It fits the BDCDMT120 compact drill\/driver and over 94 additional 20V MAX platform models including the CHH2220, LCS120, and LDX120C. Slides into any 20V MAX port that accepts the LB20, LBX20, LBXR20, or LBXR20B pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e20V MAX platform fit:\u003c\/strong\u003e\n    Black \u0026amp; Decker's 20V MAX line shares a common battery interface across drills, saws, and oscillating tools. The voltage rail, slide-in connector geometry, and BMS communication protocol are consistent across models — so one pack works across the full range without adapters or 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 BDCDMT120 under repeated load cycles. The BMS handled motor-start inrush current without tripping, held the voltage rail steady through mid-cycle torque spikes, and triggered thermal protection only under sustained overload — not normal use.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst two cycles on a new pack:\u003c\/strong\u003e\n    Run the drill at half load for the first two charge cycles before pushing maximum torque applications. This gives the BMS time to profile the motor's inrush current draw and set accurate overcurrent thresholds before you hit it 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 BDCDMT120 motor-start inrush surge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eEvery trigger pull on the BDCDMT120 sends a brief inrush spike before the motor reaches operating speed. On a cold or freshly installed pack, the BMS overcurrent threshold may not yet match the motor's start-up profile. If the pack cuts out immediately on trigger pull — not under load, but at the first instant — that is an inrush trip, not a faulty cell. Two to three partial charge-discharge cycles recalibrates the BMS threshold and eliminates nuisance trips in most cases.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red on a new 20V pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If a pack sits long enough, cell voltage can drop below the charger's acceptance threshold — typically around 2.5V per cell. The Black \u0026amp; Decker charger sees sub-threshold voltage and blinks red instead of starting a charge cycle. To recover, connect the pack to the charger and leave it for 30 minutes without interruption — most chargers apply a trickle pre-charge below 2.8V per cell before switching to the main charge cycle. If the light does not shift from red within 45 minutes, check that resting cell voltage is above 2.5V with a multimeter before continuing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416055971930,"sku":"BWCS-BPL120PW-1","price":42.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416056004698,"sku":"BWCS-BPL120PW-2","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416056037466,"sku":"BWCS-BPL120PW-3","price":53.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPL120PW-1.webp?v=1779759807","url":"https:\/\/batteryweb.com\/products\/black-decker-bdcdmt120-replacement-battery-20v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
