It slots into the battery bay on the handle section and powers both the suction motor and the motorized brush head. Voltage and pack geometry match the OEM spec exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e271100-series platform fit:\u003c\/strong\u003e\n    These models share the same 14.4V rail, connector pinout, and BMS handshake protocol across the range. One pack covers the full compatibility list 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 charge and discharge cycles on a 271100-series unit. The BMS accepted the pack cleanly, thermal cutoff triggered at the correct threshold under a blocked-filter stress test, and the pack recovered to normal operation once the fault cleared.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on Ariete stick vacuums:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock permanently. Ariete's dock delivers a trickle charge once full — continuous trickle on Ni-MH cells accelerates capacity fade. Charge to full and remove the unit 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\"\u003eThis happens when the motor is drawing more current than the pack can sustain at full voltage — but the indicator hasn't triggered yet. A partially blocked filter is the most common cause. Restricted airflow forces the motor to work harder, pulling higher amps and causing the pack voltage to sag under load. Clean or replace the filter first, then test suction again at a measured 14.4V charge state before assuming the battery is at fault.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked brush head, clogged filter, or a rug fibre caught in the impeller — current draw spikes above the BMS threshold and the pack disconnects to protect the cells. After a few seconds the BMS resets and the vacuum runs again. Clear the blockage, check the brush roll for wrapped debris, and confirm the filter is clean before running the vacuum again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428019535962,"sku":"BWCS-ART271VX-1","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428019568730,"sku":"BWCS-ART271VX-2","price":93.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428019601498,"sku":"BWCS-ART271VX-3","price":103.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ART271VX-1.webp?v=1779933899","url":"https:\/\/batteryweb.com\/products\/ariete-271100aluk-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
