M18 18-Volt Lithium-Ion High Output Battery Pack 12.0Ah and Rapid Charger Starter Kit

This combo pack with the 12.0 and the 6.0 and the quick fast battery charger it's all I need to get started on my project perfect combination pack. I really feel that the 12.0 battery pack puts out a lot of power consistently and allowed my tool to function in the best manner possible

Batteries have lasted all day on equipment we are using them with. One battery per device.

Quick charges and adds lot of power to 1/2 impact

Huge battery but at a cost.......................................................................... This is an unbiased review that is unaffected by the fact that I received this product for free. As proof of impartiality, just click on my nickname and see the average of the ratings I have given over 200 reviews to date. First, the good: This battery has 4 times the capacity as the 3 AH battery so it will last a long time before needing to be recharged. That can be a big plus at a job-site that has little or no access to line power for a charger. The battery comes with a 50% charge from the factory, which is good since that is a very efficient way to prolong the battery life while in storage. I wish the charger had a mode for loading the battery to that level as do some other brands. As for the charger, this is the same charger that can be used with all 18V Milwaukee batteries. It is not a special version just for this size battery, so if you already have an 18V charger, you would not need to buy this set, only the battery. See the photo of the charger part number label. The battery is cost effective when compared to the smaller versions. You would need to buy 4 of the 3AH batteries to get the same capacity and that would be more expensive. Next, the bad: This battery is much heavier than the rest, although for good reason. So that will make for a heavier tool and more labor if the extra power is not needed. And when the battery is discharged, it will take some time to recharge it. If you had two of the 5AH batteries, or three (or four) of the 3 AH batteries, you could have one or more on charge to be ready when the first one was discharged. Bigger is not always better.

It is a pain that all the different manufacturers have their own propriety batteries. I wish they would standardize like regular batteries. Now I have a couple of Milwaukee tools with batteries and this battery and charger I think I will focus on Milwaukee batteries and tools. At least these batteries are interchangeable with the Milwaukee tools and they seem to be powerful and last well. Unfortunately this battery wouldn’t fit in my Milwaukee compact work light because the area for the battery is not big enough. I figured out that I could cut away some of the plastic to make it fit without harming the light. It worked great. Check out my photos to see what I did. I really like that this battery has a “Fuel gauge” which shows how much charge is left in the battery. This is better than only knowing when the battery needs charging because it dies. This battery also has a 3 year warranty which is good. These batteries are expensive. Hopefully as the rechargeable battery technology improves they will come down in price.

This is one hefty power pack! You get the 18 Volt 12 Ah battery, and a rapid charger in the pack. This starter kit can then form the basis of any M18 tool set by adding the tools you need. The charger can also handle M12 batteries. This is the bag daddy of the M18 batteries and is physically bigger than all the others. It is almost 4” deep. In fact, it is a little too big for some M18 tools which were made before june 2018. It seems that someone forgot about tolerances because the battery has been made the same size as the battery ‘holes’ in some M18 tools making it impossible or impractical to insert this battery into the tool! The tools likely to have problems are the ones with a ‘hole’ into which the battery must be inserted. When the battery forms the base of the tool (such as drivers and drills), you should have no problems. I had problems inserting the battery into three of the M18 tools that I have. The Jobsite Fan takes the battery OK, but it sticks out the bottom, lower than the feet of the fan. It can be used. See picture. The battery could not be inserted into the 2130-20 M18 3000 Lumen ROCKET LED Stand Work Light & Charger. It is simply too big, even though it looks like the light was designed with this size battery in mind. I found I could force the battery into the 2135-20 2000-Lumen ROCKET LED Stand Work Light, but I immediately regretted it as it was a huge battle to get the battery out again. I found some fine print on the package stating that service parts are needed for: 2787-20, 2788-20, 2771-20, 2122-20, 2130-20, 2135-20, 2361-20, 2145-20, 2146-20, and 2360-20 made before June 2018. On their website they state that FREE service upgrades for the listed products are available to any customer that purchases a this battery pack (starting summer 2018 you will be able to visit e-Service to request your service part). The battery had some charge already and the charger worked flawlessly to get it fully charged. The charger has indicators that show when the battery is charging, full or defective etc. If you are going to be using the larger power hungry tools such as the big drivers and angle grinders, this battery is going to give you the longest work time. It adds a lot of weight to your tool for sure, so one should also consider buying two lighter M18 5Ah or 9Ah batteries so that one can be charging while you use the second, especially if you are having to hold the power tool up high. Cells made in Korea with additional processing in China. 3 year warranty on the battery. Charger made in China. 5 year warranty on the charger.

It is of very poor quality, the plastics were stuck and it split into 2 parts, I had to glue them with electrician's tape

Love the Milwaukee tools. Needed this for a demo saw and chain saw.
