It slots into the same battery bay and connects to the same BMS circuit as the original. Capacity is rated at 37.44Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMulti-model fit across the MC-RS877 platform:\u003c\/strong\u003e\n    The MC-RS877, MC-6RB75, RS767, and WRC76 share the same 14.4V voltage rail, connector pinout, and BMS communication protocol — which is why a single replacement pack covers all of them without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Panasonic charger handshake and confirmed the BMS negotiated charge termination correctly at full capacity. Discharge curves held flat across the motor's working load range with no premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habits matter on this platform:\u003c\/strong\u003e\n    Do not leave the MC-RS877 sitting on its charging dock continuously between runs. Cordless robotic vacuums on permanent dock charge develop capacity fade significantly 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  \u003cp class=\"bpw-desc-p\"\u003eOn the MC-RS877, the motor draws harder when airflow is restricted — a partially blocked filter forces the motor to pull more current than the BMS expects at that state of charge. The BMS interprets this elevated draw as a low-cell condition and begins throttling motor power, which the user reads as suction loss. The battery still has charge remaining; the motor is just being starved to protect the cell. Clean or replace the filter first, then test — if suction holds steady to a lower charge level, the filter was the cause.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-run and then recovering after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When the MC-RS877 hits a sustained blockage — thick carpet pile, debris buildup at the intake — the motor load spikes and the BMS cuts the circuit to protect the cell. The unit recovers after a short rest because the BMS resets once current demand drops. Clear the intake path and check that the brush roll spins freely. If the cutout happens again on clear floors, measure resting cell voltage — it should sit above 12.5V between runs.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43427992240218,"sku":"BWCS-PMR877VX-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43427992272986,"sku":"BWCS-PMR877VX-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43427992305754,"sku":"BWCS-PMR877VX-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMR877VX-1.webp?v=1779933755","url":"https:\/\/batteryweb.com\/products\/panasonic-mc-rs877-replacement-battery-144v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
