What does internal resistance mean in a battery?
Internal resistance can be thought of as a measure of the “quality” of a battery cell. A low internal resistance indicates that the battery cell is able to deliver a large current with minimal voltage drop, while a high internal resistance indicates that the battery cell is less able to deliver a large current and experiences a larger voltage drop.
