Alaris Medicalsystems 7000 Infusion Pump Compatible Battery 12V 3000mAh

Alaris Medicalsystems 7000 / 7100 Series — 12V Ni-MH Replacement Battery (141788)

This is a 12V, 3000mAh nickel-metal hydride replacement battery for the Alaris Medicalsystems 7000, 7100, 7130, and 7131 infusion pump series, plus over 25 additional compatible models. It replaces OEM part numbers 141788, 8392, B11044, OM11044, and 141780. The battery slots into the same bay and connects through the same BMS interface as the factory cell.

• 7000 / 7100 series compatibility: The 7000, 7100, 7130, and 7131 share a common 12V power architecture and the same battery bay connector. All models use the same BMS handshake protocol, so one cell revision covers the full platform without any wiring or adapter changes.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the 7100 platform. The BMS accepted the new cell, completed its verification handshake, and passed all charge-state thresholds without fault codes on both the first and second cycles.
• Post-swap self-test protocol: After installing the battery, let the pump complete its full power-on self-test without removing power or pressing any keys. The Alaris BMS runs a battery verification step at boot — interrupting it before completion logs a false battery fault that stays active until the next clean restart.

Device not completing boot sequence on a new battery

The Alaris 7000 series BMS checks cell voltage at startup against a minimum threshold before allowing the pump to reach ready state. A new Ni-MH cell that has been in storage can read as low as 10.5V due to self-discharge, which sits below the BMS recovery threshold. The pump stalls mid-boot or loops back to the start screen. Connect the pump to AC power, allow a full uninterrupted charge to complete, then power cycle — the cell should read above 12V and boot normally.

Charge indicator not reaching 100% on the first charge after swap

The Alaris charge IC applies a conservative current limit on the first charge cycle when it detects a new or unrecognised cell. This means the indicator may stop at 85–90% and the pump reports a partial charge state. This is not a fault — the charge controller is running a calibration pass on the new cell's internal resistance profile. Run one complete charge-discharge cycle in normal operation, and the indicator will register full capacity from the second charge onward.
