Importance of Precision
This plot illustrates the difference between an Arbin battery tester and another leading manufacturer. The first of the two distinct dips in the plot may have been missed using inferior test equipment. While many companies try to sell the same legacy equipment for over a decade, Arbin has been hard at work improving our designs to meet future industry demands. We learned a lot during our three year ARPA-E project to develop high-current high-precision testers, and have implemented this new technology in our LBT, RBT-Cell, and HPS test equipment series. The HPS ultra-high precision systems represent our premium product, but LBT is superior to other standard testers on the market.
Measurement precision is more critical for long‐term battery testing and long‐term battery projections than control accuracy alone. Most other battery testing systems do not correctly specify their precision and/or have relatively poor precision, which hinder the conclusions drawn from results data. Important trends and electrochemical indicators may remain unnoticed; lost in the measurement noise as illustrated at right.

CANBus
Arbin offers CANBus interface(s) to allow real-time external control of the Arbin tester using CAN protocol. This feature allows for battery module/pack communication with a BMS (battery management system) or for cell testing where the client needs external control via CAN.
MTCI
The Temperature Chamber Interface (MTCI) allows the Arbin system to communicate with an approved third-party temperature/environment chamber. Arbin’s software can turn the chamber on/off and adjust the temperature during the test.
Battery Racks & Holders
A variety of racks and battery holder are available for all cell types for an organized test environment.
Arbin offers thermocouple and thermistor sensor types to measure and record temperature during testing. They function independently so the user may flexibly assign them in any configuration with the main charge/discharge test channels. All data is automatically synchronized with the cell charge/discharge test data. Available sensor types include:
- K-Type Thermocouples
- T-Type Thermocouples
- PT100 Thermistor (NOTE: PT100 thermistor inputs are compatible with Arbin MZTC Multi-Chamber.)
- 10kOhm Thermistor
Arbin offers an optional AutoCal module which can be used to re-calibrate the system when needed. All Arbin test equipment include a calibration interface as standard that can use an external meter to check or perform re-calibration. The AutoCal module is used to automate this process and will function without the need for an external meter.
NOTE: Arbin recommends equipment calibration is checked annually and re-calibrated as-needed.
AutoCal modules are available rated up to 200A, and High precision shunts are also available to use up to 600A.
