Spacecraft Battery
An electrical energy store supporting spacecraft when generation is insufficient.
Why it matters
Stored energy helps a mission continue through changing illumination and power demands.
Technology / power systems
Overview
Batteries support eclipse periods, peak demands and some short-duration missions. They store energy rather than generate it from nothing. Thermal management and charge limits affect useful life and reliability.

How it works
Electrochemical reactions exchange energy with the electrical system. Charge-control electronics manage current and voltage while monitoring the battery's condition.
Why it matters
Stored energy helps a mission continue through changing illumination and power demands.
