Nikon d80 won't start after changing sd cards

Just restored a nikon d80 after it was sitting on a shelf for a few years. Batteries were dead so I ordered a new pair and they worked great for a week. However today I changed sd card and it suddenly stopped working and won't say there is even a battery in it.

Hi @hazzathom

Did you make sure the formatting was correct

Most cameras use FAT32 as it’s compatible with most OS’s

Thanks:-)

Hi @hazzathom,

Have you checked that the battery is fully charged, you didn't say?
