Tamagtchi Connection V4 wont connect?

Okay so-
Earlier today I replaced the batteries on my two tamagotchi connections v4.5 and v4, set the correct time, and tried to connect them via visit, but they wouldn't...
I'm pretty sure it's the v4 that wont send the signal thing properly, 'cuz the 4.5 will try to connect but will end up with a failure, and the v4 will keep on saying connect until it'll eventually say fail, normally 30 seconds later than the 4.5... The battery for it might be a little old, I don't know... Anybody know whats wrong? I really want to connect them so I can marry them soon...

The same exact thing happened to my V4 a few years ago. Try putting in a fresh battery and see if that helps. You could also try downloading and resetting your V4, I've heard that helps.

Ah, thank you very much! I'll go look if I have any fresh ones~
