Safe so long as you make sure the terminals and cables are insulated. Just wondering how the battery is to blame for the fuse though?

Mark is correct (usually the case!) but regarding the fuse I was thinking that the second battery would lower the demand on the alternator and therefore be less likely to blow the fuse. Also, the fuse melting and not blowing suggests poor contact at the fuse holder, maybe replace the holder or see if you can clean the contacts.
