You're looking for wholesale Li-ion cell batteries for the AirPods 3, specifically the A2647, A2564, and A2565 models. These part numbers refer to the different battery components used in the AirPods 3 (both left and right earbud batteries and the charging case battery).

Here’s a breakdown:

A2647: Battery for the right AirPod.

A2564: Battery for the left AirPod.
