It slots in where the original pack sits and restores the vacuum's cleaning cycles. No OEM part number exists for this unit — fitment is confirmed against the M-488 chassis and connector directly.\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 motor rail common to this generation of robotic floor vacs. The connector pinout and BMS communication lines match the original pack, so the vacuum's charge detection and low-voltage cutoff behave as the factory intended.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through full charge and discharge cycles on the M-488 platform. The BMS held cutoff correctly at both ends — no premature shutoff on startup and no over-discharge on depletion. Cell balance stayed within spec across repeated cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the M-488:\u003c\/strong\u003e\n    Do not leave the M-488 sitting on the dock between uses indefinitely. Ni-MH cells in robotic vacuums develop capacity fade faster under continuous trickle charge than cells charged only when the pack is depleted. Charge to full, then remove from the 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  \u003cp class=\"bpw-desc-p\"\u003eThe M-488 motor draws significantly more current when the filter is partially blocked or the brush roll is restricted. That spike pulls the pack voltage down under load — even a healthy, fully charged Ni-MH cell will sag if the motor is working harder than rated. The vacuum's control board reads that voltage sag as a low-battery condition and reduces motor speed, which the user feels as a suction drop. Check and clean the filter first. If the filter is clear and the symptom persists, the pack may be the issue — a degraded cell delivers the rated voltage at rest but sags below 12V under motor load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-cycle then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a power failure. When suction is restricted — blocked filter, tangled brush roll, or the vacuum navigating thick carpet — the motor draws a sustained surge current. The BMS interprets that as a fault condition and cuts the output rail to protect the cells. After a few seconds, the BMS resets and allows the motor to restart. Clear the filter and inspect the brush roll for hair wrap before assuming the battery is at fault. If the cutouts continue on a clean machine, the existing pack's cells may no longer handle peak draw — replace the pack and retest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428089102426,"sku":"BWCS-IRB530VX-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428089135194,"sku":"BWCS-IRB530VX-2","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428089167962,"sku":"BWCS-IRB530VX-3","price":94.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB530VX-1.webp?v=1779934037","url":"https:\/\/batteryweb.com\/products\/auto-cleaner-intelligent-floor-vac-m-488-replacement-battery-144v-2800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
