Hi there!
First I would return the battery and get yourself a new one and see if this fix it.
If not, then it's most likely that your battery charge IC died on the motherboard and need to be replaced.
This is the one you need: https://www.aliexpress.us/item/3256806545737224.html?pdp_npi=4%40dis%21EUR%211.97%211.42%21%21%2114.52%2110.45%21%402102e22d17370450326716531d115e%2112000038120245534%21affd%21%21%21&dp=EAIaIQobChMItpjf-62ViwMVeIKDBx3weAxdEAQYBCABEgLh8vD_BwE&gad_source=1&aff_fcid=291e4c93d7ea499db960559a9ed44fa6-1737962279283-08418&aff_fsk&aff_platform=api-new-product-query&sk&aff_trace_key=291e4c93d7ea499db960559a9ed44fa6-1737962279283-08418&terminal_id=9115f7756b6d4540a4fb9688e2537090&afSmartRedirect=y&gatewayAdapt=nld2usa4itemAdapt
Hopefully it's just the battery, but 1 way to be sure..
