Dyson V10 Cordless Vacuum Replacement Battery 25.2V 2500mAh

Dyson V10 Cyclone Series — 25.2V Li-ion Replacement Battery (969352-02)

This 25.2V 2500mAh (63Wh) lithium-ion battery replaces the original cell in the Dyson V10, Cyclone V10, and V10 Absolute cordless stick vacuums. It fits the SV12 platform and matches OEM part numbers 969352-02 and 206340. Capacity figure is from the product specification — not extrapolated from the original cell.

• V10 SV12 platform fit: All V10 variants — Absolute, Animal, Fluffy, and Total Clean — share the same SV12 motor board and battery connector. The BMS handshake protocol is identical across the range, so one cell covers the full series without modification.
• Bench tested on actual hardware: We ran this cell on an SV12 unit through full charge and discharge cycles. The BMS reported accurate state-of-charge, the motor spun up cleanly across all three power modes, and no overcurrent faults were logged during sustained MAX mode operation.
• Dock charging habit on the V10: Do not leave the V10 sitting on the wall dock permanently. Continuous trickle charging compresses cell capacity faster than standard use does. Charge to full, then remove from the dock until the next clean.

Suction dropping before the battery indicator reaches low

The V10 motor draws significantly more current when the filter is partially blocked or the bin is full — the motor fights restriction rather than airflow. Under that elevated draw, cell voltage sags early and the BMS throttles output before the LED indicator registers a low state. The vacuum feels like it's losing charge when the real cause is mechanical restriction upstream of the motor. Clean the filter and empty the bin first — if suction recovers immediately, the battery was never the problem.

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

This is a BMS overcurrent trip, not a failed battery. When sustained suction restriction forces the motor to draw beyond the cell's rated discharge threshold, the BMS opens the circuit to protect the cell — then resets once current demand drops. It happens most often on MAX mode with a partially blocked cyclone head or compressed filter. Clear the restriction, reset the vacuum by switching off and back on, and confirm resting cell voltage sits above 22V before resuming.
