It fits the MC-8R76C, MC-8R76D, MC-RS753, and MC-RS755 models. The battery matches the OEM voltage rail and connector so the vacuum's motor controller reads it as a valid pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMC-8R76C, MC-8R76D, MC-RS753, MC-RS755 fitment:\u003c\/strong\u003e\n    These four models share the same battery bay geometry, 14.4V motor rail, and BMS handshake protocol. One battery cell fits all four without adapter modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge on the MC-8R76C platform. The BMS engaged correctly at both ends — no false low-battery cutoffs and no overcharge trips at the charger termination point.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on this vacuum:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. These Panasonic models continue drawing a trickle current after the pack is full. Remove the vacuum from the dock once charging is complete to prevent accelerated capacity loss over time.\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 shows low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe MC-8R76C motor draws higher current under restricted airflow — a partially blocked filter forces the motor to work harder than its rated load. That surge in draw causes voltage to sag at the cell level, triggering a power reduction before the battery gauge registers as low. The vacuum reads this as a battery issue, but the actual problem is upstream. Clean or replace the filter, and the motor current returns to normal draw across a full charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean then recovering after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failing battery. When suction is blocked — by a clog, a dense carpet pile, or a full dust bin — the motor spikes beyond the BMS current threshold and the pack shuts output to protect the cells. The pack recovers once current demand drops and internal temperature falls. Clear the blockage, empty the bin, check the filter, then restart. If the cutout happens on an unobstructed floor, check that the replacement pack voltage is stable above 12.5V at rest before assuming a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427985817690,"sku":"BWCS-PMR760VX-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427985850458,"sku":"BWCS-PMR760VX-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427985883226,"sku":"BWCS-PMR760VX-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMR760VX-1.webp?v=1779933649","url":"https:\/\/batteryweb.com\/products\/panasonic-mc-8r76c-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
