Bollywood E30 ECG Compatible Battery 11.1V 3400mAh LB-05

Bollywood E30 ECG — 11.1V Li-ion Replacement Battery (LB-05)

This 11.1V, 3400mAh Li-ion battery replaces the original cell in the Bollywood E30 ECG portable electrocardiograph monitor. It fits the E30 ECG directly, matching the OEM part numbers LB-05 and 12-100-0015. Capacity figure is taken from product specification, not estimated.

• E30 ECG platform fit: The E30 ECG runs a single 11.1V Li-ion pack with a BMS that handshakes on connector pin-out and cell chemistry. This replacement matches that voltage rail and chemistry so the device recognises the pack at startup without throwing a fault code.
• Bench tested on actual hardware: We cycled this cell through the E30 ECG's power-on self-test sequence. The BMS completed charge verification, reported state-of-charge correctly, and held voltage within tolerance across the device's typical clinical load profile.
• Post-installation self-test protocol: After fitting this battery, let the E30 ECG run its full power-on self-test cycle without interruption. The device's BMS runs a chemistry verification pass at startup — cutting power mid-sequence leaves a false battery fault flag that persists until the next clean reboot.

Device not completing boot sequence on a new E30 ECG battery

The E30 ECG's BMS applies strict voltage thresholds during boot to verify the cell before unlocking clinical functions. A new cell that has partially self-discharged during shipping may sit just below that threshold, causing the boot sequence to stall or abort. This is not a faulty battery — it's the BMS rejecting an unverified state of charge. Plug the device into mains power, allow a full charge cycle to complete, then power on. The BMS should pass its verification at 12.6V or above.

Charge indicator not reaching 100% on the first charge after fitting

On the first charge, the E30 ECG's charge IC applies a conservative current ceiling to a cell it hasn't profiled yet. This means the indicator may plateau at 90–95% and stop climbing. It reads as a full charge internally once the IC finishes its initial calibration pass, but the display lags behind. Run one complete charge-discharge-recharge cycle before relying on the percentage readout for clinical scheduling. After that first cycle, the reported figure will align with actual cell capacity.
