Great Battery Storage Case
Color: Large
I was needing a better solution to store and transport all the Dewalt, Milwaukee, Makita, and Porter Cable lithium ion batteries that I have, so this caught my attention. It easily holds nine batteries and some of the dividers are adjustable to help accommodate larger batteries. It was about $40 for Black Friday/Cyber Monday, which is a fantastic price for a specialized case like this one. The case is very well made inside and out, which makes it perfect for either storage and transport. It's got a beefy handle, heavy duty latches, and even has places for a padlock. The foam in the lid, dividers, and case hinges are all also really solid. It's great if you're a particular fan of Milwaukee as this case already comes in black/red to match your tools. Dewalt, Makita, and other brands of batteries all fit in here fine. I've put a variety of battery sizes in here from 3.0Ah all the way up to 9.0Ah and they all fit, but heads up that only the horizontal dividers are positionable (the long vertical dividers can't be moved). This style of hardshell case is perfect in my opinion. I also got one in black and yellow colors at the same time, and will likely purchase more as the need arises. This is a wonderful case and I would recommend it based on my experience so far.

Very useful for battery organization
Color: Large
I have two of these, forr storing my large amount of Milwaukee batteries. The quality is great, and I like the organization it provides. some of my larger capacity batteries are a little snug when I put them in the case. The case, even when full, is very easy to move around.

Nice but milwaukee works better
Color: Large
The box is nice but the box will only be able to fit 6x M18 6.0 milwaukee batteries and leave 3x small slots which is a waste so I spent a few extra bucks on the milwaukee PACKOUT 20 in. And able to fit 12x M18 6.0 batteries

So good I bought two
Color: Large
This holds my Milwaukee batteries and charger perfectly. It keeps them safe from damaging, which could result in a fire. Heavy duty quality at a good price. I like it’s durability and functionality.

GREAT QUALITY CASE OUTSTANDING PROTECTION
Color: Extra Large
Item was just as described. Appears to be well made, material is very sturdy, case lock pads are sturdy and positive locking mechanism. Internal pads are abs covered with soft rubber material, compartments are adjustable to whatever your needs require. Case was reasonably priced and made to function as it should. I would recommend this item with no reservations.

Doesn’t fit like it shows in the picture and seems cheap.
Color: Large
False advertisement, it doesn’t hold batteries in a row and the charger doesn’t fit at all the way it’s shown in the photo. Don’t buy this item. Make your own.

Great case and looks great too
Color: Extra Large
You already know how expensive your batteries are for your tools and I would always forget where I put them until I got this. They protect and organize your batteries so you’ll always know where they are. It also looks really good too.
