It replaces OEM part VBHC7787E and cross-references 8087979053, 809115702, and related AEG part numbers. Swap it in when the original cell no longer holds enough charge to complete a cleaning session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e900273716 and AG-series platform fit:\u003c\/strong\u003e\n    These AEG vacuums share a common 18V bus, BMS handshake protocol, and battery connector across the 900273716, 900273717, AG3013, and AG18 Plus range — one cell format covers the group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell under sustained suction load and confirmed the BMS holds the 18V rail steady through normal carpet and hard-floor draw cycles without tripping an overcurrent cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline for AEG stick vacuums:\u003c\/strong\u003e\n    Do not leave this vacuum on the charging dock permanently. AEG cordless vacuums left on continuous dock charge develop capacity fade significantly faster than those charged only when depleted. Charge to full and 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 happens when the motor draws more current than the BMS expects — usually because a partially blocked filter forces the motor to work harder. The BMS reads the elevated draw as a low-voltage condition and begins throttling output before the indicator has a chance to catch up. The fix is filter-side, not battery-side: clean or replace the filter and the voltage sag disappears. If the problem continues on a clean filter, check the cell voltage at rest — a healthy cell should sit at or above 20V fully charged.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use then restarts after a short pause\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed battery. It happens when sustained restricted airflow — from a clogged filter or blocked nozzle — causes the motor to spike current beyond the BMS threshold. The BMS shuts the cell off to protect it, then resets once temperature drops and current normalises. Clear the blockage at the nozzle or filter first. If the cutout persists on an unobstructed machine, measure cell voltage under load — it should not drop below 15V during normal operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428008624218,"sku":"BWCS-ELT320VX-1","price":62.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428008656986,"sku":"BWCS-ELT320VX-2","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428008689754,"sku":"BWCS-ELT320VX-3","price":82.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ELT320VX-1.webp?v=1779933824","url":"https:\/\/batteryweb.com\/products\/aeg-900273716-replacement-battery-18v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
