Specifications

The Hioki Battery Tester Series is a family of instruments designed for measuring battery internal resistance and open-circuit voltage across cells, modules, and packs. The lineup covers acceptance and shipping inspection on production lines, maintenance diagnosis of installed batteries, and research and development applications, with models ranging from the benchtop BT356x and BT4560 instruments to the handheld BT3554-50/-51/-52.

Within battery manufacturing, the series is positioned for use after cell completion — including discharge aging, cell testing, module and pack testing, installation, and diagnosis and repurposing. The BT3554-50/-51/-52 handheld units are intended for diagnosing whether batteries embedded in UPS systems or other installed equipment have degraded. The BT4560, when paired with the IM3590 Chemical Impedance Analyzer or PW6001 Power Analyzer, supports R&D analysis of batteries and fuel cells, including frequency-sweep impedance measurement and equivalent-circuit analysis.

The Hioki Battery Tester Series spans a wide range of battery-test applications — from small cells for general-purpose high-speed sorting (3561/3561-01) through small packs up to 60 V (BT3561A), mid-sized packs up to 100 V (BT3562A), large packs up to 300 V (BT3563A), and extra-large packs up to 1000 V for xEV and ESS applications (BT3564). The BT3562-01 and BT3563-01 add GP-IB to the 100 V and 300 V capability tiers. The BT4560 is purpose-built for R&D applications on cells or packs up to 20 V with frequency-sweep impedance measurement, and the BT3554-50/-51/-52 handheld units serve large-scale UPS maintenance.

All models in the series use AC four-terminal or four-terminal-pair measurement methods to determine internal resistance, with measurement frequency at 1 kHz (BT356x and BT3554-5x) or a sweep range of 0.10 Hz to 1050 Hz on the BT4560. The voltage measurement capability scales with each model's intended battery-pack voltage tier.

Each new model below is its own dedicated product page with condition-matched pricing, accessory configuration, and warranty terms. Use the comparison table to identify the model that fits your voltage range, resistance range, and interface requirements, then click through to the individual page for the specific new unit available.

The primary differences within the family are rated input voltage, resistance-range coverage, and interface options. Voltage ranges step from ±22 V (3561/3561-01) to ±60 V (BT3561A), ±100 V (BT3562A/BT3562-01), ±300 V (BT3563A/BT3563-01), and ±1000 V (BT3564). The 3561 and 3561-01 do not include the 3 mΩ or 30 mΩ resistance ranges; the BT3561A adds 30 mΩ; the BT3562A and higher models add both 3 mΩ and 30 mΩ at 100 mA measurement current. The BT4560 uses a different architecture entirely — four-terminal-pair measurement with frequency-sweep impedance and lower voltage input (±5 V DC standard), targeted at low-impedance measurement on individual cells.

Interface differentiation also separates the family. LAN is standard on the BT3561A, BT3562A, and BT3563A. The 3561-01, BT3562-01, BT3563-01 include GP-IB instead of LAN. The base 3561 and BT3564 do not include LAN or USB.

Model Rated Input Voltage Resistance Ranges Measurement Frequency
3561 ±22 V DC 300 mΩ, 3 Ω 1 kHz ±0.2 Hz
3561-01 ±22 V DC 300 mΩ, 3 Ω 1 kHz ±0.2 Hz
BT3561A ±60 V DC 30 mΩ to 3 kΩ 1 kHz ±0.2 Hz
BT3562A ±100 V DC 3 mΩ to 3 kΩ 1 kHz ±0.2 Hz

Product Core & Specifications

Important: When multiple battery testers operate in close proximity, induction fields from the measurement currents can interfere with each other and cause measurement errors. Use the measurement current pulse output function (available on BT3561A and higher) to allow the measurement current to flow only during measurement, enabling alternating measurements between instruments.
Important: Bluetooth functionality and wireless adapter compatibility on BT3554-50/-51/-52 requires the Z3210 Wireless Adapter (sold separately).
Important: BT3564 maximum input voltage is 1000 V DC; the optional L2110 probe is designed specifically for the BT3564 with 1000 V withstand voltage for safely testing high-voltage battery packs.
Important: BT4560 special specifications support extended frequency (up to 10 kHz) and higher rated input voltages (up to ±20 V DC). Standard specification is 0.10 Hz to 1050 Hz at ±5 V DC.
Important: BT3564-FC is a special-specifications variant intended for fuel cell (FC) measurement applications.
Important: Some measurement leads/probes listed in the compatibility chart are not subject to accuracy guarantee when used on certain instruments; refer to the chart footnotes for details.
Important: When using a measurement current of 10 mA or less, the system may be susceptible to external noise — caution is required.
Important: BT4560 4-terminal-pair design: wiring placement has a significant effect on measured values when not using a 4-terminal-pair connection.
