It slots into the same bay as the original pack and powers the vacuum motor for floor and carpet cleaning. Capacity figure is 3000mAh (43.2Wh), taken from the product specification — not extrapolated from runtime claims.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEP750 and EP750 100350 compatibility:\u003c\/strong\u003e\n    Both variants run the same 14.4V motor rail with the same connector pinout and BMS handshake. One battery pack covers both units — no modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the EP750 platform. The BMS held the voltage rail steady under simulated carpet-load draw and tripped at the correct low-voltage cutoff without nuisance shutdowns.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for Ni-MH cells:\u003c\/strong\u003e\n    Do not leave the EP750 sitting on the charging dock after the pack reaches full charge. Ni-MH chemistry is particularly sensitive to continuous trickle current — capacity fade accelerates significantly faster than with intermittent charging. Charge to full, then remove from 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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells show a characteristic mid-discharge voltage sag when the motor is under sustained load — most noticeable on thick carpet. The EP750 motor draws higher current through restricted airflow, which pulls cell voltage down faster than the indicator circuit expects. The result is noticeably weaker suction while the indicator still reads mid-range. Clean or replace the foam and felt filters first — restored airflow reduces peak draw and the voltage sag flattens out.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the EP750 filter is partially blocked, the motor works against restricted airflow and draws current above the BMS threshold. The pack shuts output to protect the cells, then resets once temperature and current stabilise — usually within 30 to 60 seconds. Clearing the filter blockage is the fix. If cutouts continue on a clean filter, check that cell voltage at rest is at or above 14.4V before ruling out a worn pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428080812122,"sku":"BWCS-ERF750VX-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428080844890,"sku":"BWCS-ERF750VX-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428080877658,"sku":"BWCS-ERF750VX-3","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ERF750VX-1.webp?v=1779934015","url":"https:\/\/batteryweb.com\/products\/shark-ep750-replacement-battery-144v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
