Li-CFX/MN02 Military Packs
High-energy military battery packs

- Non-rechargeable XX90-format military battery packs powered by Ultralife’s advanced Li-CFx/MnO₂ hybrid chemistry, delivering significantly higher energy density than legacy BA-5390 and BA-5590 batteries.
- Available in compact 16Ah (UB0031) and high-capacity 32Ah (UB0032) configurations, providing up to 480Wh of energy for military communications, targeting, surveillance, and portable electronic systems.
- Integrated 5-segment State-of-Charge Indicator helps maximize battery utilization, while the Complete Discharge Device (CDD) provides a visual indication when batteries are ready for disposal.
- Designed for harsh operating environments with lightweight construction, improved low-temperature performance, no voltage delay, and up to 12 years shelf life with 80% remaining capacity.
