These are made of serveral small nickel batteries and if one goes, it will not charge. Some people have beable to take the 16v apart and test each batteries and replace the bad ones.

Panasonic EY7540 impact driver. Does not go into reverse on 1st

The forward/ reverse switch is hanging up and the rotation of the drill is switching it, then it changes direction. The switch needs a little TLC and a good cleaning. Blow it out.

How to take apart panasonic battery pack ey9230

The screws are a T10 tamperproof torx. After removing the 4 of them you need a small pick to push into the holes on both sides of the battery while applying some upward pressure on the top case. There are small clips in the top housing that you are trying to release. Let me know if I can help further
