READ MORE: Astronauts kicked off the first of five spacewalks to replace old batteries at the International Space Station on Sunday.

Christina Koch and Andrew Morgan had to remove a pair of old batteries and install a new one delivered just a week ago. These new lithium-ion batteries are so powerful that only one is needed for every two old ones, which are original to the orbiting lab.

The 400-pound (180-kilogram) batteries — half the size of a refrigerator — are part of the space station's solar power network. Astronauts have been upgrading them since 2017. They're halfway done. The old batteries are 10 years old; the new ones are expected to last until the end of the space station's life.
