It fits the BS 12 G, BS 12X, BSB 12 G, BSB 12 STX, and more than a dozen additional AEG 12V models sharing the same battery slot geometry and contact layout. OEM part numbers covered include B1215R, B1220R, M1230R, and 0700 980 320.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e12V AEG drill platform fit:\u003c\/strong\u003e\n    The BS 12 G, BSB 12 G, and BSB 12 STX all run the same 12V battery rail with an identical slide-in connector and contact pin spacing. AEG kept this footprint consistent across the range, so one battery covers the full group without adapter plates or pin modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the BS 12 G platform. The BMS held charge acceptance normally, current draw on the motor-start inrush stayed within cutoff thresholds, and cell temperature under sustained load remained within the Ni-MH operating window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH first-cycle conditioning:\u003c\/strong\u003e\n    On first use, run the drill at half load for two cycles before full-torque applications. This lets the BMS profile the motor inrush current draw and calibrate its overcurrent protection 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 overcurrent trip on motor-start inrush in the BS 12 G\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a stalled or heavily loaded bit, the motor draws a short inrush spike well above its running current. On a new or recently stored Ni-MH pack, the BMS may not yet have a current profile for this drill's motor and can trip the overcurrent protection prematurely. Running two light-load cycles first gives the BMS enough data points to set the correct trip threshold. After conditioning, the pack handles the inrush without shutting down mid-fastening.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after extended storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells that have sat unused will self-discharge over time. If the pack voltage drops below the charger's acceptance threshold — typically around 10.5V for a 12V Ni-MH pack — the charger won't initiate a full charge cycle and may show no activity or a fault indicator. To recover the pack, use a charger that supports a trickle or recovery mode, which applies a low current to bring the cell voltage back above the acceptance floor. Once the pack reads above threshold, the normal charge cycle will start and the pack will accept a full charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416062459994,"sku":"BWCS-ABM215PW-1","price":82.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416062492762,"sku":"BWCS-ABM215PW-2","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416062525530,"sku":"BWCS-ABM215PW-3","price":107.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ABM215PW-1.webp?v=1779760039","url":"https:\/\/batteryweb.com\/products\/aeg-bs-12-g-replacement-battery-12v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
