What’s the required certificate for Medical Device Battery?

We have everything you need to know about medical device batteries.

Our team is experienced in the medical battery field and can assist you in obtaining the necessary certifications and compliance documentation.

IEC 60601-1

IEC 60601-1 is a fundamental standard for medical devices and medical batteries.

IEC 62133

Safety requirements for secondary cells, lithium-ion and lithium-polymer batteries used in portable devices.

FDA Approval (for US market)

Medical device batteries used in devices regulated by the FDA must comply with FDA requirements for safety, reliability, and performance.

CE Marking (for EU market)

The CE mark indicates conformity with health, safety, and environmental protection standards for products sold within the European Economic Area (EEA).

UN/DOT 38.3

Li-ion medical device batteries must comply with UN/DOT 38.3 for safe transport by air, sea, or ground, in addition to their focus on transportation safety.

Let’s Talk About Your Battery Needs!

We specialize in designing and assembling custom lithium-ion battery packs, including 18650 and 21700 batteries. We also offer LiFePO4 (Lithium Iron Phosphate) batteries for high-safety, long-lifespan applications. Whether you’re in the Light electric vehicle (LEV), solar energy, marine, Industrial Equipments, Medical Healthcare or consumer electronics industries, we can design the perfect battery solution for your needs.

Safety is our top priority. Every battery packs goes through 100% comprehensive testing to ensure it meets the highest standards for performance and safety. We use premium components from trusted brands and employ an automated production process to minimize human error, ensuring consistent quality across every order.  Our strict quality tests includes aging testing (capacity testing, charging and discharging testing), thermal cycling, overcharge protection, short-circuit testing, vibration testing and more. In addiction, we also integrate advanced Battery Management Systems (BMS) that monitor temperature, voltage, and current to prevent potential issues.

We offer fast and reliable delivery for both sample orders and bulk orders. Sample orders within 7 to 10 days. For large-scale orders of custom battery packs, we typically require 3 to 4 weeks for design and production, depending on the complexity and quantity of the order. We work closely with our clients to ensure we meet their deadlines.

Yes, we offer custom design services tailored to your specific requirements. Whether you’re building a solar energy storage system, light electric vehicle, underwater diving or marine application, our team will work with you to understand your needs and design a battery pack that fits your power, capacity, and space requirements perfectly.

We offer a standard 1-year warranty on all of our custom battery packs, covering any manufacturing defects. Additionally, our LiFePO4 batteries come with 5 years warranty and typically have a longer cycle life, meaning they will last longer than many traditional battery chemistries. For specific warranty terms, feel free to reach out and we’ll provide details based on your project.

Yes, all our lithium battery packs comply with international safety standards and are certified for use in various regions. We can help you get all the necessary certifications, like UL 2054, UL 2271, CE, IEC 62133, RoHS, and UN38.3 for transportation safety. We ensure that each battery pack meets or exceeds global regulatory requirements to ensure safety and compliance.

Extreme temperatures can have a significant impact on battery performance and lifespan. At Saphiion, we offer customized high and low-temperature lithium battery solutions designed to perform reliably from -40°C to 85°C. For applications where your battery is exposed to severe conditions (e.g., outdoor equipment, GPS trackers to industrial machinery in extreme climates), we recommend using our temperature-resistant battery packs. Additionally, ensuring proper insulation and avoiding extreme overcharging or discharging can help extend the life of your battery.
