Datrend Infutest 2000 Compatible Battery 7.2V 2200mAh

Datrend Infutest 2000 — 7.2V Ni-MH Replacement Battery (110856)

This 7.2V, 2200mAh Ni-MH battery replaces the OEM cell in the Datrend Infutest 2000 Infusion Device Analyzer and the Oxitest Plus 7 SpO2 Simulator. Both instruments draw sustained low-current loads during pump testing and calibration procedures. Capacity is 15.84Wh — matching the original specification exactly.

• Infutest 2000 and Oxitest Plus 7 platform fit: Both instruments share the same 7.2V cell format, connector pinout, and BMS handshake protocol. One replacement cell covers both analyzers in a facility running mixed Datrend equipment.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the Infutest 2000 platform. The BMS accepted the cell without fault flags, and the charge IC completed a full cycle without tripping the thermal cutoff.
• Post-swap startup protocol: After installing this cell, let the analyzer complete its full power-on self-test without interruption. The BMS runs a verification sequence at startup — cutting power during this window registers a false battery fault that persists until the next clean reboot.

Charge indicator not reaching 100% on the first cycle after installation

The Infutest 2000 charge IC applies a conservative current limit when it first encounters a new cell. On the initial charge, the indicator may stall between 85% and 95% before the device declares the cycle complete. This is a calibration behaviour — the charge IC has not yet profiled the cell's internal resistance. Run one full charge-discharge cycle, then recharge to 100%. After that first conditioning cycle, the charge IC tracks the cell accurately.

Device will not power on after the replacement cell sat unused in storage

Ni-MH cells self-discharge at roughly 1–3% per day at room temperature. A cell stored for several weeks can drop below the Infutest 2000's BMS recovery threshold — typically around 5.5V for a 7.2V pack — and the instrument will not boot. Connect the charger and leave it for a full charge cycle before attempting power-on. If the charge LED does not illuminate within five minutes of connection, the cell voltage has dropped below the charge IC's detection floor and requires a compatible external Ni-MH charger to recover to 6.0V before the instrument's onboard charger will take over.
