Battery replacement wont help

[ashes2007]

I've had a Tamagotchi and he has lived happily three times but his battery died on his third life so I replaced it:

opened rear cover, used a screwdriver to pry the battery out then pulled it out. I grabbed a new battery, popped it in and closed him up. But he still displayed the "dead battery" symbol

any help?

Oh. I fixed it by poking reset. I have a new tama tho now

Yay! Glad it's working again.
