It replaces the original CND 4S1P cell pack when the existing battery can no longer hold a useful charge. Swap it in to restore cordless cleaning power without replacing the entire unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eExcellenza platform fit:\u003c\/strong\u003e\n    The Excellenza runs a 14.4V motor rail with a Ni-MH cell pack — a chemistry the onboard charging circuit is tuned to handle. The CND 4S1P pack matches that voltage rail and connector geometry, so the charger communicates with the replacement pack the same way it did with the original.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and load sequences on the Excellenza platform. The BMS held cutoff cleanly at low-cell voltage during sustained suction loads, and the charger terminated at full capacity without overcharge events.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on Ni-MH cells:\u003c\/strong\u003e\n    Do not leave the Excellenza sitting on the charging dock continuously between uses. Ni-MH cells degrade faster under constant trickle charge than lithium chemistries do. Charge to full, then remove the vacuum 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 on the Excellenza\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Excellenza motor pulls harder when airflow is restricted — a clogged filter or partial blockage forces the motor to draw above its rated current even on a full pack. That elevated draw causes voltage sag across the Ni-MH cells, and the motor slows before the battery indicator registers low. The indicator measures resting cell voltage, not load voltage, so it lags behind what the motor is actually seeing. Clean or replace the filter first, then check whether suction holds steady across a full charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-clean and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip — the protection circuit detects a sustained current spike above safe limits and shuts the motor down temporarily. On the Excellenza, this usually happens when suction is restricted: a blocked filter or full dust cup forces the motor to work harder, spiking draw. The BMS resets itself once current drops, which is why the vacuum recovers after a brief pause. Clear the dust cup, check the filter condition, and confirm the pack reads at least 14.4V resting before writing off the battery.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428003938394,"sku":"BWCS-PRC950VX-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428003971162,"sku":"BWCS-PRC950VX-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428004003930,"sku":"BWCS-PRC950VX-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRC950VX-1.webp?v=1779933849","url":"https:\/\/batteryweb.com\/products\/ursus-trotter-excellenza-replacement-battery-144v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
