Bosch 908BPV144-01 Cordless Vacuum Replacement Battery 14.4V

Bosch BCHF2MX16 Readyy'y Serie 2 — 14.4V Li-ion Replacement Battery (908BPV144-01)

This 14.4V 3400mAh Li-ion battery pack replaces the original 908BPV144-01 cell in the Bosch BCHF2MX16, BCHF2MX16/04, Readyy'y Serie 2, and VXAS012V14 cordless vacuums. When the original pack degrades, suction drops noticeably before the low-battery indicator even activates. This replacement restores the full voltage rail the motor needs to maintain consistent airflow across cleaning sessions.

• BCHF2MX16 and VXAS012V14 compatibility: These models share the same 14.4V battery bay, connector pinout, and BMS handshake protocol — one pack fits all four listed variants without modification.
• Bench tested on actual hardware: We ran this pack through full charge and discharge cycles on the BCHF2MX16 platform. The BMS handled motor-start inrush current cleanly and held voltage above the 12V cutoff threshold under sustained suction load.
• Dock charging habit on Readyy'y Serie 2: Do not leave this vacuum sitting on the charging dock permanently. Bosch's cordless vacuum charger does not cut trickle current once the pack is full. Cells left on continuous dock charge lose capacity measurably faster than packs charged only when depleted — charge to full, then remove.

Suction dropping before the battery indicator reaches low on the BCHF2MX16

The BCHF2MX16 motor draws significantly more current when the filter is partially blocked — airflow restriction forces the motor to work harder, pulling the pack voltage down earlier than the indicator expects. The battery indicator is calibrated against a clean-filter draw rate, so voltage sag under a dirty filter reads as normal until the pack can no longer sustain it. A degraded original cell compounds this: internal resistance rises with age, accelerating voltage drop under load. Check and clean the filter first; if suction still drops early with this replacement pack installed, the filter is the cause, not the battery.

Motor cutting out mid-session and then recovering after a few seconds

This is a BMS overcurrent trip, not a dead battery. When the vacuum picks up a blockage or the filter is heavily restricted, current draw spikes past the BMS protection threshold and the pack shuts the circuit. After a few seconds the BMS resets and the motor restarts — the cycle then repeats if the restriction is still present. Clear any blockage in the nozzle or hose and inspect the filter before assuming the pack is faulty. If the motor runs without cutting out after clearing the restriction, the BMS is functioning correctly at its rated trip point.
