GE Dash 2500 Replacement Battery 8.4V 8000mAh Ni-MH

GE Dash 2500 Patient Monitor — 8.4V Ni-MH Replacement Battery (2023227-001)

This 8.4V, 8000mAh Ni-MH battery replaces the original power cell in the GE Dash 2500 patient monitor. It fits the Dash 2500 and Moniteur Dash 2500 platforms used in hospitals and clinical transport. OEM part numbers 2023227-001, 2023852-029, N1082, and B11773 all cross-reference to this cell.

• Dash 2500 platform fit: The Dash 2500 series uses an 8.4V Ni-MH chemistry with a specific BMS handshake that verifies cell voltage and internal resistance at startup. Cells outside tolerance trigger a battery fault regardless of charge state. This replacement meets those electrical parameters.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge on the Dash 2500 platform. The BMS completed its verification sequence without fault flags, and the monitor transitioned normally from mains to battery power under simulated patient monitoring load.
• Post-swap self-test protocol: After installing this battery, let the Dash 2500 complete its full power-on self-test without interruption. Medical device BMS verification runs at startup — cutting power during this sequence causes a false battery fault that persists until the next complete reboot.

Dash 2500 alarming low battery immediately after a confirmed full charge

The Dash 2500 BMS sets its low-battery threshold against OEM cell chemistry, including internal resistance values. A new Ni-MH cell has higher internal resistance than a conditioned one, which causes the BMS to flag a low-battery state even when the cell is fully charged. This is not a fault with the battery — it resolves after one complete charge-discharge cycle. Run the monitor on battery until it shuts down on its own, then charge fully before clinical use.

Monitor will not power on after battery has been in storage

Ni-MH cells self-discharge during storage, and the Dash 2500 BMS will not attempt to boot if cell voltage falls below approximately 6.0V — it reads the pack as damaged rather than discharged. Place the battery on charge for a minimum of four hours before attempting to power the monitor. If the monitor still will not boot, check that the charge indicator on the unit is active — a non-illuminated indicator means the battery voltage is too low for the charger to have accepted the pack and a trickle-charge recovery cycle may be required.
