Varta, a German battery manufacturer, has seen significant volatility in its share price over the last year. But according to the findings of Counterpoint Research’s recent report – “Global Micro-Battery Market for Hearables (TWS) 2019-2020”, the concern over Varta is likely misplaced and overlooks the recent surge in the true wireless hearables market, which is growing much faster than previously expected. Counterpoint expects that Varta’s sales volume will grow 57% year-on-year in 2020. The research also highlights that concerns over Varta’s temporary supply shortages will be solved and are not fundamental issues relating to Varta’s product or price competitiveness. Varta is also alleging that some Chinese companies are infringing its patents and it is initiating legal proceedings against those companies.

The size of the global market for true wireless hearables is estimated to have reached 120 million units in 2019, according to Counterpoint Research’s Hearables Market Forecast. It grew faster than expected in early 2019, ultimately more than doubling the 46 million units achieved in 2018. Accordingly, the related upstream supply chain has benefited from the boom, with micro-batteries being a key component.

Counterpoint Research forecasts that the micro-battery market will grow 90% in 2020. As the canal-type premium hearables such as AirPods Pro and Galaxy Buds are becoming ever more popular they will also influence the share among the different micro-battery types. Coin cell batteries will jump from around a quarter to well over half the micro-battery market, with Varta maintaining its leading position. Samsung SDI and LG Chem will also benefit from this rapid growth.

Cylindrical micro-batteries, that made-up 48% of the micro-battery market, will decline to represent less than a fifth of the much larger overall micro-battery market in 2020. LG Chem will likely remain the leading player of this battery type.

Pouch (polymer) micro-batteries, for low-end hearables, which are largely driven by small Chinese players, will continue to account for around a quarter of micro-battery sales.

Liz Lee, Senior Analyst at Counterpoint Research, said, “As demand for coin cell batteries exceeds the current supply, more battery companies will commercialize coin cell batteries and expand their capacity. However, as with all rechargeable lithium-ion batteries, there is a safety risk. Leading hearable manufacturers will be aware of the potential brand-damage arising from product failures and will select battery suppliers based on factors including quality. Thus, only a few companies with long-term track records of safety and reliability, are expected to benefit.”
