Xbox Controller Rechargeable Battery (Genuine, Battery Only)

Purchased on Amazon at the end of March this year. After purchasing, I realized it was incompatible with the controllers I own, so it has been stored in a dark place since then.
This is for the battery only, but I am offering it at a low price. It is unused.

To reduce shipping costs, I will inquire about packaging after purchase. Please consider purchasing only if you are able to accommodate this request.
