Hoover BH50015 18V Replacement Battery 2200mAh Li-ion

Hoover BH50015 Platinum Collection LINX — 18V Li-ion Replacement Battery (BH50000)

This 18V 2200mAh Li-ion battery replaces the original pack in the Hoover BH50015 Platinum Collection LINX Cordless Handheld and the BH50010 Platinum Collection Cordless Stick Vacuum. It also fits Platinum Stick and Platinum LINX variants sharing the same 18V platform. OEM part numbers BH50000 and 302723001 apply across this range.

• BH50015 and BH50010 platform fit: Both models run the same 18V battery rail with an identical connector and BMS communication protocol. A single pack covers handheld and stick configurations without any modification.
• Bench tested on actual hardware: We cycled the battery through repeated full-load runs using a blocked-filter scenario to stress the BMS. Overcurrent protection tripped as expected at sustained high draw, and the cell recovered cleanly on reset with no voltage drop at rest.
• Dock charging on the LINX platform: Do not leave the vacuum sitting on the charging dock between every use. The LINX dock does not cut trickle charge once full, so cells left on continuously develop capacity fade faster than those removed when the charge cycle completes.

Cordless vacuum losing suction before the battery indicator reaches low

This happens when the motor is pulling more current than rated — usually because the filter is partially blocked. A restricted airpath forces the motor to work harder, causing voltage to sag under load even when the cell still holds good charge at rest. The BMS reads that sag as a low-state condition and begins throttling output. Clean the filter first, then recharge to full and retest suction at the nozzle.

Motor cutting out mid-clean and recovering after a few seconds

This is a BMS overcurrent trip, not a dying cell. When suction is restricted — blocked nozzle, clogged filter, or the brush roll jammed — current draw spikes beyond the pack's continuous rating. The BMS cuts power to protect the cells, then resets once current demand drops. Clear the blockage completely, then confirm the resting pack voltage is above 15.5V before resuming use.
