It fits the 1010FK, EP750, EP750M, and EP750ST models. OEM part number X8901 cross-references directly to these units.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEP750 and 1010FK platform fit:\u003c\/strong\u003e\n    These models share the same 15.6V battery architecture, connector housing, and BMS communication protocol — which is why one cell covers the full range. Swapping between models in this group carries no electrical risk.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on an EP750 unit. The BMS handshake completed cleanly, the charger accepted the pack without fault codes, and current draw tracked within spec under sustained suction load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on the EP750 range:\u003c\/strong\u003e\n    Do not leave this vacuum on the charging dock permanently. Ni-MH cells in continuous trickle charge degrade faster than those charged only when depleted. 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\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eOn the EP750 series, suction loss often happens well before the battery light signals low charge. The motor in these hand vacuums draws more current when the filter is partially blocked — this pulls the cell voltage down faster than normal discharge would. The BMS reads the voltage sag and begins throttling power to the motor as a protective measure. Clean or replace the filter first before assuming the battery is the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use, then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When restricted airflow forces the motor to work harder, current draw spikes past the BMS threshold and the pack shuts output temporarily. The BMS resets once current drops, which is why the vacuum restarts on its own. Check the filter and the nozzle path for blockages before the next use — if the filter is clear and trips continue, measure resting pack voltage; anything below 14.0V after a full charge indicates cell degradation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428021436506,"sku":"BWCS-SHP750VX-1","price":79.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428021469274,"sku":"BWCS-SHP750VX-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428021502042,"sku":"BWCS-SHP750VX-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHP750VX-1.webp?v=1779933917","url":"https:\/\/batteryweb.com\/products\/shark-1010fk-replacement-battery-156v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
