Hioki BT3554 is a portable battery testers support the maintenance of UPS and storage batteries critical to the life support of all businesses. The Hioki BT3554 battery internal resistance tester sets the standard for assessing the deterioration and remaining life of UPS and other lead-acid batteries by giving a complete diagnosis via battery resistance testing. The specially designed L2020 Pin Type Lead further improves testing efficiency with an L-shaped tip that lets you reach deep into the battery racks to completely probe the terminals.

Accurately assess lead-acid battery deterioration using proprietary technology

The new Battery Tester BT3554-50 sets a new standard for UPS and lead-acid battery diagnostics. Since the battery’s internal resistance and voltage are measured using the impedance method, diagnostics can be performed while the battery is connected to its host device, without taking it offline. Proprietary noise reduction technology allows more accurate measurement, even in noisy environments.

Generating comparative judgments based on a lead-acid battery’s internal resistance and voltage

By using its comparator function to simultaneously measure the internal resistance and voltage of a lead-acid, nickel-cadmium, or nickel-hydride battery, the BT3554-50 can generate comparative judgments quantifying degradation of the cell based on user-specified threshold values.
Furthermore, voltage sign detection facilitates instantaneous determination of whether batteries have been connected properly in newly installed UPS systems.

Saving data easily just by placing the leads in contact with a battery’s terminals

The BT3554-50 auto-hold function automatically holds measured values once they stabilize. The instrument’s auto-memory function, which automatically stores measured values resulting from the auto-hold function in its internal memory, further streamlines work tasks.

New leads for more convenient measurement in distribution panels and other confined locations

The Pin Type Lead L2020 with L-shaped tips is available as a new option. The design significantly improves ease of use when inspecting batteries installed in confined locations.

Applications: Manage other UPS inspection data together

GENNECT can serve as a central repository for managing data from Hioki clamp meters and other instruments.
Example: UPS inspection

1. UPS system ACV measurement (CM4372, CM4374)


2. DCV measurement (CM4372, CM4374)


3. AC/DC current measurement (CM4372, CM4374)


4. Ripple current measurement (CM4002)


5. Battery degradation diagnostics (BT3554-50)


6. Measurement site photograph

Wall and shoulder straps let you work with both hands

If you’re measuring a number of batteries in a large area, use the included shoulder strap to carry the instrument with you while making measurements. Or if there are numerous batteries at a single location, use the Magnetic Strap Z5020 (sold separately) to hang the instrument on the wall while you work.

Key Features

• Battery measurement can be performed while the battery is connected to its host device, without taking it offline
• Measure and save data in as fast as 2 seconds, a 60% improvement from the legacy 3554
• Instantaneously diagnose battery degradation (PASS, WARNING, FAIL) by measuring internal resistance and voltage (*1)
• Noise reduction technology improves noise resistance
• Screen and audio (*2) guidance simplifies measurement
• Measurement data is linked to site information and saved, reducing management man-hours
• Easily transfer measurement data to your smartphone or tablet by using our free app GENNECT Cross (*3) or to an Excel® file. (Wireless Adapter Z3210 is necessary)
• New protector delivers better ergonomic hold and durability in the field.

*1:The thresholds for determining the pass/fail condition of a battery depends on the specifications and standards of the battery manufacturer, battery type, capacity, etc. It is important and necessary to always conduct battery testing against the internal resistance and terminal voltage of a new or reference battery. In some cases, it may be difficult to determine the deterioration state of traditional open type (liquid) lead-acid or alkaline batteries which demonstrate smaller changes in internal resistance than sealed lead acid batteries.

*2:Audio generated by Bluetooth®-connected device.

*3:Data can be downloaded to tablets and smartphones using Hioki’s dedicated free app "GENNECT Cross," available from the Google Play or App Store. (when using the Z3210)

Wireless support - Wireless communication capability for even greater convenience

Compatible with Wireless Adapter Z3210 (optional). It transfers measurements to your smartphone or tablet and allows you to quickly create reports with field photos and drawings.

Enjoy measurement guidance and easy data management functionality with the latest software

When the BT3554-50 is paired with a dedicated mobile app (GENNECT Cross), the mobile device will provide audio guidance announcing the next battery number to be measured. This feature helps prevent erroneous measurements. You can also set up measurement locations informations and battery numbers in advance to create profiles to which measurement data and diagnostic results will be linked. This capability simplifies data management, even when performing diagnostic work on large numbers of batteries.

Get Results in as Fast as 2 Seconds

Simply touch the test leads to the battery terminals to easily capture battery condition data with the Hioki BT3554-50 Battery Tester. Automatically save measurements results using the auto-hold or auto-memory function in just 2 seconds, a 60% reduction from the legacy product.

How to use Battery Testers: Observing Measurement Results Captured Wirelessly on a Mobile Device

Measured values captured by the Hioki BT3554-50 Battery Tester with Bluetooth wireless technology can be displayed and saved onto a mobile device wirelessly. (When using the Wireless Adapter Z3210) The results can also be used to create automatic reports. Simply install the free GENNECT Cross app onto your mobile device and connect to the Hioki BT3554-50. Reports created on your mobile device can even be e-mailed to the office to further increase work efficiency. Data uploaded by the Gennect Cross app can also be loaded into a PC to view the historical state of the specified battery as a graph.
