Ultra Life Batteries

What Ultra Life Batteries does

Ultralife Corporation (NASDAQ: ULBI) is a U.S.-based designer and manufacturer of mission-critical battery and RF power solutions, founded in 1990 and headquartered in Newark, NY. The company operates across two core product categories — Battery & Energy Products (non-rechargeable lithium cells, rechargeable Li-ion and NiCd packs, thin-cell batteries as thin as 1.1mm, and conformal wearable batteries) and Communications Systems (RF amplifiers from 20W to 75W, ruggedized HPE EL8000 server cases, satellite communications, and military-grade power supplies). Its technology spans lithium thionyl chloride (Li-SOCl2), lithium manganese dioxide, NiCd, and proprietary thin-film cell chemistries engineered for extreme environments spanning arctic to desert conditions and 6,000m ocean depths.

The company employs 501–1,000 people across nine global Centers of Excellence in North America, Europe, and Asia, and reports ISO 9001:2015 and ISO 13485:2016 certifications enabling defense, medical, industrial, and oil & gas market participation. It monetizes primarily through quote-based B2B hardware sales to defense primes, government agencies, medical OEMs, and industrial OEMs, supplemented by solutions-engineering services for custom battery and power systems designed for 10–15+ year lifecycles. GTM is dominated by enterprise field sales with embedded solutions engineering and direct OEM partnerships, supported by an e-commerce storefront for standard products. Recent strategic activity includes the 2025 acquisitions of Excell Battery Group ($19M) and Electrochem Solutions, the 2026 X5-SuperLite product launch with Karta Healthcare, and a partnership with HPE for ruggedized tactical server solutions. Quarterly revenue in 2025 ranged from $43.4M (Q3) to $48.5M (Q4), implying an annual run-rate near $185–195M, with a record $115.1M order backlog at Q1 2026.
