FAQ for Handheld Diagnostic Instrument Batteries
A: Our primary strategy is maximizing energy density (mAh per cubic centimeter). We use the most advanced cell materials and custom-shape the battery to fill all available internal space, ensuring the longest possible runtime.
A: Yes, we can design the battery pack with high-discharge-rate (High-C) cells and a robust BMS to handle the high, instantaneous power pulses required by ultrasound transducers and other demanding components.
A: Due to the engineering and validation involved, our MOQ for a new custom medical diagnostic battery typically starts at 50,000 to 100,000 units.
A: Very accurate. We integrate intelligent BMS with fuel gauge ICs that use coulomb counting and communicate via SMBus or I2C. This provides the host device with precise State of Charge (SoC) data, which is critical in a clinical setting.
A: At a minimum, UN38.3 for transportation and IEC 62133 for international safety compliance are required. Depending on your target market, UL or other specific certifications may also be necessary. We manage this entire process for you.
A: Yes, for devices that require continuous operation, we can design a hot-swappable battery system, allowing users to change batteries without powering down the instrument.
A: We use robust materials for the battery pack housing and high-mating-cycle connectors. Our designs are also validated through drop, shock, and vibration testing to ensure they can withstand the rigors of a clinical environment.
A: The lead time for the first batch of prototypes for a new diagnostic device battery is typically 6-8 weeks after design finalization.
A: We provide a comprehensive documentation package, including detailed specifications, manufacturing quality data, and all safety certifications (IEC 62133, UN38.3, etc.) to support your technical file for FDA or CE submissions.
A: Please provide your device’s dimensional constraints (a 3D model is ideal), power requirements (voltage, capacity, peak/continuous current), required certifications, and your estimated annual volume.
