Great Porduct That Needs Better Manual
It does what it supposed to do. The two sticking tabs on both sides were the newest edition to prevent usage with 20V Max Premium batteries as it they are not compatible with some 18V equipment (see the manual for the list). So all of the people who had hard time removing batteries is because those are premium batteries (5Ah and up). For regular 20V Max Li-I batteries those tabs on the adapter are not on the way. Attached picture that explains it.

    Not perfect, but it does what it is supposed to do. It does provide a method to use the 20-Volt MAX batteries with old 18-Volt tools (Drill and Saw). While the adapter fits the tools and clips in properly, it does not fully fill the space at the bottom of the tool that the old battery took. I also found that the 20-Volt MAX batteries slowly discharge when left in the adapters. I now keep the adapters in the tools and never leave the battery in the adapter when not in use. The batteries no longer discharge while stored. I don't know why the adapter itself is so large or angled. The combination of the adapter and 2AH battery is similar in size to the old 18-Volt packs that I had, but the adapter could have been less than half the size that it is. If you have multiple 18-Volt tools, getting these adapters to extend the life of the tool and use current battery technology is the way to go.

      This is great you can keep all your 18 volt tools and still use the same battery as the 20 volt tools. Money well spent. Because in was thinking about getting rid of my 18 volt so I could use the same battery for all of them.

      No need to waste money on outdated battery technology ( XRP battery, which cost the same as lithium batteries) which discharge in your tool box by themselves, enough to delay you in starting a job, or invest in a newer lithium bare tool, when all your XRP tools work fine and will work even better with the latest battery technology, just get this adapter and maybe a new kit on sale with 4 ah or 5 ah batteries even 2 ah are great ( more or bigger batteries even better ) and your work day will go faster and longer. Best addition of my tool box in a while.
