You can't really replace a battery in a greeting card because the battery is sealed between two pieces of card stock. If you wanted to separate the paper you should be able to get a button battery the same size and glue it into place to get the greeting card working again.

I paid 5.00 for one to send to my nephew because he likes musical greeting cards. It came back returned because I had the wrong street address number on it, which I wasn't sure of to begin with (residential home). I took it out of the canceled enveloped to replace env. and re-send. When I did, I opened the card and it wasn't working!! I took out the 3 cell batteries and replaced them in case it had gotten activated during shipping and batteries ran out. There was a little tab on the side of each compartment that lifted up and then I prodded each battery out (pretty easy), replaced with new ones and it still didn't work. So, I guess it somehow got damaged during transit, even 'though it doesn't look damaged. Something must've happened to the speaker. I'm wondering if all 3 cell batteries were face down. I would think so. Still wondering why it won't work. $5.00 plus the double postage so far wasted. He's worth it, 'though, if I can get it going again. He's also worth buying a new one for, which I'll probably end up doing.
