In the United States, the unit of measure of radioactivity is the curie. Activity: How much radiation is present?
As the battery is discharged, or used, the acid concentration decreases and becomes weaker (dilute) until the battery cannot produce an electrical current. This makes it possible to tell the state of charge by seeing how weak the electrolyte is. A hydrometer is used to measure the strength of the electrolyte. Both negative and
