I don't know how batteries work over there in Romania but you ''might'' have used unsuitable batteries. Sometimes there's batteries that will still fit but may have more power, thus, causing an overvoltage of some sort and overheating. If you used good, suitable batteries, then it could just be a defective unit. I would look and see if other people are reporting the same problem.
