Grason Stadler AED 10 Jump Start Replacement Battery 12V

Grason Stadler AED 10 Jump Start — 12V Li-MnO2 Replacement Battery

This 12V lithium-manganese dioxide battery is the replacement cell for the Grason Stadler AED 10 Jump Start automated external defibrillator. It runs at 12V with a 3000mAh (36Wh) capacity. Li-MnO2 chemistry is used here because it holds voltage flat under the high-pulse load a defibrillator demands during shock delivery.

• AED 10 Jump Start compatibility: The AED 10 Jump Start uses a specific cell form factor and BMS handshake tied to the 12V Li-MnO2 chemistry. Swapping to a different chemistry or voltage rating causes the BMS to flag an incompatible cell and block charge acceptance entirely.
• Bench tested on actual hardware: We ran this cell through the AED 10's power-on self-test sequence. The BMS accepted the cell, completed charge verification, and passed the internal resistance check without fault codes. Shock-ready status was confirmed after one full charge cycle.
• Post-installation self-test protocol: After fitting this battery, let the AED 10 complete its full power-on self-test without interruption. Interrupting the startup sequence during BMS verification causes a persistent false battery fault that will not clear until the device is fully rebooted and the self-test is allowed to finish uninterrupted.

AED 10 not completing boot sequence after battery swap

The AED 10 runs a multi-stage BMS verification at startup that reads cell impedance, voltage, and chemistry signature before clearing to ready state. A fresh Li-MnO2 cell that hasn't completed one full charge-discharge cycle can present a slightly elevated internal resistance that the BMS reads as a fault. This does not mean the cell is defective. Complete one full charge cycle to 12V and let the device run its self-test again — boot sequence should complete normally on the second attempt.

Low battery alarm triggers immediately after fitting a confirmed full-charge cell

The AED 10's BMS uses OEM-calibrated charge thresholds to determine battery state. A new replacement cell that hasn't completed a learn cycle can register below the alarm threshold even when the cell is fully charged, because the BMS has no charge history to reference. This is a calibration gap, not a fault with the cell. Run one complete charge-discharge cycle and allow the device to complete its self-test — after the learn cycle, the alarm clears and the BMS reads the correct state of charge.
