It fits the 900257877, ERV7210TG, ERV7200DB, 900257983, and over 28 additional models that share the OSBP72LI25 battery specification. Capacity figures come from the product data — 18.72Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eERV7210TG and 900257877 platform compatibility:\u003c\/strong\u003e\n    These models share a common 7.2V motor rail and the same BMS handshake protocol. The connector and cell configuration are identical across the cluster, which is why one pack covers such a wide model range.\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 ERV7210TG platform. The BMS engaged correctly at low-voltage cutoff and accepted a full charge without tripping the protection circuit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on stick vacuums:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock permanently. Continuous dock charging causes capacity fade significantly faster than charging only when the pack is 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  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not a capacity failure. When the filter is partially blocked or the brush roll is restricted, the motor draws more current than rated. The pack voltage drops under that load spike, and the motor slows — even though the indicator still shows charge remaining. Clean the filter and check the brush roll for hair wrap before replacing the battery. A healthy pack at rest should read 8.1–8.4V off the charger.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cutting out mid-clean and then recovering after a pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked filter, clogged cyclone, or a full dust cup — the motor labours and draws sustained high current. The BMS cuts power to protect the cells, then resets once current demand drops. Clear the blockage completely, then restart the vacuum. If it trips again on a clean filter, the cells may have aged below the point where they can sustain motor-start current.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426458173530,"sku":"BWCS-AGP726VX-1","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426458206298,"sku":"BWCS-AGP726VX-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426458239066,"sku":"BWCS-AGP726VX-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AGP726VX-1.webp?v=1779933287","url":"https:\/\/batteryweb.com\/products\/electrolux-900257877-replacement-battery-72v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
