3.7V 4800mAh Ultra-Wide-Temperature Cylindrical Battery Cell (-70°C to 80°C) | ATOMFAIR

COMMERCIAL GRADE PRODUCTION

Product Overview
The ATOMFAIR® 3.7V 4800mAh ultra-wide-temperature cylindrical cell is engineered to deliver reliable discharge at -70°C and stable charging at -40°C, addressing the most demanding extreme-environment applications. With a 3.7 V nominal voltage, 4800 mAh rated capacity, and an energy density of ~180 Wh/kg, this platform demonstrates exceptional capacity retention and voltage stability across an ultra-broad temperature spectrum from -70°C to 80°C, representing one of the widest operating temperature ranges available in the industry. Featuring a maximum continuous discharge rate of 3C (14.4A) at ambient temperatures, along with 0.5C standard discharge capability, this cell ensures robust power delivery under extreme cold and high-temperature conditions. Cycle life validation confirms ≥1,000 cycles at 25°C, guaranteeing long-term operational reliability in the harshest environments. This commercial-grade solution is ideal for low-temperature lighting, outdoor surveillance, polar scientific expeditions, military border defense, cold chain logistics, humanoid robots, and portable energy storage applications where ultra-wide-temperature performance is non-negotiable.
