Our Company

From our start in primary batteries, we shifted our focus to secondary or rechargeable batteries in the 1980s. When Operation Desert Storm demonstrated that rechargeables were the answer to meeting the power needs of troops on the ground while reducing their logistics load, we helped lead the way in nickel-cadmium rechargeables.

From those early secondary batteries to today's lithium-ion systems, we've succeeded in engineering solutions that deliver the staying power of primary cell batteries with the extreme reusability demanded by today's military. We continue to innovate with lithium polymer chemistries and solutions tailored for use with solar cells and fuel cells.
