It slots into the original battery housing and restores power to the motor without replacing the whole unit. 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 X600 compatibility:\u003c\/strong\u003e\n    These three models share the same 14.4V battery rail, connector pinout, and housing dimensions. Swapping between them is straightforward because the BMS charge and discharge thresholds are identical across the range.\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 a Panda cordless vacuum motor assembly. The BMS held cutoff voltage correctly and the cell delivered consistent output without voltage sag under normal suction load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging habit on Ni-MH cells:\u003c\/strong\u003e\n    Do not leave the vacuum sitting on the charging dock permanently. Ni-MH chemistry degrades significantly faster under continuous trickle charge. Charge to full, then remove the unit 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 shows low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is one of the most common complaints on the X500 and X580. The battery indicator reads mid-range, but suction noticeably weakens — especially on carpet or rugs. A partially blocked filter forces the motor to draw more current than rated, which causes voltage to sag under load even when cell capacity is not fully depleted. The result is reduced motor speed and weaker airflow with no low-battery warning. Clean or replace the filter first before assuming the battery is the cause.\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 flat battery. When suction is restricted — blocked nozzle, saturated filter, or carpet pile jamming the brush roll — the motor draws a sustained current spike above the BMS threshold. The BMS shuts the cell output to protect the battery, which reads as the vacuum switching off. After a short pause the BMS resets and the motor restarts. Clear the blockage and check the filter before assuming the battery needs replacement. If the trip repeats on a clean machine, measure resting cell voltage — a healthy Ni-MH pack at full charge should sit between 16.8V and 17.2V across the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428064034906,"sku":"BWCS-ECR120VX-1","price":57.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428064067674,"sku":"BWCS-ECR120VX-2","price":66.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428064100442,"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\/panda-x500-replacement-battery-144v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
