CUSTOMER REVIEWS

Rated 4.7 out of 5 by 51 reviewers.
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.

Rated 5.0 out of 5.0 by Well Designed, Very durable, Long life This is a well made product. Milwaukee is really setting the bar higher everyday. This battery is a nice upgrade to anyone's inventory. The M18 4.0 is an attractive battery that packs a punch, is extremely durable, and has constant power throughout the whole charge. I would say the only downfall to the battery is the added weight, if you are upgrading from the compact battery. To me the extra weight is not an issue, but others might feel differently about this. The added weight is less than two of the M18 2.0 batteries. The extra run time from each charge is far more important to me. I have four of these batteries. I use my drill (M18 Fuel) everyday with light to medium use. I would say roughly 20-30 minutes 5 days a week, on average, with on and off use. One battery will last on my drill for a minimum of a week. I alternate the four batteries between a few different Milwaukee tools I have and end up charging all four once a month maybe every three weeks. This is all dependent on how much you use your drill. Even on days I have used my drill all day long I only went through one battery. The battery itself is made of a durable plastic with a rubber bottom and a bit on the sides. I have found this useful as I do not scratch tables when I set my tools down. I have used these for door stops, light hammering, knocking holes in walls. These are probably not the best ideas but they still work like new. I would recommend this product to anyone November 1, 2014
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
Rated 3.0 out of 5.0 by Rigid warranty Bought drill kit with extra battery advertising lifetime warranty. Submitting warranty info was told battery did not qualify for extended warranty, and I am still trying to get extended warranty on drill kit. Jumping through all the hoops Rigid has set up to get warranty is irritating January 27, 2015
Rated 5.0 out of 5.0 by Great battery The battery has great run time especially when using my 4-1/2 angle grinder and brushless 3speed impact driver when doing a fence January 15, 2013
Rated 5.0 out of 5.0 by Great product ! Home Depot sells the excellent Milwaukee line of tools. These extended use batteries mean you will be spending less time charging and more time accomplishing your tasks. This nice thing is this fits all the M18 products. Would definitely recommend it if you have the tools. February 26, 2013
Rated 5.0 out of 5.0 by I love this battery!!! I really love this battery. Can't speak to much as far as the longevity yet. It has great runtime!! And it really adds good torque to my 2602 hammerdrill. The fuel impact and the grinder!!! Cant wait to see what it does as I expand my milwaukee line. February 17, 2013
Rated 5.0 out of 5.0 by Great Battery I use this battery on a heavy duty hand held sewing machine. The life of the battery is Great!!! August 19, 2014
