Use the Internal Resistance Tester to test the each battery block. Pay attention that the measurement probe should touch the battery terminals directly, not the screws.
For what it''s worth, lead acid capacity is not easy to predict. This is key: The capacity of a lead acid battery depends on the load. A new 100 Ah battery at 20H would give you indeed 5A for 20 hours (60Watt). But this is the kicker: If your actual load on the battery is 120 Watt or 10A you won''t get 10 hours.

Lead-acid batteries are highly sensitive to temperature. Testing should ideally be conducted at room temperature to ensure accurate results. Extremely high or low temperatures can skew the results of voltage, capacity, and resistance tests. To ensure optimal performance, it is recommended to perform battery testing at regular intervals.
Impedance Testing: Comprehensive Health Assessment Lead-acid batteries degrade over time due to several factors, including sulfation, temperature fluctuations, and improper maintenance. Testing these batteries at regular intervals allows us to detect potential problems early, ensuring longevity and optimal performance.
Capacity testing is a more thorough method of evaluating a battery's ability to deliver its rated energy. This test simulates real-world usage and is essential for determining whether a battery is still capable of performing its intended function.
A fully charged lead-acid battery should have a voltage of around 12.8 volts. If the voltage drops below 12.4 volts, the battery needs to be recharged. Internal resistance is also an important factor to consider. A battery with high internal resistance will have difficulty delivering power, which can result in poor performance.
To perform the load test, follow these steps: Charge the battery fully before testing. Connect the load tester to the battery terminals. Set the load tester to the appropriate load for the battery. Apply the load for 10 to 15 seconds. Record the voltage reading. Compare the voltage reading to the manufacturer's specifications.
