Since building the first Lithium-ion (Li-ion) battery to power a satellite, technological breakthroughs from EnerSys® have extended satellite operational life and have lengthened the life of space missions to benefit our scientific communities.

When maintenance or replacement isn’t an option, reserve power is mission-critical for success. Typically called upon when solar power is unavailable, EnerSys® batteries supply power for platform and payload systems and are also essential prior to the deployment of any solar array apparatus. Whether a short-term repositioning energy requirement or high current demand such as a pyrotechnic system actuation, our batteries stand ready to meet the challenges of space flight with advanced high voltage, long-life Li-ion solutions.




Our design engineers understand how critical batteries are to the success of every mission. We manufacture spacecraft batteries that supply mission-critical power for platform and payload systems.

EnerSys helps power Parker Solar Probe

The Parker Solar Probe spacecraft will travel at 125 miles per second as it flies through the sun’s atmosphere as close as 3.8 million miles to our star’s surface. As it withstands temperatures of up to 2,500°F, the probe will capture detailed measurements of the sun from space.
