SERUI Battery: Your Trusted Partner for Ultra Thin Battery Solutions – From Standard Models to Custom Designs

In the fast-paced world of product development, miniaturization is no longer a trend—it’s a necessity. Whether you’re engineering wearable tech, compact medical devices, or slim IoT sensors, the demand for ultra thin battery solutions that balance power, size, and reliability has never been higher. At www.serui-battery.com, we specialize in delivering high-performance thin batteries tailored to your unique needs, including thin LiMNO2 battery (non-rechargeable) and Thin Lipo battery (rechargeable) options that meet the most stringent specifications for voltage, capacity, and dimensions.
When a global product developer recently reached out to us with a request for thin battery solutions—seeking Non-rechargeable thin battery and rechargeable options with nominal voltages of 3.0V or 3.7V, capacities from 40mAh to 500mAh, and target dimensions of approximately 40mm × 60mm × 1mm—we were ready to deliver. Their inquiry is a perfect example of how SERUI Battery bridges the gap between off-the-shelf convenience and custom precision, ensuring our clients get the exact power solution they need to bring their innovations to life.
Why Choose SERUI’s Ultra Thin Battery Lineup?
At SERUI Battery, we understand that every product development project has unique requirements. Our ultra thin battery portfolio is designed to offer flexibility, performance, and peace of mind—whether you opt for a standard model or a custom-designed solution. Here’s why industry leaders trust us for their thin battery needs:
1. Comprehensive Range of Thin LiMNO2 Battery (Non-Rechargeable)
For applications that demand long-lasting, maintenance-free power, our thin LiMNO2 battery series (a top-tier Non-rechargeable thin battery option) is unmatched. LiMNO2 chemistry delivers stable voltage output, excellent shelf life, and reliable performance in compact form factors—making it ideal for devices that don’t require recharging.
In response to our client’s inquiry, we recommended two of our most popular standard thin LiMNO2 battery models:
But we didn’t stop there. The client’s target dimension of 40mm × 60mm × 1mm required a custom solution—and we were ready to deliver. Our engineering team confirmed that a Non-rechargeable thin battery with this exact size could be developed to deliver 500mAh capacity, tailored to their product’s specifications. While custom designs like this require a new mold, our streamlined development process ensures minimal lead times, so you can keep your project on track.
2. High-Performance Thin Lipo Battery (Rechargeable)
For products that benefit from rechargeability—such as wearables, portable gadgets, or reusable medical devices—our Thin Lipo battery (lithium-polymer) series offers exceptional energy density and flexibility. These ultra-slim rechargeable batteries are designed to fit tight spaces while delivering consistent power cycle after cycle.
To meet the client’s 3.7V rechargeable requirement, we proposed two of our proven Thin Lipo battery models:
What sets our Thin Lipo battery apart? Advanced lithium-polymer technology ensures low self-discharge, high cycle life, and superior safety—critical factors for consumer and industrial products alike.
3. Quality, Safety, and Environmental Compliance – Our Top Priorities
At www.serui-battery.com, quality, safety, and environmental protection are non-negotiable. Every ultra thin battery we produce—whether a standard thin LiMNO2 battery, a custom Non-rechargeable thin battery, or a high-performance Thin Lipo battery—undergoes rigorous testing to meet international standards. We adhere to ISO 9001 quality management systems, UN38.3 transport safety regulations, and RoHS environmental standards, ensuring our batteries are safe for use, reliable in performance, and kind to the planet.
For product developers, this means zero compromises: you get a thin battery that performs as promised, meets global compliance requirements, and protects your brand’s reputation for quality.
