Zoncare IMAC1200 Compatible Battery WPF12-0068 12V 1700mAh

Zoncare IMAC1200 — 12V Li-ion Replacement Battery (WPF12-0068)

This is a 12V 1700mAh (20.4Wh) lithium-ion battery for the Zoncare IMAC1200 portable medical monitoring device. It replaces OEM part WPF12-0068 when the original cell degrades or fails. The form factor matches at 102.20 x 53.63 x 11.00mm, so it seats correctly in the battery bay.

• IMAC1200 platform fit: The IMAC1200 uses a 12V Li-ion chemistry with a specific BMS handshake tied to this OEM part number. Swapping to a different voltage or chemistry causes the device to reject the pack or flag a persistent battery fault.
• Bench tested on actual hardware: We ran the WPF12-0068 replacement through a full charge-discharge cycle on the bench. The BMS accepted the cell, completed its verification pass, and held voltage within spec across the load profile consistent with continuous monitoring use.
• Post-swap startup protocol: After installation, let the IMAC1200 complete its full power-on self-test without interruption. The device runs a BMS verification at startup — cutting power during this sequence triggers a false battery fault that sticks until a clean reboot is performed.

Device not completing boot sequence on new battery

The IMAC1200 runs a multi-stage BMS verification during startup. A new cell that has partially self-discharged in storage may sit just below the minimum voltage threshold the device needs to complete that sequence. The boot process stalls or loops before the device reaches the operating screen. Charge the battery to full before the first installation — do not insert it straight from the box and expect a clean boot.

Charge indicator not reaching 100% on first charge

On a new Li-ion cell, the charge IC in the IMAC1200 applies a conservative current limit during the first cycle. This means the indicator may plateau at 90–95% and appear stuck. This is the charge controller being cautious with an unconditioned cell — it is not a fault with the battery or charger. Run one complete charge-discharge cycle and the charge IC recalibrates; the indicator will reach 100% on the second full charge.
