It replaces the original cell when the factory pack no longer holds enough charge to complete a cleaning run. Capacity is rated at 2000mAh (28.8Wh), matching the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eX500, X580, and KK8 compatibility:\u003c\/strong\u003e\n    These three models share the same 14.4V battery rail, connector footprint, and motor control circuit. The same pack fits all three without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the X500 motor assembly. The BMS responded correctly to both motor-start inrush current and sustained suction load without tripping or throttling output.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on cordless vacuums:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. Ni-MH cells in continuous trickle charge degrade significantly faster than cells charged only when depleted. Charge to full, then remove 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\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the motor draws more current than the pack's internal resistance can sustain cleanly — voltage sags under load even though state-of-charge still reads normal. A partially blocked filter makes it worse because the motor works harder against restricted airflow, pulling the pack voltage down faster. The battery indicator measures resting voltage, not load voltage, so it lags behind what the motor is actually seeing. Clean the filter first, then retest suction under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and recovering after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is blocked — clogged filter, tangled brush roll, or a hard carpet pile — the motor current spikes past the BMS threshold and the pack shuts output to protect the cells. After a few seconds the BMS resets and power returns. The fix is to clear the restriction before the next run. If it trips on a clean, unblocked floor, check that pack voltage at rest sits above 13.0V before starting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428063019098,"sku":"BWCS-ECR120VX-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428063051866,"sku":"BWCS-ECR120VX-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428063084634,"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\/dibea-x500-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
