Official Microsoft Battery Pack stops charging within a 3 month time span.

Bought this again from Greatest Purchase in March of 2023 and possibly across the twentieth cost, it doesn't go previous this "crucial" degree. I attempted totally different cables, totally different ports, totally different controllers, updating controllers, desyncing controllers, cleansing with 99% isopropyl alcohol on each contact and so forth with no success. The charging animation seems, however thats it, the battery life stays the identical. I perceive these weren't meant to final ceaselessly, however lower than 4 months is unacceptable and ridiculous. Im previous the return date so I cant even do this, plus I cant discover my receipt anyway. I've learn some critiques on Greatest Buys web site with lots of people having the identical problem. Is there a approach to repair this? Any way more dependable rechargeable batteries i can purchase as an alternative of MICROSOFTS OFFICIAL PRODUCT? Thanks.
