The soldered battery which is running at 3.7 V with 31 mAh. This sums up to ~0.11 Wh. For those interested, the button cell has a ~10 mm diameter and a height of ~4.4 mm.
In comparison we have the Galaxy Buds Live (0.2 Wh) and the Galaxy Buds+ (~0.31 Wh) button cell next to it. With the AirPods Pro battery at 0.16 Wh, the Nothing ear(1) has the smallest battery of the lot.
