The A4X follows the A4 series and comprises 3.7V micro batteries available in five diameters and three heights, offering low impedance and a maximum typical capacity of 149mAh. These batteries are ideal for energy-demanding devices such as wearables, portable (medical) devices, fitness trackers, and IoT applications, especially when space is limited.
All cell types have a cycle-life which is greater than 500 cycles, meaning they can be recharged and used again and again, making them a cost-effective and eco-friendly choice. Even at elevated temperature and high discharge currents these button cells show excellent performance.
The CoinPower A4X can be charged with different 3 charging rates: standard, fast and rapid. They are shipped in a state-of-charge of approximately 30% of their full capacity, which offers the best condition for long-term storage (shelf life exceeding 1 year) and a minimal self-discharge. To ensure complete traceability for every cell, each battery's lid and cup feature two data matrix codes.
