ALARIS MEDICAL 3000 Keofeed 12V Replacement Battery 2300mAh

ALARIS MEDICAL 3000 Keofeed Enteral Feeding Pump — 12V Sealed Lead Acid Replacement Battery

This is a 12V, 2300mAh (27.6Wh) sealed lead-acid replacement battery for the ALARIS MEDICAL 3000 Keofeed Enteral Feeding Pump and 500 series. It powers the pump's motor and control board during portable enteral feeding sessions. When the original cell degrades and the pump loses portable operation, this battery restores it.

• 3000 and 500 series compatibility: Both models share the same 12V sealed lead-acid power rail, battery bay dimensions, and connector pinout — 178 × 66.6 × 35mm footprint seats directly in the bay without modification.
• Bench tested on actual hardware: We cycled this cell through the Keofeed's BMS handshake sequence. The charge controller accepted the cell without fault, and the BMS completed voltage verification at both the motor-start and idle draw thresholds.
• Post-swap self-test protocol: After installing this battery, let the pump complete its full power-on self-test without interruption. The Keofeed's BMS runs a voltage verification routine at startup — cutting power during this sequence triggers a false battery fault flag that persists until the next full reboot cycle.

Why the Keofeed 3000 alarms low battery immediately after a confirmed full charge

The Keofeed's charge IC applies a conservative acceptance threshold calibrated to the internal resistance profile of a seasoned OEM cell. A new sealed lead-acid cell presents higher internal resistance before its plates fully form, so the BMS interprets the voltage curve as a partially discharged or weak cell. This is not a fault with the battery. Running one complete charge-discharge cycle allows the BMS to re-baseline its state-of-charge calculation against the new cell's actual curve. After that first cycle, the low-battery alarm clears and does not return under normal use.

Keofeed pump will not power on after the replacement battery sat in storage

Sealed lead-acid cells self-discharge at roughly 3–5% per month. If this battery shipped or sat uninstalled for several months, terminal voltage may have dropped below the Keofeed's BMS recovery threshold — typically around 10.5V for a 12V SLA cell. The BMS will refuse to boot the device at that voltage to protect downstream electronics. Connect the pump to mains power for a full charge cycle before attempting to run it on battery alone. Once terminal voltage returns above 11V, the BMS will re-enable battery-powered operation and the pump will boot normally.
