Low temperature battery for Military

Low temperature battery performance and features

Ampxell's low-temperature batteries maintain a capacity retention rate of over 90% in extremely cold conditions below -20℃. They deliver high-current discharge at up to 1.2C, making them ideal for military applications that require durability and reliability, with a lifespan exceeding 300 cycles.

Compared to standard batteries, Ampxell's low-temperature batteries utilize a specialized electrolyte, allowing them to operate in cold environments without the need for excessive replacement batteries, saving space in military vehicles. Standard batteries are notoriously unreliable in subzero temperatures—they can fail within minutes, leading to equipment shutdowns or mission failure. Ampxell's batteries eliminate such risks, ensuring consistent performance and reliability for military operations in extreme climates.
