VARTA Microbattery Launches Three New Lithium-Ion Cells for Wearables at the ISPO Munich 2019

VARTA New Lithium ion cells

Athletes and sports enthusiasts are increasingly relying on smart wearables to monitor or enhance their performances. Wearables and hearables are now routinely used as practical training aids for many different sports. Reliable batteries are essential for wearable devices that produce precise and continuous records of vital data.

At the ISPO Munich, the world’s largest trade fair for sports articles and sports fashion, VARTA Microbattery will demonstrate what is currently possible in this field by launching three new lithium-ion cells at the shared WT | Wearable Technologies Pavilion in Hall C6, Stand 706, from 3 to 6 February 2019. VARTA Microbattery will present its CoinPower series at the trade fair in Munich.

While the performance level of wearable devices is increasing, they are becoming smaller and lighter. Therefore, the amount of energy provided by batteries has to be adapted accordingly.

VARTA Microbattery will present its CoinPower series at the trade fair in Munich. This includes three new flat Lithium-I on cell types: the CP 0854, CP9440 and CP7840. Their cylindrical shape and high energy density make them an ideal energy source for wearables and hearables.

“The new cells are the result of our ongoing drive to improve miniaturization. This is of benefit to manufacturers, since they can make their devices increasingly smaller and flatter,” Matthias Dorsch, Product Manager at VARTA Microbattery GmbH, explains.

The coin cells with high capacity and fast charging capability are easy to install in end devices. The strong steel housing of the cells ensures high tolerance against impact and vibration. The CoinPower series has produced several patents, including the i-Lock system, which together with the circular form enables up to 30 percent higher energy density than comparable batteries on the market.


As the parent company of the Group, VARTA AG is active in the business segments Microbatteries and Power & Energy through its operating subsidiaries VARTA Microbattery GmbH and VARTA Storage GmbH. Already an innovation leader in the microbattery sector and a market leader for hearing-aid microbatteries, VARTA Microbattery GmbH also aspires to market leadership for lithium-ion batteries. The Group’s operating subsidiaries are currently active in more than 75 countries around the world, with four production and assembly facilities in Europe and Asia as well as distribution centers in Asia, Europe and the United States.
