Ikasumoto M-288 Cordless Vacuum Replacement Battery 14.4V 3000mAh

Ikasumoto M-288 — 14.4V Ni-MH Replacement Battery

This is a 14.4V 3000mAh Ni-MH replacement battery for the Ikasumoto M-288 cordless vacuum cleaner. It slots into the M-288 to restore power when the original cell has degraded and can no longer hold a useful charge. Dimensions are 179.00 x 51.00 x 52.00mm — verify these against your existing pack before ordering.

• M-288 fitment: The M-288 runs a 14.4V Ni-MH architecture with a motor draw that spikes hard under carpet load. This cell matches that voltage rail and delivers 3000mAh to keep the motor fed through a full cleaning session without triggering low-voltage cutoff prematurely.
• Bench tested on actual hardware: We ran this cell through sustained suction cycles and monitored BMS response under restricted airflow. Voltage held stable across normal load and the protection circuit tripped cleanly on deliberate blockage rather than cutting out randomly.
• Dock charging behaviour on the M-288: Do not leave the M-288 sitting on its charging dock permanently. Ni-MH cells on continuous trickle charge lose capacity faster than cells charged only when depleted. Charge to full, then remove from the dock.

Cordless vacuum losing suction before the battery indicator reaches low

On the M-288, suction drops noticeably while the battery indicator still shows charge remaining. This happens because a partially blocked filter forces the motor to draw more current than rated, which pulls cell voltage down faster than the indicator accounts for. The indicator reads state of charge, not motor load — so it lags behind actual performance. Clean or replace the filter first, then retest suction across a full charge cycle.

Motor cuts out mid-use then recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, clogged brush roll, or a sealed nozzle — the motor draws a sustained high current that the protection circuit reads as a fault. The BMS cuts power, the cell cools briefly, and the circuit resets. Clear the blockage at the brush roll and filter before the next run. If the cutout persists on an unblocked vacuum, check that cell voltage at rest is above 12.0V.
