It fits directly into the M-288 and restores power to the motor and suction system. No OEM part number is published for this model — match by voltage, chemistry, and physical dimensions (179 x 51 x 52mm) before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM-288 platform fit:\u003c\/strong\u003e\n    The M-288 runs a 14.4V Ni-MH cell pack because the motor controller is tuned to that voltage rail. Swapping to a different voltage or chemistry will mismatch the charge curve and can damage the controller board.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell pack through repeated full charge and discharge runs on the M-288 motor load. The BMS held voltage within spec under continuous suction draw and did not trip on startup current.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the M-288:\u003c\/strong\u003e\n    Remove the vacuum from the charging dock as soon as it reaches full charge. Ni-MH cells in continuous dock contact receive a trickle current that accelerates capacity fade — this is a known failure mode specific to always-docked cordless vacuums.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping before the battery indicator reaches low on the M-288\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells under sustained motor load show voltage sag well before the charge indicator triggers a low warning. The M-288 motor draws more current when the filter is partially blocked, which accelerates that voltage sag. The result is reduced suction that appears to be a battery fault but is actually a motor load issue. Clean or replace the filter first — if suction recovers, the battery is not the root cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eM-288 motor cutting out mid-clean and then recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a battery failure. When suction airflow is restricted — blocked filter, clogged inlet, or tight carpet pile — the motor pulls above its rated current draw. The BMS shuts the cell pack down to protect the cells, then resets after a brief cool-down. Clear the restriction, check the filter, and resume use. If trips continue on a clean filter, verify the replacement pack is 14.4V Ni-MH and not a mismatched chemistry.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428087398490,"sku":"BWCS-IRB400VX-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428087431258,"sku":"BWCS-IRB400VX-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428087464026,"sku":"BWCS-IRB400VX-3","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB400VX-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/ikasumoto-m-288-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
