within the last 3 weeks my mainly used hp41cx had corrosion on the minus pol of the left hand battery. It happened two times. I can't switch on the hp41cx. After cleaning the (-) pol on the battery, it works again.

This is my most loved calculator. I am afraid if there is a current the reason, when the calculator is switched off. Do you know this problem?


You have to worry about the calculator terminals. If it is clean, just replace the batteries. Your bateries are old, they can leak at any moment.
