EnerSys' ABSL Batteries Successfully Delivered to the International Space Station

READING, Pa., March 8, 2011 /PRNewswire/ -- EnerSys (NYSE: ENS), the global leader in stored energy solutions for industrial applications, announced that its recently acquired ABSL Space Products (ABSL) business had its batteries successfully delivered to the International Space Station (ISS).

ABSL was the first space flight battery manufacturer to qualify Lithium-Ion (Li-Ion) cells for space flight more than a decade ago and was the first to orbit a Li-Ion battery. Continuing this tradition of battery heritage, innovation and product delivery, ABSL completed four high energy density Li-Ion long life battery assemblies that were completely designed, manufactured, and tested at its Longmont Colorado facility. The battery assemblies were delivered to NASA Johnson Space Center for the Extravehicular Mobility Unit (EMU) Program in 2010. On February 24, 2011, the four battery assemblies were launched aboard shuttle Discovery on its last mission to rendezvous with the ISS, the second space launch of ABSL Colorado-built battery hardware. Earlier this year, ABSL delivered a battery to an undisclosed client for a space flight.

The high energy density Li-Ion long life battery assemblies, >190Wh/kg at cell-level, will replace older silver zinc battery technology on the EMU for spacewalks from the ISS. ABSL heritage and innovation played a fundamental role in meeting the technical challenges involved with the replacement of the existing older technology. Flexibility with battery configurations and ABSL's ability to customize solutions for NASA allowed the Li-Ion replacement batteries to operate within the existing space and electrical interfaces of the equipment. The energy density of ABSL's battery assemblies will more than double the present run times of the older silver zinc batteries, thus improving performance and increasing safety and reliability.

The battery assemblies are planned to be used for the first time for spacewalk activities in late April or early May 2011 during the STS-134 docked duration. Manned space missions such as these require battery power sources to be, above all, safe and ABSL's high performance batteries are designed with multiple levels of redundancy that can maintain functionality under various failure scenarios in order to ensure safety is never compromised.
