BOOSTXL-BATPAKMKII: Lithium Polymer Battery Dead?

Part Number: BOOSTXL-BATPAKMKII

Hi,

I have not use my BOOSTXL-BATPAKMKII for a long time. I charge the Lithium Polymer Battery for 6 hours and the voltage measured is 0.2 mV. Is the Lithium Polymer Battery Dead?

What I observed also is when I connect the BOOSTXL-BATPAKMKII to power supply the CHARGE ACTIVE LED turns on briefly. Before the CHARGE ACTIVE LED is on during charging. With this observation I somehow suspect that there is some problem also with my BOOSTXL-BATPAKMKII.
