Replacement battery is dead after 14 months

Hello,

I bought a replacement battery for my mac (MacBook Pro 13" Function Keys Late 2016), order date March 12, 2022.

Now, after a bit more than a year and 320 cycles, the battery is dead. Mac runs on battery for about half an hour. The battery charge is drained fast from 100% to about 70/75% and the mac shuts down.

One more "curious" thing, the battery has been produced ten years ago (see image taken from coconut battery). It does not seem ok to me.

Could you help me?

Thank you
