Cellcorder® CRT-400 Cell Resistance Tester

Customer Alert - CRT-300 to CRT-400 Upgrade Opportunity!

For our valued customers who currently own CRT-300’s, unfortunately, support for this product will be discontinued soon. However, to thank you for your loyalty, we are announcing a new Trade-In/Trade-Up program. In the past, we’ve offered an attractive discount on our new CRT-400, Cell Resistance Tester when you traded in your old CLC units. This discount will continue, but now the same offer is being extended to any CRT-300 customer that upgrades to a CRT-400. Please contact sales@alber.com or your sales rep please for further details. We appreciate your business and look forward to serving you.

The CRT-400, Alber's handheld Cellcorder utilizes the well-proven and patented DC Resistance Test to eliminate the guesswork when trying to identify a failing battery.

● Designed specifically to comply with IEEE Recommended Practices for Battery Maintenance and


● DC Resistance Test proactively identifies failing batteries.

● Designed for use in all industries.

What's New in the CRT-400

The Cellcorder CRT-400 is Alber's newest handheld cell voltage and resistance tester. This exciting addition to Alber's test, diagnostic and trending products measures and records cell float voltage, internal cell resistance, and intercell connection resistance.

Another exciting feature is a new USB port and Flash drive that allows quick transfer of data files to a computer. Using the Alber Battery Analysis Software, test results can be displayed and analyzed to determine battery state of health. The Flash drive also doubles as an interim storage device until test data is saved permanently.

Other features include a graphical reflective LCD display for better contrast, and new cables and clamps.

Accurate Data in a Fraction of Normal Test Time

The Cellcorder cell resistance tester displays and records cell float voltage, internal cell resistance, and intercell connection resistance. A compatible hydrometer lets you transfer specific gravity and temperature data using the IR port.

Use the Cellcorder on a single cell or multicell modules. The Flash drive allows virtually unlimited data storage. Use the Flash drive or IR port to transfer readings to a PC for analysis and report generation.

The high contrast, 128 x 64 pixel, backlit graphical display shows menus and test results. A fully charged Cellcorder can test for seven hours, and isolated operation helps ensure safety and makes the Cellcorder easy to move around.

Cellcorder Advantages

Low Cost - The Alber Cellcorder replaces three instruments that individually cost more than this one. Significant savings also result from taking more readings in less time and analyzing data faster.

Multicell Capability - The Cellcorder reads either single cells or multicell modules.

Reliable Readings - The Cellcorder performs even in high noise environments - without the need to disconnect the battery from service. Up to a 60 amp DC load (on 2V cells) is used to calculate internal cell resistance and intercell resistance. Circuitry rejects the 50Hz/60Hz ripple often troublesome to AC-based impedance and conductance meters.

The Cellcorder CRT-400 comes with a 256M Flash drive, resistance and voltage test leads, carrying case, AC charger, and data trending and analysis software. An optional printer is available.

System Features

Float Voltage Readings - The Cellcorder measures the voltage applied during full float operation. The voltage range covers all cells or modules up to 20 volts, with accuracy to four full digits.

Internal Cell Resistance - Using a patented process, the Cellcorder applies a momentary load and calculates internal cell resistance by determining instantaneous voltage drop and load current. Algorithms make this measurement possible on cells floating on-line or off-line.

Intercell Resistance - The Cellcorder measures the resistance between two electrically connected cell terminals. The measurement consists of connector resistance and contact resistance at the points of connection to the cell terminals.

Auto Ranging - The Cellcorder automatically selects the correct voltage range, load resistor, and test time.

Data Extraction and Analysis - After testing, transfer data to the PC via Flash drive or IR interface. Trending software analyzes test data, displays results in graph or tabulated formats, and saves and prints reports. You may export reports in ASCII, Excel® or comma-delimited format so other programs can generate customized reports.
