It fits the DeWalt XR Li-Ion 18V platform, covering cordless drills, impact drivers, circular saws, and compatible compact tools across the DCD and DCB series. Voltage and connector match the OEM pack — the charger and tool BMS read it identically.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eXR 18V platform compatibility:\u003c\/strong\u003e\n    DeWalt's XR 18V line shares a common voltage rail and slide-mount connector across drills, saws, and drivers. The BMS handshake uses the same cell communication protocol across DCB180 through DCB206 variants, which is why one replacement covers that full range of tools and chargers.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through a DCD780 drill and a DCB112 charger. The BMS accepted the charge cycle without error, cell balancing completed normally, and no overcurrent flags were triggered during motor-start inrush on a 25mm auger bit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor-start break-in on XR tools:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before full-torque applications. This lets the BMS log the motor's inrush current signature and set accurate overcurrent thresholds — reducing nuisance cutoffs during heavy trigger pulls later.\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 surge in XR drills and saws\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger hard on a drill or circular saw, current spikes sharply for the first 80–120 milliseconds as the motor overcomes static load. A freshly installed or storage-depleted pack has higher internal resistance, which amplifies that voltage dip at the cell level. If the dip crosses the BMS undervoltage threshold — typically around 14–15V on an 18V pack under surge — the BMS trips and the tool cuts out instantly. Two break-in cycles at partial load lower internal resistance enough that subsequent full-torque trigger pulls stay above the cutoff threshold.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red on a new or stored DCB180 pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDeWalt chargers like the DCB112 and DCB115 require cell voltage to be above approximately 12V before they enter normal charge mode. A pack stored for several months can self-discharge below that acceptance threshold, causing the charger LED to blink red and halt. Place the pack in the charger and leave it for 10–20 minutes — most DeWalt chargers run a trickle pre-charge at around 100mA to recover cells sitting between 10V and 12V. Once the pack climbs above 12V, the charger switches to standard CC\/CV mode and the LED turns solid red, then green.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416028741722,"sku":"BWCS-DEC181PW-1","price":68.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416028774490,"sku":"BWCS-DEC181PW-2","price":80.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416028807258,"sku":"BWCS-DEC181PW-3","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEC181PW-1.webp?v=1779759461","url":"https:\/\/batteryweb.com\/products\/dewalt-xr-li-ion-18v-replacement-battery-18v-1500mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
