It fits the T350G, T320, R320, T350B, and 13 additional models that share the same voltage rail and battery housing. When the original cell degrades and suction drops off quickly, this replacement restores the vacuum to its factory power draw.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eT350G \/ T320 \/ R320 platform compatibility:\u003c\/strong\u003e\n    These models share a common 14.8V battery bay, BMS connector pinout, and charge handshake protocol. One cell services the entire range because the motor controller reads the same BMS signal regardless of which chassis it sits in.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on the T350G motor assembly under simulated floor and carpet load cycles. The BMS held the 14.8V rail steady through repeated surge draws at motor startup and did not trip at normal operating current.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging on Haier stick vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum seated on the charging dock permanently. Haier's dock delivers a trickle current once full charge is reached, and sustained trickle charging causes measurable capacity fade in lithium cells. Charge to full, then remove the vacuum 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\"\u003eCordless vacuum losing suction before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag problem, not always a dead battery. When the filter is partially blocked, the motor works harder and pulls more current than rated. That increased draw causes the cell's voltage to sag under load even when the indicator still shows charge remaining. The BMS reads the sag as a low-voltage condition and throttles output to protect the cell. Clean or replace the filter first — if suction recovers, the battery was not the fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a faulty cell. Sustained restricted airflow — from a clogged filter or blocked nozzle — forces the motor to draw above the BMS current threshold. The BMS shuts the output to protect the cell, then resets once current demand drops. The fix is clearing the restriction before replacing the battery. If the cutout persists on an unblocked vacuum with a clean filter, check that the terminal voltage under no-load sits above 14.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426443198554,"sku":"BWCS-HAR350VX-1","price":49.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426443231322,"sku":"BWCS-HAR350VX-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426443264090,"sku":"BWCS-HAR350VX-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAR350VX-1.webp?v=1779933287","url":"https:\/\/batteryweb.com\/products\/haier-t350g-replacement-battery-148v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
