VARTA Microbattery presents latest battery generation at the Wearable Technologies Conference in Munich


They can be worn close to the body, directly on the body or even in the body - wearables are conquering more and more areas and are becoming increasingly self-evident in everyday life. The development of this global growth market would be inconceivable without reliable, energy-efficient batteries. In wearables, the batteries determine performance and service life. At the same time, they have to meet growing demands and should become smaller, lighter and more efficient.

VARTA Microbattery (Ellwangen, Germany) will be demonstrating what is already possible in this field at the "Wearable Technologies Conference" in Munich on 30 and 31 January. Visitors can look forward to short product presentations by VARTA experts in the style of Elevator Pitches.

VARTA Microbattery presents its CoinPower series at the "Wearable Technologies Conference" in Munich. The product line consists of the CP 1254 A3 and CP 1654 A3 as well as the CP 1454 A3 with a capacity of 85mAh, a diameter of 14.1mm and a weight of 2.4g, this microbattery meets the customer's requirement for more capacity at a smaller size. The capacity of the CP 1254 and CP 1654 models has recently been increased. “Its compact and stable construction in cylindrical form, coupled with a high energy density and extreme performance, make the CoinPower cell an ideal energy source for all wearables and hearables. Fast-charging capability, high load-bearing capacity and a robust construction round off the profile of the CoinPower series ,” explains Herbert Schein, CEO of VARTA AG.

In addition, a high-capacity button cell offers further advantages: Simple installation in devices - due to their strong and solid stainless steel housing almost without risk of damage – as well as highest precision in the mechanical design of the battery arrangement. The strong steel housing of the cell also ensures a high tolerance to shocks and vibration.

In the growing area of Bluetooth headphones, there are numerous applications for the small energy dispensers - as well as in fitness trackers and other wearables. The CoinPower series has produced several patents, including the i-Lock system, which together with the circular shape allows up to 30 percent higher energy density than comparable microbatteries on the market.

The company will be showing the rechargeable series of Coin Power cells in action on site. It is used, for example, in one of the first wireless in-ear headphones from the young start-up company Bragi. Also in the Cosinuss One a CoinPower battery provides the necessary energy. The device looks like a cordless headset, but is a heart rate monitor in the ear that also measures heart rate variability and body temperature. The data can be read out on the smartphone or Smart Watch after training.
