It slots into the robot's battery bay and restores autonomous cleaning cycles once the original cell has degraded. Capacity figure is taken directly from product data.\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 motor rail with a Ni-MH BMS that monitors cell temperature and voltage during charge. Swapping to the same chemistry keeps the charge controller's cutoff thresholds valid and avoids false overcharge events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the M-288's onboard charger and confirmed the BMS completed a full charge cycle without triggering thermal cutoff. Discharge tracking matched the vacuum's low-battery indicator at the expected voltage threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the M-288:\u003c\/strong\u003e\n    Do not leave the M-288 sitting on the charging dock permanently. Ni-MH cells in continuous dock contact receive a trickle current that accelerates capacity fade. Charge to full, then remove the vacuum from the dock until the next cleaning cycle.\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 M-288 battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA partially blocked filter forces the M-288's motor to draw current above its rated load. Ni-MH cells respond to sustained overcurrent with accelerated voltage sag, so suction weakens well before the indicator triggers. The battery is not always the cause — check the filter first. Clean or replace the filter, then retest; if suction holds across a full cycle, the cell is likely fine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eM-288 motor cuts out mid-cycle and then restarts on its own\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the M-288 transitions from hard floor to thick carpet, motor-start current spikes sharply. If the filter is restricted at the same time, the combined draw can breach the BMS threshold and cut power. The BMS resets once current drops, which is why the vacuum appears to recover. Clear the filter, confirm no brush-roll blockage, and check that cell voltage at rest reads at least 13.0V before concluding the battery is the fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428088217690,"sku":"BWCS-IRB400VX-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428088250458,"sku":"BWCS-IRB400VX-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428088283226,"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\/robotic-smart-vacuum-cleaner-m-288-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
