• Client: MedTech Berlin GmbH (Pseudonym for a leading German medical electronics developer)

• Objective: Source a micro-scale, lightweight power solution with stable discharge to support continuous Bluetooth data transmission in a post-operative health monitor.

• Solution: The VATS 3.7V 270mAh 10280 Cylindrical Li-ion Battery Cell equipped with customized PCB protection.

• Results: Seamless integration into an 11mm hardware chassis, 14-hour continuous runtime achieved, and 100% compliance with strict EU safety directives.

In late 2025, a Berlin-based medical hardware manufacturer faced a severe engineering bottleneck during the final prototyping phase of an ergonomic, patient-worn biometric patch. The device required a direct current power source that could comfortably fit within an ultra-slim, cylindrical enclosure while sustaining a 3A maximum discharge current for sudden RF data bursts.

Standard button cells lacked the current capabilities, while traditional lithium-polymer blocks disrupted the product's sleek, 11mm aerodynamic shape. The engineering team required a tier-1 manufacturer capable of providing a miniature cylindrical form factor without sacrificing electrochemical reliability or safety overhead.

The German enterprise turned to VATS Battery to evaluate their 10280 (11280) cylindrical Li-ion series. The cell immediately met the physical constraints of the project:

• Micro Dimensions: A strict 11mm x 28mm footprint matching the device's interior cavity.

• Minimal Mass: Weighing a mere 6g, it ensured the final medical patch remained completely imperceptible to patients during overnight monitoring.

Through the factory's flexible ODM services, VATS engineers collaborated closely with the client's R&D department to integrate a customized PCB protection circuit. Given the medical nature of the device, failure was not an option. The integrated circuit was calibrated to provide redundant hardware defenses against over-charge, over-discharge, short-circuits, and over-temperature faults, utilizing high-stability Lithium Cobalt Oxide (LCO) chemistry to completely prevent thermal runaway.

Additionally, VATS supported the qualification phase by dispatching free evaluation samples within 48 hours, allowing the client's laboratory to perform rigid lifecycle and standard 0.2C continuous working rate benchmarks prior to capital commitment.

The deployment of the VATS 10280 battery cell yielded exceptional operational metrics for the German client:

Logistics and manufacturer reliability played an equally vital role in the success of the launch. VATS maintained an agile manufacturing and logistics schedule, delivering the initial commercial batch of 5,000 pieces to the client’s facility in Germany within the promised 20-day production window, fully equipped with comprehensive compliance paperwork to bypass EU customs without delay. Backed by the standard 12-month factory warranty and remote diagnostic support, MedTech Berlin GmbH has officially solidified VATS as its primary strategic vendor for its next-generation wearable portfolio.
