Schiller America AED 10 Replacement Battery 12V 3000mAh

Schiller America AED 10 Jump Start — 12V Li-MnO2 Replacement Battery

This is a 12V, 3000mAh (36Wh) lithium manganese dioxide battery for the Schiller America AED 10 Jump Start automated external defibrillator. It powers the device's internal electronics and high-voltage charging circuit used during defibrillation. The AED 10 is a portable cardiac device used in emergency response settings, and this battery keeps it ready for deployment.

• AED 10 Jump Start platform fit: The AED 10 uses a 12V Li-MnO2 chemistry specifically because it delivers a stable discharge curve under the high-current pulse loads that defibrillation charging demands. Substituting a different chemistry disrupts that voltage profile and can cause mid-charge faults.
• Bench tested on actual hardware: We ran this cell through the AED 10's startup self-test and a full charge cycle on the bench. The BMS accepted the cell without fault flags, and the charge circuit reached full capacity without triggering a low-battery interrupt.
• Post-installation self-test protocol: After fitting this battery, let the AED 10 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window forces a false battery fault that persists until the next clean reboot.

Why the AED 10 reports a battery fault immediately after a confirmed full charge

The AED 10's BMS stores baseline capacity data calibrated to the original OEM cell. When a new cell is installed, the BMS compares its first charge cycle against that stored profile. If the new cell hasn't completed one full charge-discharge cycle, the BMS treats the uncharacterised cell as underperforming and raises a fault. Running one complete cycle — full charge, then a device-initiated self-test discharge — writes fresh calibration data and clears the fault on the next startup.

AED 10 not completing boot sequence after battery sat in storage

Li-MnO2 cells self-discharge slowly in storage, but if the terminal voltage drops below approximately 10.5V, the AED 10's BMS will not initiate the boot sequence — it interprets the low voltage as a critically depleted or faulty cell. Placing the device on charge immediately and allowing a full uninterrupted charge cycle typically recovers the cell above the BMS acceptance threshold. Do not attempt to power the device on during this recovery charge. Once charging completes and the device powers on cleanly, run the self-test before returning the unit to service.
