It slots into the same slide-rail receiver as the original LBXR12, BL1110, BL1310, BL1510, LB12, and LBX12 packs. Voltage and connector pinout match OEM spec — the BMS handshake clears on the standard Black \u0026amp; Decker charger.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBDCDMT112 and EGBL108 platform fit:\u003c\/strong\u003e\n    These models share a common 12V slide-rail connector and a three-pin BMS communication line. Any pack carrying the LBXR12 or BL1x10 OEM numbers uses the same physical latch geometry and the same charge-state signalling protocol — which is why a single replacement covers the full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the BDCDMT112's motor-start inrush sequence. The BMS cleared overcurrent on trigger pull without nuisance tripping, held the 12V rail steady through mid-torque driving cycles, and accepted a full charge cycle on the standard Black \u0026amp; Decker 12V charger without a fault code.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use break-in on the BDCDMT112:\u003c\/strong\u003e\n    On first use, run the drill at half load — soft wood, small-diameter bits — for two full discharge-charge cycles before pushing it to maximum torque applications. This lets the BMS profile the motor's inrush current signature before it finalises its overcurrent protection thresholds.\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 with the BDCDMT112\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BDCDMT112 draws a short, sharp current spike the instant the trigger closes — this is motor-start inrush, and it can be two to four times the steady running current. A fresh replacement pack with a conservatively calibrated BMS may trip its overcurrent threshold on that spike before the motor reaches speed. Running the tool at moderate load for the first two cycles teaches the BMS the actual inrush profile of this specific motor and raises the trip threshold accordingly. After that break-in, nuisance cutouts on trigger pull typically stop.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the new pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge slowly during warehouse storage. If a cell drops below approximately 2.5V per cell, the Black \u0026amp; Decker 12V charger's pre-charge detection circuit will refuse to begin a charge cycle — the indicator either blinks red or shows no response. The fix is a short boost charge: leave the pack seated in the charger for 10–15 minutes without removing it, even if no light appears initially. Most chargers will detect cell voltage recovery and transition to normal charge mode once the pack climbs back above the 3.0V-per-cell acceptance threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416050171994,"sku":"BWCS-BPX120PX-1","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416050204762,"sku":"BWCS-BPX120PX-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416050237530,"sku":"BWCS-BPX120PX-3","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPX120PX-1.webp?v=1779759807","url":"https:\/\/batteryweb.com\/products\/black-decker-bdcdmt112-replacement-battery-12v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
