Next generation smart watch
Highly improved chipsets offer much more functions inside the smartwatch while at the same time power consumption is reduced. Usage time of 2 weeks without recharge allow high user acceptance and satisfaction. New display technology reduces power consumption even further and allow thinner design and lower weight.
Battery challenge
Highest energy density, robustness and thin housing design of the battery cell is decisive to user acceptance design shape and therefore gets highest design attention.
Technical Solution
The round flat form factor, the robust stainless steel housing and high energy density of the CoinPower series fits perfectly in to the dedicated shape of the whole device. With its patented cells design, VARTA CoinPower offers the perfect energy density across miniature Li-Ion cells on the market. Low weight and a broad range of cell sizes allow flexible design shaping and keeps the smart watch thin perfect for comfortable user experience. For example look at our CP1240 A4X cell:
