Zoncare IMAC100 Compatible Battery 14.8V 5200mAh

Zoncare IMAC100 / iMAC 1200 Series — 14.8V Li-ion Replacement Battery (WPF12-0068)

This is a 14.8V, 5200mAh Li-ion replacement battery for the Zoncare IMAC100 and iMAC 1200 series patient monitors. It replaces OEM part WPF12-0068 and restores portable power to clinical monitoring devices used for continuous vital sign tracking. Capacity figure is taken directly from product specifications at 76.96Wh.

• IMAC100, IMAC1200, iMAC 1200, iMAC 120B compatibility: These models share the same 14.8V battery platform, connector pinout, and BMS handshake protocol. A single cell format covers the full range without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge under the IMAC100 load profile. The BMS accepted the cell on first insertion and completed charge termination at the correct 16.8V cutoff without faulting.
• Post-swap self-test handling: After installing this battery, allow the monitor to complete its full power-on self-test without interruption. Medical device BMS verification runs at startup — cutting power mid-sequence trips a false battery fault that persists until the next clean reboot.

Charge indicator not reaching 100% on first charge after installation

The IMAC100 charge IC applies a conservative current limit on cells it hasn't logged before. On the first charge cycle, the monitor may display 95–98% and hold there before terminating. This is the charge algorithm being cautious with an unrecognised cell, not a fault in the battery or the monitor. Run one complete charge-discharge cycle and the charge IC recalibrates its endpoint. After that cycle, the indicator reaches 100% and terminates normally.

Monitor will not power on after the replacement cell sat in storage

Li-ion cells self-discharge during storage. If this battery sat long enough to drop below approximately 10V–11V, the IMAC100 BMS will block power delivery as a deep-discharge protection measure. The device appears completely dead — no boot screen, no alarm. Connect the monitor to mains power first and leave it on charge for at least 30 minutes before attempting to power on. This allows the charge IC to bring the cell above the BMS recovery threshold before the device tries to draw startup current.
