4 AAA rechargeable and interchangeable batteries solution for philips dcc 170 potrable recorder

After week of testing - Works fine.
The dcc 170 recharges all 4 AAA batteries inside.
The batteries are completely interchangeable.


Amazingly creative!

Have tried to reproduce this famous idea and in theory this works. In reality however most AAA batteries are a little to big in diameter so they squeeze the wall plastics apart and you can no longer close the player properly.
Solution would be to sand or dremel the inner wall a bit but I don,t want to do so .
So maybe it works with some batteries but not all…
