Is it normal for the Congratulations message on the LCD screen to slowly fade after plugging in the battery?

I have checked the battery and it appears fine. I do get the message, but after a couple of seconds it fades out. Disconnecting the battery and reconnecting it after a couple of seconds and it works again then fades out.

Turns out it was the battery that came with the kit. A brand new Duracell fixed it right up.

The kit battery looked fine on a multimeter, but when measuring its output voltage when plugged in it steadily dropped.
