FAQ for Digital Pens & Smart Notepads Batteries
A: We are constantly pushing the boundaries of miniaturization. We can produce pin-type cells with diameters as small as [e.g., 4mm] and lengths as short as [e.g., 15mm]. The final dimensions are a trade-off with the required capacity.
A: We use a combination of a high-energy-density cell and a specialized low self-discharge chemistry. This, combined with your device’s optimized low-power Bluetooth and standby modes, enables very long runtimes.
A: Due to the highly specialized and automated manufacturing process for micro-batteries, our MOQ for a new custom design typically starts at 20,000 to 50,000 units.
A: Yes. Our batteries are designed to provide the stable, clean power required by the sensitive electronics that manage pressure levels, tilt detection, and Bluetooth communication.
A: Our digital pen batteries are designed for a long product life, typically specified to retain high capacity after 300-500+ charge cycles.
A: Given the precision required, the lead time for the first batch of functional prototypes is generally 6-8 weeks after design finalization.
A: We can design the battery to be compatible with various charging methods, including discreet pogo pins, magnetic connectors, or even wireless charging integrated into the pen or a case.
A: Typically only a few grams. We work meticulously to minimize weight to ensure the pen’s balance and ergonomics are not compromised.
A: Absolutely. We manage the entire certification process to ensure your product’s battery meets all required standards for your target markets, including CE, UL, IEC, and UN38.3.
A: Please provide the maximum available space (diameter and length for pin-type; T x W x L for flat cells), required minimum runtime (hours) or capacity (mAh), voltage (3.7V), and your estimated annual volume.
