Achieve Long Service Life Battery Modules by
Measuring Reaction Resistance
Hioki benchtop battery testers support simultaneous high-speed measurement
in the ever-expanding production lines of increasingly larger lithium-ion
low resistance batteries. The BT4560 battery impedance tester measures the
impedance of lithium-ion batteries using the low-frequency AC-IR measurement
method without charging and discharging the battery, substantially reducing
the time needed to inspect the internal resistance of battery cells.

Key Features

• Low-frequency AC-IR measurement* : Measure the reaction resistance of a battery
*The BT4560 ensures battery cell quality by measuring internal impedance at a low frequency of 1 Hz or below
• Extremely reliable measurements for low-impedance batteries
*The BT4560 uses a testing current of 1.5 A at the 3mΩ range, which improves the S/N ratio
• Circuit configuration highly tolerant of contact and wire resistance to provide stable measurements
• Voltage measurement function equivalent to 6-digit DMM (± 0.0035% rdg.)
