OEM & ODM Baby Products Manufacturing

Our wide temperature lithium battery is a high-performance 18650 cylindrical lithium-ion cell engineered to deliver reliable power across an extreme temperature range, with a discharge capability spanning from -40°C to 85°C. Featuring a nominal voltage of 3.7V and a robust 2900mAh capacity, this wide temperature lithium battery maintains consistent performance in both frigid subzero environments and scorching high-temperature conditions, making it the ultimate power solution for equipment operating in diverse, harsh climates. Unlike standard lithium batteries that suffer capacity loss or failure in extreme temperatures, this cell uses a specialized electrolyte and material formulation to preserve ion conductivity and voltage stability, ensuring uninterrupted operation in the most demanding applications.
Designed in a standard 18650 form factor, this wide temperature lithium battery offers universal compatibility with a wide range of industrial devices, IoT sensors, outdoor electronics, and portable equipment. Its exceptional temperature resilience eliminates the need for thermal management systems in many applications, reducing design complexity and operational costs. Whether powering remote monitoring sensors in Arctic regions, industrial machinery in desert environments, or IoT devices in extreme climate zones, this wide temperature lithium battery provides the durability, safety, and long cycle life required for continuous, reliable operation across global temperature extremes.
