Eureka E10s Replacement Battery 14.4V 6700mAh BP14452C

Eureka E10s Series — 14.4V Li-ion Replacement Battery (BP14452C)

This is a 14.4V Li-ion replacement battery for the Eureka E10s cordless stick vacuum. It fits models E10s, NERE10S-EU-VD, EA100001, and EA100003. Capacity is 6700mAh (96.48Wh), matching the original specification from the factory.

• E10s platform fit: All four fit models run the same 14.4V motor rail and share the BP14452C connector and BMS handshake. The pack snaps into the handle dock and the BMS communicates directly with the vacuum's motor controller to regulate output and protect against overcurrent.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on an E10s body. The BMS held the 14.4V rail steady under sustained suction load, tripped correctly when we deliberately restricted airflow to simulate a blocked filter, and recovered after clearing the restriction.
• Dock charging behaviour on the E10s: The E10s charging dock does not cut power once the cell reaches full charge. Leaving the vacuum on the dock permanently applies a low-level trickle that accelerates capacity fade. Charge to full, then remove the vacuum from the dock and store it off the charger.

Suction dropping before the battery indicator reaches low

The E10s motor draws more current when airflow is restricted — a clogged filter or partially blocked brush roll forces the motor to work harder to maintain suction. Under that elevated draw, the cell voltage sags below the motor controller's threshold before the battery indicator registers as low. The indicator reads state of charge, not voltage under load, so the two don't always match. Clean the filter and check the brush roll before concluding the battery is the cause.

Motor cuts out mid-clean, then restarts after a few seconds

This is a BMS overcurrent trip, not a dead cell. When the motor sustains a high-current draw — typically from a restricted filter or a tangle in the brush roll — the BMS shuts output to protect the cells. The pack resets automatically once temperature and current normalise, which is why the vacuum restarts after a short pause. Remove the restriction, then check that the filter is fully dry if it was recently washed. A wet filter increases resistance and can trigger the same trip repeatedly.
