Steps: Insert the Battery: Place the fully charged lithium battery into the tester. Set Parameters: Set the tester to your battery's cut-off voltage (usually around 2.5V to 3.0V) and the charge/discharge current. Start the Test: Let the tester fully charge and discharge the battery. It will provide readings of voltage, current, and time.
For any type of battery technology, discharge testing it from its fully charged voltage down to its discharge voltage level, is the one true accurate measurement of its capacity and performance. For a small single battery, a discharge test is not to onerous.
To test self-discharge rate, follow these steps: Fully Charge the Battery: After charging, leave the battery unused and disconnected. Measure Voltage Over Time: After several days or weeks, recheck the voltage. A healthy lithium-ion battery 12V should lose only a minimal amount of charge when unused.
For a small single battery, a discharge test is not to onerous. For larger multi-cell battery banks that provide emergency power to critical infrastructure, it can be quite a burden, hence the drive to find other methods to determine the state of health of a battery bank.
