It replaces the original pack when capacity has faded and the vacuum no longer holds a useful charge. Dimensions are 136.10 x 55.90 x 47.20mm — confirm fit before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eM-488 platform fit:\u003c\/strong\u003e\n    The M-488 runs a 14.4V battery rail with a Ni-MH cell stack — this replacement matches that voltage and connector configuration. Swapping chemistry or voltage on this vacuum will cause the charger circuit to behave incorrectly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the M-488 charge cycle and monitored BMS response under normal floor and carpet load. Cell balancing remained stable and the pack reached full charge without triggering thermal cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the M-488:\u003c\/strong\u003e\n    Do not leave the M-488 sitting on the charging dock after the pack is full. Ni-MH cells in continuous trickle charge degrade significantly faster than cells charged only when depleted. Charge to full, then remove from dock.\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-488\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells lose voltage under load before the resting voltage drops enough to trigger the low-battery indicator. On the M-488, a partially blocked filter forces the motor to draw more current than rated, which accelerates that voltage sag under load. The result is noticeably weaker suction while the indicator still shows charge remaining. Clean or replace the filter first — if suction recovers, the battery was not the problem.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eM-488 motor cuts out mid-clean and then restarts after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the filter is partially blocked, airflow restriction causes the motor to draw sustained current above the pack's trip threshold. The BMS cuts power to protect the cells, then resets after a short recovery window. Clear the filter and check for blockages in the suction path before assuming the battery pack is faulty — if the motor still trips on a clean filter, measure resting voltage and confirm the pack holds above 13.0V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428059447386,"sku":"BWCS-IRB560VX-1","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428059480154,"sku":"BWCS-IRB560VX-2","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428059512922,"sku":"BWCS-IRB560VX-3","price":122.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB560VX_1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/auto-cleaner-intelligent-floor-vac-m-488-replacement-battery-144v-4000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
