The battery cycle tester is used for battery charge/discharge testing (battery recycling testing) of lithium-ion batteries. In response to global environmental issues, energy problems, use of natural energy, miniaturization, and mobility of products, and rising expectations for electric vehicles, research and development of various types of
can be important in battery inspection, those of smell, feel, and hearing. A key to battery inspection is knowing what should be there and what it should look like. Then, if one sees, experiences or senses something different, they would know what could be an issue. Also, having the ability to know what caused the anomaly is important.

NI''s battery test systems have a built-in pre-charge circuit that provides a "soft start" to automatically match the voltage on the DC output to the battery voltage. Some bidirectional power supplies and some battery cyclers on the market don''t have the safety contactors, polarity checker, or pre-charge circuits built into their test systems.

A battery capacity test will consist of a controlled current discharge of the battery systems in order to determine the capacity at the rate determined by the load reserve time requirements or at the manufacturer’s claimed performance rate for a specified time.
Measure the electrolyte temperature of 10% or more of the battery cells. At least once per year, the quarterly inspection will be augmented as follows: In the case of a lead-antimony battery, measure and record specific gravity and electrolyte temperature of all cells.
The discharge current will be maintained within +/- 1% until the battery voltage measured at the battery terminals equals an average of the required low voltage limit. (For example, 60 cells x 1.75V = 105VDC battery terminal voltage) A battery capacity test system will be used to conduct the discharge test.
In the case of a lead-antimony battery, measure and record the specific gravity of 10% of the cells and float charging current. For chemistries other than lead-antimony and where float current is not used to monitor the state of charge, measure and record the specific gravity 10% or more of the battery cells.
