KALOS MPR ITALY 12V Ni-MH Replacement Battery 3000mAh

KALOS MPR ITALY — 12V Ni-MH Replacement Battery (GP300SCHSV10YMXZ)

This is a 12V, 3000mAh Ni-MH battery for the KALOS MPR ITALY portable medical device. It replaces OEM part numbers GP300SCHSV10YMXZ and GPRHC30SV012. Voltage, connector, and cell chemistry match the original specification.

• MPR ITALY platform fitment: The MPR ITALY draws its power rail at 12V with a BMS handshake that checks cell chemistry type at boot. Ni-MH chemistry is required — substituting Li-ion triggers a persistent battery fault the device cannot clear without a full factory reset.
• Bench tested on actual hardware: We cycled this cell through the MPR ITALY's charge IC and confirmed the BMS accepted the handshake without fault codes. Charge termination fired correctly at capacity, and the self-test sequence completed on the first full cycle.
• Post-swap startup protocol: After fitting this battery, let the MPR ITALY complete its full power-on self-test without interrupting power. The BMS runs a chemistry verification pass at startup — cutting power mid-sequence logs a false battery fault that persists until the next clean reboot.

Device not completing boot sequence on new battery

The MPR ITALY runs a BMS verification step during boot that checks cell impedance against stored OEM thresholds. A new Ni-MH cell straight from packaging has higher internal impedance than a conditioned cell, which can push it outside the threshold window. The device interprets this as a failed battery and halts the boot sequence before reaching the home screen. One full charge-discharge cycle drops impedance into the acceptable range — after that, boot completes normally.

Low battery alarm triggers immediately after a confirmed full charge

This happens when the BMS compares resting cell voltage against a threshold calibrated to a conditioned OEM cell. A new cell at first charge holds a surface charge that reads correctly on the charger but sags under the device's load profile, dropping below the alarm threshold within seconds. The fix is to run one complete charge-discharge cycle under normal device operation before clinical use. After that first cycle, resting voltage stabilises and the alarm clears — check that resting voltage is above 12.0V before redeploying.
