VARTA’s CoinPower, the industry’s first rechargeable tiny lithium-ion coin cell, is powering the IoT by meeting the market demand for more energy in smaller sizes.

With 6 patented innovations, CoinPower is now the preferred battery choice for manufacturers of space-constrained, portable devices that have high power drain requirements on batteries with 60mAh, 85mAh or 120mAh of capacity. Used in Bluetooth, wireless, wearable, medical and industrial electronics, they ensure durability, reliability, high capacity and long cycle life.

These high performance cells are enclosed in a strong, stable stainless steel patented casing which provides reduced risk of damage during assembly into end equipment and high tolerance to shock and vibration.

The footprint of the cell protection circuitry is considerably smaller than complex PCBs associated with custom battery packs. An integrated safety mechanism activates when the cell is subjected to abusive conditions and disconnects and shuts down the cell before it enters an unsafe state. The cells are rated to withstand extreme 12V/3C over-charging conditions – well above industry standards of 1C.

  • 10% to 30% higher density vs. all other competitors in the microbattery market
  • Extended life time 500 full cycles at 80% of initial capacity
  • Highest drain capability
  • Best mechanical stability (compared to pouch cells) almost zero swelling by design
  • Easy to handle in production, hard case button cell design
  • Not sensitive to scratches and dents
  • Extended efficiency safety
  • Fully automated cell production with the highest reliability
  • Technology protected by key innovations – 6 patents filed
