Revitive Medic Plus 3.7V Replacement Battery D3706008a

Revitive Medic Plus — 3.7V Li-ion Replacement Battery (D3706008a)

This is a 3.7V, 1500mAh Li-ion replacement battery for the Revitive Medic Plus and Medic PLUS Circulation Booster. It slots directly into the handheld electrical muscle stimulation unit and restores power to the device's therapeutic circulation function. OEM part number D3706008a cross-references to this cell.

• Medic Plus and Medic PLUS Circulation Booster compatibility: Both models share the same 3.7V cell format, BMS handshake protocol, and D3706008a part number — one cell covers both variants without any hardware modification.
• Bench tested on actual hardware: We ran this cell through full charge and discharge cycles on the Medic Plus platform. The BMS accepted the cell, passed the startup verification routine, and held voltage within the expected range across the EMS output load.
• Post-swap startup protocol: After installing this battery, allow the Revitive to complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window triggers a false battery fault that sticks until the next clean reboot.

Why the Medic Plus reports low battery immediately after a confirmed full charge

The Revitive BMS uses a charge-history table to validate cell state — a freshly installed cell has no history, so the device reads the absence of data as a low-charge condition. This clears after one complete charge-discharge cycle, which lets the BMS build a baseline for the new cell. Until that cycle runs, the low-battery indicator is a calibration gap, not a cell fault. Charge the unit fully, run it through one complete EMS session, then charge again to reset the threshold.

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

Li-ion cells self-discharge during storage — if this battery sat at the distributor or in transit for several months, its resting voltage may have dropped below the Revitive's BMS recovery floor, typically around 2.5V. A cell below that threshold causes the device to show no response at all when the power button is pressed. Connect the charger and leave it for at least 60 minutes before attempting to power on — most BMS controllers include a trickle pre-charge circuit that recovers cells from this state. If the charge LED lights up, the cell is recovering; let it reach full charge before powering on the device.
