Answer: 
Hey, ChuckW
I own several M 12 tools. I have found that the low AND high capacity batteries are interchangeable. My small driver will stand up with the larger battery. All the tools have more "oomph"" with the larger. Sometimes in tight spaces, big is a problem.

Assemble and insert the piston rod. Pull the trigger while pressing the button to the side of the hose. I have found as with any grease gun to form a slight dome shape with the grease on the insert end of the tube. The objective is to eliminate the air void from the start, while not having the grease ooze past the threads while screwing it in. I scrape the left over grease from the last tube with a popsicle stick to do that. You can also use some grease from the piston end.
BE CAREFUL! THAT METAL EDGE IN THE GREASE TUBE CAN BE SHARP! I have also found that temperature can be a factor. If it is cold, I take the grease inside to warm up. It flows easier.
If it is stubborn, unscrew the hose and that eliminates some resistance to getting a flow.

Rated 4.7 out of 5 by 36 reviewers.
Rated 5.0 out of 5.0 by Works great Work great got grease into fittings that I usually have a hard time getting. Can grease my bobcat in less then 10 min August 2, 2016
Rated 5.0 out of 5.0 by great tool easy to use, perfect for tractor maintence, works with other 12 volt Milwaulkee tols July 7, 2016
Rated 5.0 out of 5.0 by Greased Lightning Pulling the trigger of this grease gun sure beats operating a lever, or lugging one of those heavier battery units. I love the design and it works better that any I've had, including a pneumatic. I bought it primarily to grease all the fittings on my loader / backhoe and it has cut my time in half! I have been using the 4 AH battery it came with to run my other M 12 tools for the extra oomph it has over the 2 AH battery. Couldn't resist the cliché title:-) May 22, 2016
Rated 5.0 out of 5.0 by Love this tool As a disabled vet that had a injury to my right hand and having to use the manual type grease gun was always a problem for me. It always took me a long time to grease all my tractors and this tool saved me a lot of time cause all I had to do was hit a zerk fitting (grease fitting) and in seconds I was done. I just wish I would have bought one of these earlier because this is one of the best investments I have made when it comes to tools for this type of jobs I have to do all the time. I only see one drawback is that the carrying case should be in a more protective case. Once I am done with all my tractors all greased up I will hit up my cars and truck. November 14, 2013
Rated 5.0 out of 5.0 by Excellent product I purchased multiple drills. They are lightweight and very easy to assemble. Milwaukee tools are the best. Thank you for easy ordering online and fast, free shipping. June 7, 2016
Rated 5.0 out of 5.0 by Great Grease gun Love the carry case, purchased for the projects around the house because I was tired of the hand operated grease guns...... April 19, 2016
Rated 5.0 out of 5.0 by great quality tool wonderful tool. very easy to use and increases productivity March 15, 2016
Rated 5.0 out of 5.0 by Decent grease gun My first tube of grease primed right through, pumped grease into zerks that would have been trouble for a regular gun. It works great !the second tube wouldn't prime, but it was my fault; after reading the instructions on priming, it primed just fine(put in the tube of grease, with the handle extended and locked, put pressure against the grease while pushing the prime button, works great)I love this gun, but I just purchased the two speed Millwakee, I use both now. The two speed allows me to put out more volume, like when covering a fifth wheel , I like this one better for crawling in tight spaces, it is smaller and lighter. Over all, I really recommend the M-12 October 6, 2015
