Globus Elite 4 Replacement Battery 7.2V 2000mAh Ni-MH

Globus Elite 4 / Activa 300 / Premium 200 — 7.2V Ni-MH Replacement Battery

This 7.2V, 2000mAh Ni-MH cell replaces the internal rechargeable battery in the Globus Elite 4 electrotherapy unit and compatible Globus therapeutic devices including the Activa 300 and Premium 200. It matches the original voltage rail and physical footprint at 71.30 × 64.00 × 14.50mm. Capacity is sourced from the product specification — 2000mAh / 14.4Wh.

• Cross-compatible Globus electrotherapy platform: The Elite 4, Premium 200, Activa 300, and nine additional Globus units share the same 7.2V battery bay, connector pinout, and BMS handshake protocol — that is why one cell covers this range without firmware or hardware changes.
• Bench tested on actual hardware: We cycled this cell through a full charge-discharge sequence on the Elite 4 platform and confirmed the BMS accepted the cell, passed its internal voltage check, and cleared the charge complete flag without a fault code.
• Post-installation self-test protocol: After fitting this battery, let the device complete its full power-on self-test without pressing any keys or interrupting the boot sequence. The Elite 4 runs a BMS verification pass at startup — cutting power during this window logs a false battery fault that will not clear until the next uninterrupted cold boot.

Why the Elite 4 triggers a low-battery alarm on a freshly charged replacement

The Elite 4's charge management IC sets its pass threshold against the internal resistance profile of a conditioned OEM cell. A new Ni-MH cell has higher resting impedance straight out of packaging — the device reads this as below-spec and flags it. This is not a faulty battery. One complete charge-discharge cycle lowers the cell's internal resistance into the range the BMS expects. After that first full cycle the alarm clears and does not return.

Device will not power on after the battery sat unused in storage

Ni-MH cells self-discharge at roughly 1–2% per day at room temperature. If a spare battery sat in a drawer for several months, its resting voltage may have dropped below the Elite 4's BMS recovery threshold — typically around 5.5V for a 7.2V pack — and the device simply will not boot. Connect the charger and leave it for a full uninterrupted charge cycle before attempting to power the unit on. If the charge indicator does not light within five minutes of connecting, the cell may need a slow trickle pre-charge; remove and reinsert the charger connector to reinitiate the charge IC handshake.
