Query: Battery won't fit

On 11/16 I bought a Casio Exilim EX-Z80 8MP Digital Camera - Black, additional battery Adorama NP-20 Lithium-Ion Rechargeable Battery for Casio Exilim Series Digital Cameras and Casio Exilim EX-Case7 Leather Business Card Holder Style Universal Camera Case for Exilim EX-S10 Camera (Black). I am quite satisfied with everything with the exception of the battery. Even though offered as a battery for camera I bought, it is of different size and won't fit into my Exilim.
