Answer: 
It will perform with the same brightness. The running time will be 2/4 or 1/2 the time of a 4ah battery. It will perform 2/5 the time of a 5ah battery.

Rated 4.6 out of 5 by 70 reviewers.
Rated 5.0 out of 5.0 by My m18 4.0 The fan is great for those school with no ac this summer August 30, 2016
Rated 4.0 out of 5.0 by M18 18-Volt Battery Needed an extended capacity battery.. Found this in a blister pack, on the 35% off table in the front of the store. For the price it was a solid buy, wish they would have had two!! August 18, 2015
Rated 5.0 out of 5.0 by Very Good Has a long running life and does last long. Has good power. August 4, 2015
Rated 3.0 out of 5.0 by In the dark Works OK but light is not very bright and it seems a little overpriced for a "flashlight" with no batteries included. September 20, 2016
Rated 2.0 out of 5.0 by not enough light!! I wish that this light was brighter! Also it would be nice if you could adjust the beam! If it could do those two things......5⭐️⭐️⭐️⭐️⭐️ August 27, 2016
Rated 5.0 out of 5.0 by Great little light I added this light to my M18 FUEL drill /driver set works real well, great flood light. it also has a hook for hanging. I have passed the word here at work on this great LED must have lights. April 5, 2016
Rated 5.0 out of 5.0 by Definitely worth the little extra Simply put this is a well made product. It has so far out lasted the rest in run time. If you are taking on a medium sized project and don't want to spend a lot of time changing batteries. You have found the solution. The run time is more than the 3ah. It is not that much more in price than the 3ah. So is your time worth it ? Milwaukee m-18 tools already have plenty of power. You are just getting more run time. I like the fact they give you every bit of that power until the battery is depleted. No slow drain as the battery goes down so does the power. A big plus ! No cords, no hassles, just go to work. April 23, 2013
Rated 5.0 out of 5.0 by LONG LIFE!! I bought this battery because I had 2 original compact batteries (not 2.0) and they worked great, but on prolonged use I had to charge them often. However, I did like that it took only 20 mins to fully charge the compact. As for this battery, it obviously weights a little more, but the power and LONG LIFE is well worth it!! This battery goes all day!!! On the flip side, it take a bit longer to charge.. 45 mins?? I would DEFINITELY recommend this for anyone with the compact batteries as it gives you ultimate versatility. One more thing to mention is I noticed using this battery with the drill or impact can make it more difficult to fit in tight corners, but that's my only complaint. February 19, 2013
