Alber CTL-400 Cellcorder Battery Tester

CellCorder battery tester

Accurate data in a fraction of normal test time

The intelligent, lightweight CellCorder cell resistance tester displays and records cell float voltage, internal cell resistance, and inter-cell connection resistance. Using a compatible hydrometer such as our CTL-200 Hydrostik Digital Data logging Hydrometer / Thermometer, you may automatically transfer data, such as specific gravity and temperature, using the on-board infrared port.

Use the CellCorder on a single cell or multi cell modules. Data is stored using a memory card that allows virtually an unlimited amount of data storage. The memory card, IR port, or internal modem transfer readings to a PC for analysis and advanced report generation via the supplied software.

The high contrast, 128 x 64 pixel, backlit graphical display shows menus and test results. A fully charged CellCorder can test for up to seven hours, and isolated operation helps ensure safety and makes the CellCorder easy to move around. Recharge power is supplied by a wall plug adapter.

Low cost The CellCorder replaces three instruments that individually cost as much as or more than this one instrument. Significant savings result from taking more readings in less time and analysing data more rapidly.

Multi cell capability The CellCorder provides readings on either single cells or Multi cell modules.

Reliable readings The CellCorder displays superior performance even in high noise environments - without the need to disconnect the battery from service. The instrument uses up to a 60 amp DC load (on 2V cells) to calculate internal cell resistance and inter-cell resistance. Circuitry rejects the 50Hz/60Hz ripple often troublesome to AC-based impedance and conductance meters.

System Measurements

  • Float Voltage Readings
  • NiCads to Multicell Modules (16V)
  • Internal Cell Resistance Measurement
  • Internal Resistance Connection
  • Intertier Resistance Connection

Battery Analysis Software

  • Full featured software easily identifies problem cells.
  • Built in report generator creates tabular or graphical reports.
  • Stores all historical data for trending and analysis as well as for warranty purposes and audits.
  • Import temperature and specific gravity readings into the BAS software for trending and analysis..

System Advantages and Features

  • Reliable readings even in the noisiest environments.
  • USB Flash drive for easy data transfer and storage.
  • Multiple test lead options and connections for all battery types.
  • Optional battery harness assembly increases efficiency and safety..


The CRT-400 Comes Supplied With:

  • Memory Stick
  • USB port memory card reader
  • *Resistance test leads 1100-221 or 1100-231 (Please see purchasing options)
  • Voltage test leads 1100-222
  • Carrying case
  • AC charger
  • Data trending and analysis software

*Included lead Sets

Included in the purchase price are either 1100-221 Standard Leads or 1100-231 Combined Leads. The 1100-221 Standard Leads will satisfy most requirements as the 3rd clamp is needed for those wishing to test the resistance of the intercell connection.
The voltage test leads 1100-222 come supplied additionally as standard.

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. Cell or module reading accuracy is to four full digits.

Internal Cell Resistance

The internal resistance of a cell can be determined by how that cell responds to a momentary load. The instantaneous voltage drop and load current applied are used to calculate the resistance. CellCorder algorithms make this measurement possible on cells floating on-line or off-line.

Inter Cell Resistance

The CellCorder measures the resistance between two cell terminals that are electrically connected. The measurement consists of the connector resistance and the contact resistance at the points of connection to the cell terminals.

Auto Ranging

The CellCorder automatically selects the correct voltage range, load resistor, and time for a test.
Data Extraction and Analysis After all testing is completed; the CellCorder can be connected via the internal modem, supplied Smart Card reader or infra red port to a PC or hand-held device. The data extraction program analyses test data and displays results in a bar graph or tabulated format. A test report may be printed or saved to a file. This file can be exported in an ASCII or comma-delimited format to allow off-the-shelf programs or supplied Battery Analysis trending software to generate customized reports.


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.

Orders requiring calibration 

Whilst we take the greatest care to get all orders dispatched and delivered to you in the stated time frame, orders received PM and requiring
calibration may on occasion miss dispatch that day, according to the complexity of the calibration. Be assured they will ship on the next dispatch
this in most cases should not add more than 24 hours to your delivery.

Bank/Public Holidays

Predicted delivery times are based on regular trading days Monday to Friday. Public holidays, bank holidays and weekends are outside the usual scope
of our dispatch and subject to activities/holidays of our carriers and therefore may incur additional days lead time to your order.
