Misleading product description.
This product page clearly advertises a pair of 3.85V, 75mAh (0.29Wh) batteries, sold as part of a kit intended for repairing Sony WF-1000XM4 headphones. Accurate battery specifications are critical for this repair, as the headphones and their companion app rely on specific battery parameters for proper functionality.However, the batteries I received were rated at only 70mAh. This discrepancy affects both the battery life—reduced by approximately 7%—and the accuracy of the charge level reported by the app, which from my understanding expects a 75mAh battery.It is unacceptable to advertise precise specifications and then deliver a product that does not meet them.
