About this replacement
Honda HS-101V / HS-102V — 14.8V Li-ion Replacement Battery (HBP-101V)
This 14.8V Li-ion battery replaces the HBP-101V in Honda HS-101V and HS-102V portable medical devices. Capacity is 1850mAh (27.38Wh). It is a direct cell replacement for units where the original battery no longer holds a charge or fails the device self-test.
- HS-101V and HS-102V platform fit: Both models share the same 14.8V four-cell Li-ion architecture, connector pinout, and BMS communication protocol — one battery covers both units without any modification.
- Bench tested on actual hardware: We cycled this battery through charge and discharge on the HS-101V platform. The BMS handshook correctly on first insertion, the charge IC reached full termination voltage, and the device cleared its power-on self-test without a battery fault flag.
- Post-swap startup protocol: After fitting this battery, let the device complete its full power-on self-test cycle without interruption. Medical device BMS firmware runs a capacity verification at boot — cutting power mid-sequence logs a false battery fault that will persist until the next clean full reboot.
Device not completing boot sequence after battery swap
The HS-101V runs a BMS verification step during boot that checks cell voltage against a stored threshold. A freshly installed battery that has not completed one full charge-discharge cycle may report a state-of-charge value the firmware reads as marginal. The device then stalls mid-sequence or loops back to the boot screen. Run one complete charge cycle to let the BMS calibrate its capacity estimate, then reboot — the device should clear the sequence normally.
Charge indicator not reaching 100% on first charge
On the first charge, the HS-101V charge IC applies a conservative current limit to new cells and may terminate early when it detects a voltage plateau it cannot yet classify. The indicator stops at 85–95% and the device reports a partial charge. This is a charge IC learning behaviour, not a faulty battery. Run the device through one full discharge to below 15% state-of-charge, then charge uninterrupted to termination — the IC updates its model and subsequent charges reach 100%.
