Battery Discharge Testing: Implementing NERC Standards …
To perform a type 1 test, first determine the initial current required, either by the maximum load the battery will see for the duty cycle or by the manufacturer''s one minute rate divided by the aging factor. For the remainder of the test, use the manufacturer''s published discharge rate for the time period specified by the
9V Battery Voltage Chart: A Comprehensive Guide
Therefore, the battery''s age can significantly impact its remaining voltage and overall performance. Load Characteristics: The type of load applied (resistive, inductive, or capacitive) and its consistency can affect the battery''s voltage. A steady, low-resistance load will draw a consistent current, leading to a predictable voltage drop.
