Various functions allow you to measure initial voltage, voltage drops and voltage drop rates (e.g. mV/day, mV/hour). The included judgment function makes it easy to determine which battery cell is experiencing aging defects.
The voltage of a battery is a fundamental characteristic of a battery, which is determined by the chemical reactions in the battery, the concentrations of the battery components, and the polarization of the battery. The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage.
The consistency of voltage in lithium batteries refers to the ability of individual cells within the same batch or system to maintain the same terminal voltage under identical conditions. Voltage consistency is crucial for the overall performance, lifespan, and safety of lithium battery packs.
During Discharge: As a battery discharges, its voltage gradually decreases. For example, a lithium-ion battery will drop from around 4.2V (fully charged) down to 3.7V, then further to 3.0V (cut-off voltage), after which the device will stop working. During Charging: When charging, the battery voltage increases.
Such defects can be discovered with short aging times using a high-precision, high-resolution voltmeter that allows to detect even slight voltage drops. Defective battery cells with large self-discharge are identified by an aging process. If a slight drop in voltage is captured, it is possible to rapidly detect a defective cell.
Various functions allow you to measure initial voltage, voltage drops and voltage drop rates (e.g. mV/day, mV/hour). The included judgment function makes it easy to determine which battery cell is experiencing aging defects.
Selecting the Right Tool: A multimeter is the most common tool for measuring battery voltage. Ensure it's set to measure voltage (volts). Preparing the Battery: Ensure the battery is clean and the terminals are accessible. For rechargeable batteries, ensure they are adequately charged.
