HP35s batteries problem

[mcjtom]

Hi,

I just got a new HP35s calculator, which came with two CR2032 batteries. I inserted the batteries (I believe properly). When the ON button is pressed, the display turns on, shows an empty battery symbol and then the calculator turns off after a few seconds.

I thought that somehow the batteries that came with the calculator were empty, so I just bought two new batteries. With the new batteries the calculator does exactly the same thing (i.e. turns on for a few seconds, shows empty battery sign and then turns off again).

What am I doing wrong?

Cheers!
