It fits the CCD12, CCD12v, CCD12ES, and CCD12ES-C, along with over 24 additional CCD12-series variants. The pack replaces OEM part numbers BP12C and BPH12C, along with cross-references including 487701, 488438, and 489728.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCCD12-series fit:\u003c\/strong\u003e\n    All CCD12 variants share the same 12V cell stack, connector pinout, and BMS communication protocol. Swapping cells or chemistry would break the handshake with Festool's charger, so this pack maintains the correct Ni-MH cell configuration the charger expects.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the Festool charger and confirmed full charge acceptance, correct charge termination via delta-V cutoff, and stable voltage delivery under repeated trigger pulls on the CCD12 platform.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in procedure for Ni-MH cells:\u003c\/strong\u003e\n    Run the CCD12 at half load for the first two cycles before applying full torque. This lets the BMS log the motor's inrush current pattern and set accurate overcurrent thresholds — skipping this step can cause premature cutoff 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 CCD12 motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe CCD12 motor pulls a sharp current spike the moment the trigger engages — easily three to five times the steady running draw. On a new or cold Ni-MH pack, the BMS has not yet profiled this inrush and may interpret it as a fault, cutting power before the motor reaches speed. Running two break-in cycles at half load trains the BMS to distinguish normal inrush from a genuine overcurrent event. After those cycles, full-torque applications on wood, metal, and plastic should trip no cutoffs.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDrill bogs under load even with a charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eVoltage sag under sustained load on a Ni-MH pack usually points to elevated internal resistance — either from aged cells or poor contact at the battery rail. Check the terminal contacts on both the pack and the drill for corrosion or debris first. If contacts are clean, measure open-circuit voltage: a healthy 12V Ni-MH pack should sit between 13.2V and 14.4V fully charged. A reading below 12.0V under no load means the cells are no longer holding capacity and the pack needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416059379802,"sku":"BWCS-FCD120PW-1","price":85.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416059412570,"sku":"BWCS-FCD120PW-2","price":100.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416059445338,"sku":"BWCS-FCD120PW-3","price":111.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FCD120PW-1.webp?v=1779759808","url":"https:\/\/batteryweb.com\/products\/festool-ccd12-replacement-battery-12v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
