Replaced battery, watch not coming on.

I replaced the battery. Went easy with the online instructions. I did not receive any adhesive with the battery. I substituted. The watch display is blank. Put in charger overnight, screen shows 100% with USB power symbol, not battery symbol. Switched back to my original battery and it works normally. Only problem is original battery is not holding a charge like it used too. That is why I chose to replace it. Is there a step I am missing to get the watch to recognize the replacement battery?

thank you.
