I wasn't sure where to post this, I'm a newbie so be kind

I bought a Polaroid i735 for friend for Xmas. I'm making sure it works to my standards before giving it and one thing I want to know is if a CR-V3 will fit. I use low discharge nimh's normally but if a CR-V3 fits I may splurge on a lithium ion rechargable. The bay is odd shaped but it isn't completly oval and I've noticed that the cr's seem longer than aa's.
