Philips Aqua Series 5000 25.2V Replacement Battery 2441846-62

Philips Aqua Series 5000 — 25.2V Li-ion Replacement Battery (2441846-62)

This 25.2V, 2500mAh lithium-ion battery replaces the original pack in the Philips Aqua Series 5000, Series 9000, and XC5041 cordless stick vacuums. It matches the OEM part number 2441846-62 and slots into the same battery bay with no modification. Capacity is 63Wh — identical to the factory specification.

• Series 5000 and Series 9000 compatibility: Both vacuum lines run the same 25.2V cell architecture and share the 2441846-62 battery connector and BMS handshake protocol, which is why one pack covers both series without adaptation.
• Bench tested on actual hardware: We ran this pack through full charge-discharge cycles on the XC5041 platform. The BMS communicated correctly with the charger, the fuel gauge reported accurately across the range, and no overcurrent trip occurred during motor start.
• Dock charging habit for this vacuum: Do not leave the vacuum on the charging dock continuously. Philips cordless vacuums on permanent dock charge develop capacity fade faster than units charged only when the battery is depleted — charge to full, then remove it.

Suction dropping before the battery indicator reaches low

This happens when a blocked filter forces the motor to draw current above its rated load. The BMS detects the elevated draw and reduces output voltage to protect the cells, which the motor reads as low power — not a low battery. The indicator stays mid-range because cell voltage is still healthy. Clean or replace the filter first; if suction restores immediately, the battery was never the problem.

Motor cuts out briefly on carpet then recovers on its own

This is a BMS overcurrent trip, not a battery fault. On thick carpet or when the brush roll is partially blocked, sustained restricted airflow causes the motor to spike current draw sharply. The BMS cuts the circuit to prevent cell damage, then resets once current normalises. Clear any brush roll obstruction and confirm filter airflow is unrestricted — if the trip stops occurring, the pack is functioning correctly.
