It replaces OEM part S00001987 directly. The battery slots into the same bay and connects to the same BMS handshake points as the original cell pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAE2529 and AE2529 2JG coverage:\u003c\/strong\u003e\n    Both models run the same 29.6V Li-ion pack with an identical connector and BMS communication protocol. The voltage rail, pin layout, and charge cutoff logic are shared across the two variants, so one replacement cell covers both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through full charge and discharge runs on the AE2529 motor platform. The BMS held steady cutoff at the correct lower voltage threshold without nuisance trips, and the charger handshake completed normally on every cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eDock charging behaviour on the AE2529:\u003c\/strong\u003e\n    Do not leave this vacuum sitting on the charging dock permanently. Continuous dock charge on Li-ion packs causes measurable capacity fade over weeks — faster than normal cycle wear. Charge to full, then remove 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 reaches low on the AE2529\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a voltage sag issue, not a capacity problem. When the filter is partially blocked or the floor nozzle is restricted, the motor draws above its rated current to maintain airflow. That excess draw pulls the pack voltage down faster than the indicator registers. The battery indicator reads state of charge at rest voltage — it lags behind the real-time sag under load. Clean the filter and check the nozzle for blockage first; if suction recovers fully, the battery is fine.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAE2529 motor cuts out mid-clean then recovers after a few seconds\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis is a BMS overcurrent trip, not a failed battery. A sustained blockage — blocked filter, jammed brush roll, or sealed nozzle — forces the motor to pull current beyond the BMS protection threshold. The BMS disconnects the output to protect the cells, then resets once current demand drops. The fix is to clear the restriction: remove the filter and tap it clean, check the brush roll for hair wrap, and verify the nozzle pathway is clear. If the motor runs without cutting out after that, the pack is operating correctly.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426381201498,"sku":"BWCS-SAE259VX-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426381234266,"sku":"BWCS-SAE259VX-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426381267034,"sku":"BWCS-SAE259VX-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SAE259VX-1.webp?v=1779931027","url":"https:\/\/batteryweb.com\/products\/solac-ae2529-replacement-battery-296v-3500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
