As I remember the original post, the Ryobi is 5 or 6 years old?? That being the case, even though the batteries seem to be working now, chances are they won't be working much longer. I'd keep both drills.....you would be surprised at how handy it is to have a second drill, You could even use it as a loner and not have to be so concerned about having it damaged or lost or out of pocket when you need it!!!
