Motorola V171 batteries USA<>Europe

Hi!

I bought two batteries to my cell phone Motorola V171 (bought in Spain) from
a USA store at Ebay and the electric contacts are physically incompatibles.
Motorola V171 have diferent batteries in USA and Europe? The two batteries
have the inscription "FOR MOT V300/600" and the electrical contacts are at
the centre and not at one side like original battery in my cell phone.

Thanks
