Varta announces rechargeable batteries for hearing aids

Rechargeable Lithium-ion batteries with a high-energy density and capacity will be unveiled at the Wearable Technologies Conference in San Francisco for wearables and hearables (hearing aids, over-ear headphones and wireless telephony ear buds).

The CoinPower button cells have short charging times and are robust and reliable, says Varta.

The smallest models, the CP 7840 and CP 9440, are just 4mm thick and have been developed for headphones, fitness wristbands and vehicles’ smart keys, as well as in medical equipment.

The CoinPower micro batteries have an energy density that is up to 30 per cent higher than comparable batteries available on the market, says Vara. The CoinPower series will be produced using fully automated processes in Varta Microbattery’s European production sites in Ellwangen.
