Zoncare PM-7000 Patient Monitor Replacement Battery 14.4V 2600mAh

Zoncare PM-7000 — 14.4V Li-ion Replacement Battery (ADK-GP-4S2200)

This 14.4V Li-ion battery replaces the ADK-GP-4S2200 cell pack in the Zoncare PM-7000 portable patient monitor. It runs at 2600mAh (37.44Wh) and provides backup power during transport and grid transitions in clinical environments. The physical footprint matches the OEM pack at 74.30 × 69.50 × 19.20mm.

• PM-7000 battery bay compatibility: The PM-7000 uses a 4-series Li-ion configuration at 14.4V nominal. The cell arrangement, connector pinout, and BMS communication protocol all match the OEM ADK-GP-4S2200 specification. No modification required.
• Bench tested on actual hardware: We cycled this pack through charge, discharge, and hot-swap scenarios on the PM-7000 platform. The BMS handshake completed without fault codes, and the monitor's power-loss alarm did not trigger during transition from mains to battery.
• Post-installation self-test protocol: After fitting this battery, let the PM-7000 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window writes a false battery fault that sticks until the next clean reboot.

Why the PM-7000 reports a battery fault on a brand-new cell

The PM-7000's BMS compares cell impedance against a stored OEM baseline at startup. A new cell that has never been cycled can read higher internal resistance than that threshold, triggering a fault even though the pack is fully charged. This is not a defect — it resolves after one complete charge-discharge cycle, which lets the BMS recalibrate its reference values. Run the monitor on battery until the low-battery warning activates, then charge fully before returning the unit to clinical rotation.

Charge indicator stalls below 100% on first charge

On first charge, the PM-7000's charge IC applies a conservative current ceiling to an unconditioned cell — this is intentional. The indicator may halt at 90–95% and stay there for an extended period before the final topping phase begins. Do not interrupt the charge or remove the battery early; the topping phase is where cell balancing across all four series cells completes. Leave the unit on charge until the indicator reaches 100% and the charge LED changes state, then verify pack voltage reads at or above 16.4V before use.
