Eureka E10s 14.4V Replacement Battery BP14452C 5200mAh

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

This is a 14.4V, 5200mAh lithium-ion replacement for the original BP14452C battery. It fits the Eureka E10s cordless stick vacuum and related variants including NERE10S-EU-VD, EA100001, and EA100003. Voltage and capacity match OEM spec exactly.

• E10s series compatibility: The E10s, NERE10S-EU-VD, EA100001, and EA100003 all share the same 14.4V battery platform, connector layout, and BMS handshake protocol. One cell fits all four without modification.
• Bench tested on actual hardware: We ran this cell through charge cycles on an E10s dock and monitored BMS communication. The protection circuit responded correctly to overcharge thresholds and discharge cutoff at the expected low-voltage floor.
• Dock charging discipline on the E10s: The E10s charging dock does not stop pushing trickle current when the cell is full. Leave it docked continuously and capacity fade accelerates sharply after a few months. Charge to full, then pull it off the dock.

Suction dropping before the battery indicator reaches low on the E10s

The E10s motor draws well above rated current when airflow is restricted — a clogged filter forces the motor to work harder to maintain suction. That elevated draw causes voltage sag in the cell before the indicator registers a low-battery state. The BMS reads cell voltage, not suction performance, so the indicator lags behind actual power loss. Clean the filter first and check whether suction recovers before replacing the battery.

Motor cutting out mid-clean and then restarting after a few seconds

This is a BMS overcurrent trip, not a dead battery. When the E10s brushroll hits a blockage or the filter is partially restricted, current draw spikes above the BMS threshold and the circuit cuts power. The brief pause is the BMS resetting after the overcurrent event. Clear any blockage at the brushroll, clean the filter, then restart. If the cutout continues on an unobstructed floor, the cell's internal resistance may be high enough to trigger the trip — check resting voltage, which should read above 14.0V on a full charge.
