About Ultralife's Excell Battery Group

Empowering global OEMs with 40+ years of engineered portable power, premium cell integration, and military-grade battery reliability.

Pioneering Custom Battery Solutions for Mission-Critical Applications

Formed in 1985, Excell Battery Group has established itself over four decades as a trusted partner for OEM engineering teams requiring reliable power under demanding environmental conditions. From deep-well oil & gas exploration to portable medical devices and hazardous-location industrial monitoring, our custom battery packs power industries where failure is not an option.

In December 2021, Excell Battery was acquired by Ultralife Corporation — a NASDAQ-listed global provider of critical power solutions and communication systems. This strategic milestone combines Excell’s specialized engineering agility with Ultralife’s extensive international manufacturing infrastructure and supply chain resilience.

With multi-facility operations strategically located across North America — including Surrey (Vancouver), Calgary, and Houston — Excell Battery serves global enterprise procurement teams with end-to-end support spanning cell selection, custom BMS design, UN 38.3 compliance testing, and full lifecycle production.
