It slots into the same battery compartment as the original cell and connects to the same motor driver board. Capacity is rated at 43.2Wh — matching the factory specification for this vacuum series.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e488A and A3 platform compatibility:\u003c\/strong\u003e\n    Both models share the same 14.4V motor rail, battery bay dimensions, and connector pinout. A single cell covers both without modification or adapter.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full charge and discharge runs on the 488A motor board. The BMS held voltage steady under sustained suction load and cut off cleanly at the low-cell threshold without tripping the overcurrent rail prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock continuously. Ni-MH cells in cordless vacuums develop capacity fade significantly faster under constant trickle charge. Charge to full, then remove from the dock until the next use.\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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells under load show a voltage curve that sags early when the cell is aged or the filter is partially blocked. The motor draws more current trying to maintain airflow, which pulls the cell voltage down faster than the indicator circuit expects. The indicator reads state-of-charge from resting voltage — not real-time load voltage — so it lags behind what the motor actually sees. Clean or replace the filter first, then recharge fully; if suction still drops early, the cell is the likely cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use 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 the filter is restricted or the pickup head is partially blocked, the motor draws sustained high current to compensate. The BMS reads this as an overcurrent event and shuts the output rail to protect the cell. After a brief pause the BMS resets and power returns. Clear the blockage, check the filter for compacted debris, and recharge the cell before the next run — sustained overcurrent trips accelerate cell degradation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428054335578,"sku":"BWCS-IRB410VX-1","price":91.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428054368346,"sku":"BWCS-IRB410VX-2","price":106.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428054401114,"sku":"BWCS-IRB410VX-3","price":118.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-IRB410VX-1.webp?v=1779933966","url":"https:\/\/batteryweb.com\/products\/vileda-488a-replacement-battery-144v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
