It slots into the existing battery compartment and works with the original charging dock. Capacity is 1300mAh (15.6Wh) — matched to the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAG901 and AG902 platform fit:\u003c\/strong\u003e\n    These models share the same 12V battery rail, connector geometry, and BMS handshake across the range. One cell fits the full compatibility list without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles on the AG901 platform. The BMS accepted the replacement without fault flags, and the charge dock terminated correctly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging discipline:\u003c\/strong\u003e\n    Do not leave this vacuum on the charging dock permanently. Ni-MH cells in cordless vacuums develop measurable capacity fade from continuous trickle charge. 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\"\u003eOn the AG901 and AG902, the motor draws significantly more current when the filter is partially blocked. That elevated draw causes voltage to sag at the cell earlier than the indicator circuit expects, so suction weakens while the LED still shows adequate charge. The battery is not the root cause — the motor is simply pulling past its rated current. Check and clean the filter first. If suction restores after a clean filter, the cell is functioning correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMotor cuts out mid-use and then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a dead battery. When sustained restricted airflow forces the motor to spike current draw, the BMS cuts the output to protect the cell, then resets once temperature and current drop. It feels like a failing battery but the cell voltage at rest will read above 12V after recovery. Clear any blockage in the nozzle or hose and confirm the filter is clean. If the cutout stops after clearing the restriction, the replacement cell is operating as expected.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43428033462362,"sku":"BWCS-ELB290VX-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43428033495130,"sku":"BWCS-ELB290VX-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43428033527898,"sku":"BWCS-ELB290VX-3","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ELB290VX-1.webp?v=1779933938","url":"https:\/\/batteryweb.com\/products\/aeg-900165577-replacement-battery-12v-1300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
