Why does the MP3 player start only when charging?

Question

Rechargeable batteries

There is an mp3 player. It lay for a long time and stopped turning on. Decided that the battery, bought and changed. But as a result, the player itself does not turn on, but only if you turn on the charging. And after that it works fine and the charge level shows normal.
Tell me, maybe you need to somehow launch a lithium battery for the first time because of the built-in protection?

Answer 1

Yes, there is an overdischarge protection board. The first time after installing a new battery, this may be normal, but if this continues, the battery is bad.
