It matches the OEM part number INR18650-25R and fits directly into the H3's battery compartment. Order this when the original cell no longer holds charge or the vacuum loses suction well before the indicator shows low.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eH3 platform fit:\u003c\/strong\u003e\n    The H3 uses a compact 7.4V two-cell Li-ion pack at this exact form factor. The BMS on this replacement matches the voltage rails and discharge curve the H3 motor controller expects — 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 H3 motor circuit. The BMS held cutoff cleanly at low-cell voltage and did not trip during the motor's start-up current draw.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on the H3:\u003c\/strong\u003e\n    Remove the H3 from its charging dock once the battery reaches full. Cordless vacuums left continuously docked receive a low-level trickle charge that accelerates capacity fade — this shortens the usable life of the new cell faster than regular cycling does.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSuction dropping on the H3 before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag symptom, not always a dead battery. When the H3 motor draws current under load — particularly on carpet or through a partially blocked filter — cell voltage dips below what the motor controller expects. The controller responds by reducing power output, which reads as suction loss. A degraded original cell sags far earlier in its discharge curve than a fresh pack. Replacing the cell restores the flat voltage curve the H3 needs to hold consistent suction through a full clean.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eH3 motor 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 faulty motor. When airflow is restricted — by a clogged filter or a blockage in the nozzle — the motor works harder and pulls more current than the BMS allows. The BMS shuts the circuit to protect the cell, then resets after a short cooldown. Clear the filter and check the nozzle path first. If the cut-out stops after cleaning the filter, the battery was not the cause — but if it continues with an unobstructed path on a new cell, check that cell voltage under load sits above 6.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426375729242,"sku":"BWCS-MDH300VX-1","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426375762010,"sku":"BWCS-MDH300VX-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426375794778,"sku":"BWCS-MDH300VX-3","price":74.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MDH300VX_1.webp?v=1779931027","url":"https:\/\/batteryweb.com\/products\/midea-h3-replacement-battery-74v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
