Proscenic Pro coco E718074 Replacement Battery 14.4V 2500mAh

Proscenic Pro coco / Smart 680T / 902S — 14.4V Ni-MH Replacement Battery (E718074)

This is a 14.4V, 2500mAh (36Wh) Ni-MH replacement battery for the Proscenic Pro coco, Smart 680T, 902S, and 902 NONO cordless stick vacuums. It replaces OEM part number E718074. When the original pack can no longer sustain motor voltage under load, this cell restores the vacuum to full working condition.

• Pro coco, Smart 680T, 902S, and 902 NONO compatibility: These four models share the same 14.4V battery rail, connector pinout, and BMS handshake protocol. One pack covers all four without any modification or adapter.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the Pro coco platform. The BMS held steady across sustained motor draw and tripped correctly under simulated blockage — no false cutoffs at normal operating load.
• Dock charging habit on cordless vacuums: Do not leave this vacuum sitting on the charging dock permanently. Ni-MH cells on continuous trickle charge develop capacity fade significantly faster than cells charged only when depleted. Charge to full and remove from the dock.

Suction dropping before the battery indicator reaches low

This happens when the motor draws more current than rated — usually because a partially blocked filter forces the motor to work harder. The BMS reads the elevated draw as a low-voltage event and begins throttling output before the indicator catches up. The indicator tracks cell state-of-charge, not motor load, so the two fall out of sync under restriction. Clean or replace the filter first before assuming the battery is at fault.

Motor cutting out mid-clean and then recovering after a pause

This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, tangled brush roll, or sealed nozzle — motor current spikes above the BMS threshold and the pack shuts down to protect the cells. The brief pause lets the BMS reset and allows the cells to recover voltage above the cutoff floor. Clear the restriction, then restart the vacuum. If the cutout repeats on an unblocked machine, check that the replacement pack voltage reads at least 16.0V fully charged before use.
