M18 18-Volt Lithium-Ion Compact Rechargeable Battery is rated 3.6 out of 5 by 36.
Rated 5 out of 5 by from Been using m12 and m18 tools for several years and have had great service from tools and batterie... Been using m12 and m18 tools for several years and have had great service from tools and batteries. I use them every day in plumbing and electrical service business and I don't baby them. I have had a couple units have to be sent off for repair but owning around 15 different units that's not a big deal. Have not had but one m12 battery not hold a good charge and its 5 plus years old. For repair if you go online and fill out the forms Milwaukee will even send you a shipping label for free shipping for repair. I usually get a tool back in less than a week. I have a 1/2" M18 FUEL hammer drill that will drill a 1" hole in a 8" concrete wall with no problem and not use up the battery. Not sure about the battery life or the warranty hassle, it's always worked great for me. THANKS MILWAUKEE!

The battery pack came in only a few days. Such prompt service! The only thing is... the box it came in could have held a small fridge. We got a good chuckle from that! No problems with the battery. Fits perfect. Holds a good charge. Making our life easier doing projects.

Rated 5 out of 5 by from Cant beat Milwaukee! I have several Milwaukee M18 tools, (purchased from HD) and I have not found fault with any of them. This small, light weight battery only adds to the versatility of the tools. It is designed not to fit the larger M18 tools like the 6.5 inch saw, but for work in tight places it is perfect with the smaller tools. I have 2 of the larger batteries for the heavy tools. This works well with the drill and the impact driver and the work light, don't let the smaller size fool you, it will stay with you all day for for tight place work. Like I said you cant beat Milwaukee! willway
