EnerSys’ ABSL batteries used in space shuttle Endeavour mission spacewalks

LONGMONT, CO., June 6, 2011 -- EnerSys (NYSE: ENS), the global leader in stored energy solutions for industrial applications, announces that its recently acquired ABSL Space Products (ABSL) business provided a key component for the most recent astronaut spacewalks. ABSL batteries powered the Extravehicular Mobility Unit (EMU) during Extra Vehicular Activity (EVA) or spacewalks during the docking of the shuttle Endeavour shortly after Endeavour’s May 16, 2011 launch.

Four of ABSL’s high energy density Lithium-Ion (Li-Ion) long life battery assemblies were delivered to the International Space Station (ISS) by the space shuttle Discovery on February 24, 2011, in preparation of the most recent spacewalks. Four successful spacewalks were conducted, with one EMU per spacewalk powered by ABSL’s Li-Ion battery. The ABSL batteries supplied all the power needed to support functionality of the EMU.

ABSL’s battery assemblies replaced older silver zinc battery technology that had been previously used in the EMUs. ABSL’s high energy density batteries approach >190Wh/kg at cell-level, more than double that of the older silver zinc batteries, thus improving performance.

Battery power sources for manned space missions require a high priority on safety. 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 not compromised.

ABSL was the first battery manufacturer to qualify Li-Ion cells for space flight more than a decade ago and was the first to deliver a Li-Ion battery to orbit. ABSL continues with this tradition of battery heritage, innovation and product delivery by once again being the first to provide man-rated Li-Ion high energy density batteries to the ISS. ABSL designs, manufactures, and tests all of its batteries for the US market from its Longmont, Colorado facility. Additionally, ABSL Serves the European market through its facility in Oxfordshire, UK.

Space Shuttle Endeavour Sails To Home Port For Final Time

CAPE CANAVERAL, Fla. -- Space shuttle Endeavour and its six-astronaut crew sailed home for the final time, ending a 16-day journey of more than 6.5 million miles with a landing at 2:34 a.m. EDT on Wednesday at NASA's Kennedy Space Center in Florida.

Mark Kelly commanded the flight and was joined by Pilot Greg H. Johnson and Mission Specialists Mike Fincke, Drew Feustel, Greg Chamitoff and the European Space Agency's Roberto Vittori. Endeavour delivered the Alpha Magnetic Spectrometer-2 (AMS), beginning a scientific voyage of discovery to our solar system and beyond from the International Space Station. By measuring cosmic rays, AMS is designed to help researchers understand the origin of the universe and search for evidence of dark matter, strange matter and antimatter. Endeavour also delivered the Express Logistics Carrier-3, a platform carrying spare parts that will sustain space station operations once the shuttles are retired from service. The astronauts performed four spacewalks to maintain station systems and install new components.

These were the last scheduled spacewalks by shuttle crew members and brought the final number of shuttle excursions to 164. During 159 spacewalks for assembly and maintenance of the space station, astronauts and cosmonauts have spent a total of 1,002 hours and 37 minutes outside.
