It fits the AEG BFL 18, BHO 18, BKS 18, BMS 18C, and more than ten additional 18V AEG cordless tools sharing the same slide-rail connector and BMS communication protocol. Voltage and cell count match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCross-platform AEG 18V compatibility:\u003c\/strong\u003e\n    The BFL 18, BHO 18, BKS 18, and BMS 18C all run the same 18V rail with an identical battery connector and BMS handshake signal. One pack covers the entire platform — no adapter or firmware difference between models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack on an AEG BKS 18 circular saw through repeated motor-start inrush events. The BMS held stable across high-draw cuts and logged no false overcurrent trips during normal trigger operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in procedure for drill and saw use:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before full torque or full-depth cuts. This allows the BMS to profile the motor inrush current draw and set overcurrent thresholds before you hit peak demand.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS cutoff on motor-start inrush surge during trigger pull\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a drill or saw, the motor draws a brief inrush current that can be three to five times the running load. On a new pack, the BMS has no prior cycle history to calibrate its overcurrent threshold against. If the threshold is set too conservatively from the factory, the BMS trips and cuts power before the motor reaches speed. Running two half-load break-in cycles lets the BMS log real inrush data and adjust its trip point accordingly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows blinking red and never accepts the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAEG 18V chargers reject packs where cell voltage has dropped below the charger's acceptance threshold — typically around 2.5V per cell — during storage. The charger reads the low voltage as a damaged or deeply discharged pack and refuses to start a full charge cycle. To recover the pack, some AEG chargers have a wake-up or recovery mode — consult your charger manual for the recovery sequence, or look for a dedicated recondition button. If no recovery mode is available, verify cell voltage with a multimeter; a reading above 2.5V per cell means the charger itself may need a firmware update.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416010063962,"sku":"BWCS-RDD841PW-1","price":140.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416010096730,"sku":"BWCS-RDD841PW-2","price":166.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416010129498,"sku":"BWCS-RDD841PW-3","price":185.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RDD841PW-1.webp?v=1779759304","url":"https:\/\/batteryweb.com\/products\/aeg-bfl-18-replacement-battery-18v-6000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
