It slots into the same battery bay as the original and connects to the same charging circuit. When the original cell loses capacity and the vacuum no longer holds a useful charge, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e488A and A3 compatibility:\u003c\/strong\u003e\n    Both models run the same 14.4V power rail, use the same battery bay dimensions, and share the same connector orientation — one battery covers both platforms without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on a 488A unit. The BMS accepted the charge handshake immediately, and discharge current held steady under motor load without triggering overcurrent cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the 488A:\u003c\/strong\u003e\n    Leaving a Ni-MH cell on continuous dock charge accelerates capacity fade. Charge the vacuum fully, then remove it from the dock. Reconnect only when the battery is depleted. This matters more for Ni-MH chemistry than lithium cells.\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 488A\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the battery can deliver at its present state of charge, causing voltage to sag under load before the cell is actually depleted. On the 488A, a partially blocked filter makes this worse — restricted airflow forces the motor to work harder, pulling higher current and triggering voltage sag earlier. The battery indicator reads state of charge at rest, not under load, so it lags behind what you feel in suction. Clean the filter first, then test — if sag continues, the cell is the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use and then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained suction restriction forces the motor to draw above the BMS threshold — typically from a blocked filter or full dustbin — the protection circuit opens and cuts power. The pause allows the BMS to reset and the cell temperature to stabilise. Clear the filter and empty the bin before assuming the battery is faulty. If trips continue on a clean, unrestricted machine, the replacement cell's BMS threshold may need a full charge cycle to recalibrate — charge to 100% and retest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428087726170,"sku":"BWCS-IRB400VX-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428087758938,"sku":"BWCS-IRB400VX-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428087791706,"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\/vileda-488a-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
