FAQ for Portable Patient Monitor Batteries
A: We use a risk-management approach (FMEA), select only Tier-1 grade cells from top suppliers, and implement 100% end-of-line functional testing on every battery pack we produce.
A: Our factory is ISO 9001 certified, and our quality management system is designed with the principles of ISO 13485 in mind, including rigorous documentation, traceability, and risk management, making us a trusted supplier for medical device manufacturers.
A: Our intelligent BMS uses precise coulomb counting and communicates via SMBus or I2C to provide highly accurate State of Charge (SoC) data, typically with an error margin of less than 1-2%.
A: Yes, we can design the battery pack with a ruggedized enclosure and internal shock-absorbing materials to meet specific drop and shock resistance requirements.
A: Due to the extensive engineering and validation required, our MOQ for a new custom medical monitor battery typically starts at 50,000 to 100,000 units.
A: Yes, we have extensive experience designing hot-swappable battery packs, often incorporating additional circuitry to ensure a smooth power transition for the device.
A: We provide a comprehensive documentation package, including the battery’s specifications, all safety certifications (IEC 62133, UN38.3), and manufacturing quality data to support your technical file.
A: We typically design monitor batteries to retain over 80% capacity after 500-800 cycles, ensuring a long and reliable service life in a clinical setting.
A: Given the stringent design and documentation requirements, the lead time for the first batch of prototypes is typically 6-8 weeks.
A: Please provide your monitor’s power requirements (voltage, capacity, current), dimensional constraints, required certifications, communication protocol (if any), and any specific reliability targets.
