Vileda VR302 Replacement Battery 14.4V 3000mAh Li-ion

Vileda VR302 — 14.4V Li-ion Replacement Battery (BONA18650-MF1)

This is a 14.4V, 3000mAh Li-ion replacement battery for the Vileda VR302 robotic vacuum cleaner. It slots into the VR302's battery compartment and restores autonomous floor cleaning on hard floors and carpets. Capacity matches the original specification at 3000mAh (43.2Wh).

• VR302 platform fit: The VR302 runs a 14.4V cell architecture with a BMS that monitors pack voltage and current draw during navigation and suction cycles. This replacement uses the same BONA18650-MF1 cell configuration, so the BMS handshake and connector align without modification.
• Bench tested on actual hardware: We cycled this battery through full discharge and recharge sequences on the VR302 platform. The BMS handled motor-start current draw without tripping, and cell balancing held stable across repeated cycles.
• Dock charging habit on robotic vacuums: Do not leave the VR302 sitting on its charging dock permanently between cleaning sessions. Continuous trickle charging accelerates capacity fade in Li-ion cells faster than intermittent charge cycles. Charge to full, then remove the unit from the dock until the next scheduled run.

Suction dropping before the battery indicator reaches low on the VR302

This happens when the filter is partially blocked — the motor has to work harder to pull airflow, drawing more current than the rated load. Under that sustained higher draw, pack voltage sags early and the BMS registers a low-voltage condition before the indicator catches up. The vacuum's suction drops noticeably even though the display shows a healthy charge state. Clean or replace the filter first, then retest — normal voltage sag returns once airflow restriction is cleared.

Motor cuts out mid-cycle then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, tangled brush roll, or a thick rug edge — current spikes past the BMS threshold and it shuts the output to protect the cells. The pack recovers once current drops and the BMS resets. Clear the blockage, check the brush roll for hair wrap, and confirm filter flow is unobstructed before restarting.
