It fits the BBM 18 STX, BDSE 18 STX, BDSE 18 T Super Torque, BSB 18STX, and several other AEG 18V platform tools. OEM part references include B 18, BXL 18, BXS 18, MX 18, MXM 18, MXS 18, and Atlas Copco equivalents BX 18 and B 18.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAEG 18V platform fit:\u003c\/strong\u003e\n    These models share the same 18V slide-rail connector, cell-count configuration, and BMS handshake protocol. The pack slots directly into any tool on this platform without adapter modifications.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a BBM 18 STX through repeated motor-start cycles. The BMS responded correctly to inrush current spikes and did not trip false overcurrent events during normal trigger-pull sequences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in cycle for new Ni-MH packs:\u003c\/strong\u003e\n    Run the tool at half load for two full discharge-charge cycles before maximum torque applications. This lets the BMS map the motor inrush draw and calibrate its overcurrent thresholds before you push the pack hard.\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 in the BBM 18 STX\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a drill under load, current demand spikes sharply before the motor reaches speed. On Ni-MH packs that have been sitting unused, internal resistance rises and that spike can momentarily breach the BMS overcurrent threshold. The pack shuts off as a protection response — not a cell failure. Two break-in cycles at reduced load lower the effective inrush spike and keep the BMS from cutting out mid-task.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs down under sustained load but recovers at rest\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eVoltage sag under sustained load is a known Ni-MH behaviour — as current draw rises, terminal voltage drops below what the motor controller expects. If the tool slows noticeably during long screw-driving runs but recovers after a short rest, check the rail contacts first. Oxidised or dirty contacts add resistance and amplify sag. Clean the battery terminal rails with isopropyl alcohol and confirm contact pressure before assuming the cells are at fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416080056410,"sku":"BWCS-MKE180PW-1","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416080089178,"sku":"BWCS-MKE180PW-2","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416080121946,"sku":"BWCS-MKE180PW-3","price":135.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKE180PW-1.webp?v=1779760118","url":"https:\/\/batteryweb.com\/products\/aeg-bbm-18-stx-replacement-battery-18v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
