and it works great

I own a bunch of Ryobi one+ tools and it's always a struggle to have a good battery that is charged for them. I started off with two Ryobi batteries and one of them recently died so I was looking for a replacement. I found this aftermarket battery at a fraction of the price as its name brand counterpart and decided to give it a whirl. The battery has been nothing but fantastic - it is much bigger and higher capacity than the batteries I am used to using and runs my tool for a much longer time period the feature I have found I like the most though, that was not present on my other batteries, is a button that activates a LED light that shows you how much battery life you have left in the battery. This is a small feature I wouldn't have thought much about but when using tools it is very helpful, and how to prepare for needing additional batteries if you need them. Only time will tell long longevity of this battery but I will update this review should fail.

I purchased this to go with one of the Milwaukee power tool kits I owned.  I had several M12 RedLithum batteries and I always seem to need a good bright flashlight when I am working on a project.  I like the rechargeable battery flashlights so I thought I would try this one.  It has a Xenon incandescent bulb so it is very bright and with the powerful rechargeable battery it provides light for long periods.

The head flexes in varying degrees from straight to a full 90 degrees and the flashlight has a powerful magnet that allows you to store it on the side of your refrigerator or hang in under the hood of your car when working.

One thing to be careful about it that the Xenon bulb gets very hot and the glass lens gets hot so make sure to let it cool down before you store it.  It can also burn you, so be careful.

There are two things that set this style battery apart from the original. The first being the NiMh technology that is engineered to resist the sulfide buildup inside the batteries that led to premature failure. This is referred to as the "memory" problem in the original NiCd batteries. The second feature is the added capacity that provides for longer tool run times between charges. My old batteries were below 2000mAh so the 3000mAh is a welcome performance boost for me. I like this battery and plan on ordering a second soon so I can have one on the charger while the other is in use. The construction of my battery was flawless. The release tabs operate smoothly and the electrical contacts line up perfect. The batteries are slightly taller due to the added capacity so take that in consideration if you plan on storing the batteries in the original driver case slots. I used a Dremel tool to cut away the plastic tabs in my case so they could fit & it looks like it was made for them,

Excellent capacity battery for my Bosch 12 volt tools. Allows for longer working times and really doesn't add much weight even though its bigger than the standard battery.

I purchased this when Amazon had a Bosch sale.

I checked out the other reviews and decided to get this Lithium-Ion cordless impact driver.  I used so often in house. I love it. Although it's only 10.8-Volt, less powerful than a lot of the 18-V driver on the market, it is light weight and easier to handle than the more powerful ones. The power is enough for all the jobs I did, such as assembling furniture, taking down cabinet doors, tightening chair screws. Li-ion batteries last longer than the NiCd rechargeable batteries and don't have the memory effects. The included extra battery made the charging and switching really easy. It only takes 30 minutes to charge. I feels nimble in the hand. It works great with Milwaukee shockwave bits.

I bought this because my original 19.2V Crapsman Ni-Cd batteries died. Last holiday season I received an Impact Driver with C3 Lithium battery so was able to use my drill and Impact Gun again. Anyway-- I wasn't going to drop ~$50 for replacement batteries that weren't Lithium but stumbled across this.

I read the reviews regarding the latching mechanism, and the battery I received seems to snap in to my drill pretty snugly, so perhaps the manufacturer addressed the issue.

Tip: Don't leave these on your charger too long; I think I killed my Genuine Craftsman batteries that way, despite the smart charger, and judging by the other feedback on these batteries, I'd hate to see a catastrophic failure.
I received this battery at a discount in exchange for my honest and unbiased review, but it worked out well because I was looking for such a battery. $28 is still very reasonable, provided it holds up for a year or two.
