Lithium Batteries Replace Alkalines on Space Shuttle

According to Energizer, NASA engineers have used the battery maker’s e2 Lithium batteries to replace all standard alkaline batteries on the latest Space Shuttle Discovery. Discovery's flight, a mission to deliver equipment and supplies to the International Space Station, launched on July 26 with Energizer e2 Lithium batteries powering the onboard cameras and video-recorders.

According to Energizer, the e2 Lithium batteries are the world's longest lasting AA and AAA batteries in high-tech devices, weigh one-third less than traditional alkaline batteries and can operate in conditions where alkaline batteries would fail, temperatures ranging from -40°F to 140°F. The weight factor is considered especially critical on space shuttle missions given that, in shuttle design, every pound requires an additional $10,000 in expense.

The difference in battery life may be less of an issue on shuttle missions, but may be significant in consumer applications. According to Energizer, the e2 Lithium batteries offer a shelf life of up to 15 years versus seven years for an alkaline battery.
