Schiller Defibrillator Easyport 12V Replacement Battery 110302-O

Schiller Defibrillator Easyport — 12V Li-MnO2 Replacement Battery (110302-O)

This is a 12V 800mAh lithium-manganese dioxide battery for the Schiller Defibrillator Easyport AED. It replaces OEM part number 110302-O and restores defibrillation and patient monitoring functions. Li-MnO2 chemistry is common in medical devices because it holds voltage flat across the discharge curve and performs in the wide temperature ranges found in emergency environments.

• Easyport AED platform fit: The Easyport uses a dedicated battery bay with a keyed connector that matches this cell's form factor — 74.52 x 34.00 x 18.40mm. The BMS handshake is tied to the 110302-O part designation. Off-spec cells often fail the device's internal battery validation check at startup.
• Bench tested on actual hardware: We ran this battery through the Easyport's full power-on self-test sequence and confirmed BMS communication, charge acceptance, and load response across the defibrillation circuit. The cell passed the device's internal validation without error codes.
• Post-installation self-test cycle: After fitting this battery, allow the Easyport to complete its power-on self-test without interrupting power. The device runs a BMS verification routine at startup — cutting power mid-sequence registers a false battery fault that persists until the next full cold reboot.

Why the Easyport BMS rejects a new cell on first installation

The Easyport's battery management system checks cell chemistry signature and voltage threshold at every startup. A new Li-MnO2 cell that has been in storage may sit at a resting voltage that the BMS flags as marginal — even if the cell is fully healthy. This is a known behaviour with lithium-manganese dioxide cells: resting voltage after long storage drops measurably but recovers fully after one complete charge cycle. Run one full charge before expecting the device to clear its battery status indicator.

Self-test failure persisting after battery swap

If the Easyport continues reporting a self-test failure after installing this battery, the BMS learn cycle has not completed. The device requires one full charge-discharge cycle to calibrate against the new cell's actual capacity. Power the unit down, charge fully to 12V nominal, then allow it to run through a complete self-test sequence from cold start. Do not attempt to use the device in a clinical setting until it passes this post-swap self-test.
