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.
Mastering Battery Load Tests: A Complete Guide
Part 3. Types of battery load tests. Here are some common types of load tests: Constant Current Load Test: This test applies a constant current load to the battery and measures its voltage response over time. It helps assess the battery''s capacity and performance under sustained current draw.
Lead Acid Battery Voltage Chart: The Voltage Level Differences
During the bulk stage, the battery is charged at a high current rate until it reaches 80% to 90% of its capacity. The absorption stage then follows, where the battery is charged at a lower current rate until it reaches 100% capacity. Finally, during the float stage.
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

If you only have periodic voltage measurements and the load current is small, you can approximate the state of charge of the battery with a SOC-OCV (state of charge - open circuit voltage) graph. You can probably find this graph for whatever chemistry battery you have and find the SOC that corresponds to a given voltage.
