It fits the AP1172, AP1172N, and V1917 models. Voltage and capacity match the original pack specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAP1172, AP1172N, V1917 compatibility:\u003c\/strong\u003e\n    These three models share the same 8.4V cell stack, connector pinout, and physical housing dimensions. A single replacement pack covers all three without modification.\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 a V1917 unit. The BMS held voltage steady under normal carpet suction load and triggered protection correctly when current exceeded the rated draw threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on this vacuum:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock between uses. The AP1172 series dock does not cut charge when full — continuous trickle current degrades Ni-MH cells faster than any other single factor. 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 AP1172\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs lose voltage under motor load before the open-circuit voltage drops enough to trigger the low-battery indicator. On the AP1172, this means suction noticeably weakens while the indicator still shows adequate charge. A restricted filter makes this worse — the motor draws higher current to maintain suction, and the pack voltage sags further under that extra load. Clean or replace the filter first, then check whether the issue persists with a fresh battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean 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 the vacuum filter is partially blocked, the motor works harder to pull airflow, drawing more current than the BMS allows for sustained periods. The protection circuit cuts power, and the pack recovers once current demand drops. Clearing the filter is the first fix — if the cut-out continues on a clean filter with a new pack, check that the motor brush contacts are seated correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428049289306,"sku":"BWCS-EPA117VX-1","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428049322074,"sku":"BWCS-EPA117VX-2","price":89.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428049354842,"sku":"BWCS-EPA117VX-3","price":98.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EPA117VX-1.webp?v=1779933938","url":"https:\/\/batteryweb.com\/products\/euro-pro-ap1172-replacement-battery-84v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
