Synergy ScienTech has disclosed it will begin production of button batteries mainly for use in TWS devices at its factory in Kunshan, China, in third-quarter 2020.

The initial monthly production capacity will be 100,000 60mAh batteries, Synergy noted, adding that it is developing models of 65-70mAh.

Synergy said it has obtained orders for 10 million button batteries.

Synergy said it originally planned to kick off the production in the second quarter, but China-based equipment suppliers have had to delay shipments for 1-2 months due to the coronavirus outbreak.

Synergy said it resumed production at the Kunshan factory in February, with the number of workers returning to work rising, and 90% of workers are expected to have returned by the end of March.
