It fits multiple models including the BDCD112, BDCDD12KB, and BDCDD12K. Voltage, connector, and BMS communication match the original pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBDCDD12 platform compatibility:\u003c\/strong\u003e\n    These models share the same 12V battery rail, slide-in connector, and BMS handshake protocol. The same pack works across BDCDD12, BDCD112, BDCDD12KB, and BDCDD12K without any adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through trigger-pull cycles on a BDCDD12 and monitored the BMS under repeated motor-start inrush. The overcurrent protection responded within spec, and the pack held its voltage rail through sustained fastening sequences.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush break-in:\u003c\/strong\u003e\n    On first use, run the drill at half load for two cycles before applying maximum torque. This lets the BMS profile the motor inrush current draw before it finalises overcurrent protection thresholds — reducing the chance of a nuisance trip on hard starts.\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 BDCDD12 motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger hard into a tough fastener, the motor draws a sharp current spike before it reaches operating speed. On a 12V pack, this inrush can briefly exceed 15–20A. If the BMS has not yet profiled the motor load — or if the cells are cold — it reads the spike as an overcurrent fault and cuts the output rail. The tool goes dead mid-use, then recovers after a second or two once the BMS resets.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red and refusing to accept the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs that have sat in storage can drop below the charger's minimum acceptance voltage — typically around 9V on a 12V pack. The charger sees the low cell voltage and flags it as a fault rather than starting a charge cycle. Remove the pack, wait 60 seconds, and re-seat it firmly to trigger a fresh handshake. If the charger still blinks red, check that each cell group is above 2.5V using a multimeter at the pack terminals before concluding the pack is faulty.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416020844634,"sku":"BWCS-BDX512PX-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416020877402,"sku":"BWCS-BDX512PX-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416020910170,"sku":"BWCS-BDX512PX-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BDX512PX-1.webp?v=1779759461","url":"https:\/\/batteryweb.com\/products\/black-decker-bdcdd12-replacement-battery-12v-2500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
