The 9-volt battery stores which form of electrical current?

Explanation:
A battery stores chemical energy and delivers electricity as direct current. The chemical reactions inside push electrons in one direction, so when connected to a circuit the current flows steadily in a single direction. Alternating current reverses direction periodically, which is not how a simple battery behaves. Pulsating current can occur in a DC system if the load varies, but the source itself remains DC. So a 9-volt battery provides direct current.
