It fits the SWR-T320, SWR-T321, SWR-T322, and SWR-T325 handheld vacuum models. Swap it when your original cell no longer holds a charge or suction weakens well before the battery indicator drops.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSWR-T320 series fit:\u003c\/strong\u003e\n    The T320, T321, T322, and T325 share the same 14.4V battery bay, connector pinout, and BMS communication protocol. One cell covers all four variants without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through full charge and discharge cycles on the SWR-T320 platform. The BMS handshake completed correctly, charge acceptance was normal, and the motor drew within rated current at full suction load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on Haier stick vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock between uses. The Haier dock applies a continuous trickle current after reaching full charge. Ni-MH cells degrade faster under sustained trickle than they do from regular full discharge cycles. Charge to full, then remove it.\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 carpet before the battery indicator reaches low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the SWR-T320 series, carpet fibres and fine dust restrict the filter faster than hard floor use. A partly blocked filter forces the motor to work harder, drawing current above its rated load. The BMS reads the spike as a low-cell-voltage event and throttles motor power to protect the pack — suction drops even though the battery still shows charge. Clear the filter and check the brush roll for hair wrap before blaming the battery.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained suction restriction pushes current draw beyond the pack's protection threshold, the BMS opens the discharge circuit and the motor stops. Waiting 30–60 seconds lets the BMS reset and the motor restarts. The fix is upstream — clear any blockage in the nozzle, hose, or filter so current draw drops back inside the BMS window. If trips continue on a clear vacuum, verify cell voltage sits above 12V at rest before ruling out a worn pack.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428063838298,"sku":"BWCS-ECR120VX-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428063871066,"sku":"BWCS-ECR120VX-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428063903834,"sku":"BWCS-ECR120VX-3","price":73.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ECR120VX-1.webp?v=1779934014","url":"https:\/\/batteryweb.com\/products\/haier-swr-t320-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
