It fits the V2945, V2945Z, V2950, and V2950A models. The OEM part number is XB2950.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eV2945 and V2950 platform compatibility:\u003c\/strong\u003e\n    These models share the same 7.2V Ni-MH battery architecture, connector layout, and BMS communication protocol. Swapping the XB2950 between them works because the voltage rail and cell format are identical across that generation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on V2950-series hardware. The BMS accepted the cell pack without fault codes, held voltage through the full discharge curve, and cut off cleanly at the low-voltage threshold without triggering a hard fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging practice for Ni-MH cells:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock between uses. Ni-MH cells degrade faster under continuous trickle charge than they do from normal cycle use. Charge to full, then remove from the dock until the next use.\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 draws more current than the cell pack can deliver at a stable voltage — the pack voltage sags under load before the indicator logic registers a low-battery condition. On Ni-MH cells, this gets worse as the pack ages because internal resistance rises with cycle count. A partially blocked filter makes it worse by forcing the motor to work harder. Clear the filter first, then check whether the pack holds above 6.5V under load using a multimeter at the battery terminals.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out and then recovering mid-clean\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained suction restriction — from a clogged filter, blocked nozzle, or heavy carpet — forces the motor to pull current above the BMS threshold, the BMS disconnects the cell pack momentarily to protect the cells. Power returns once current demand drops. Clean the filter thoroughly and check the nozzle for blockage. If the motor still cuts out on a clean machine, the cell pack's capacity has degraded enough that its internal resistance is driving the overcurrent condition — replacing the pack resolves it.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428046307418,"sku":"BWCS-EXV295VX-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428046340186,"sku":"BWCS-EXV295VX-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428046372954,"sku":"BWCS-EXV295VX-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-EXV295VX-1.webp?v=1779933938","url":"https:\/\/batteryweb.com\/products\/shark-v2945-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
