It fits the DeWalt DC733K2 compact drill\/driver kit along with the DC731KA, DC735KA, DCD930B2, and over 80 additional 14.4V DeWalt platforms. The connector and BMS handshake match the original DeWalt 14.4V slide-pack interface.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e14.4V slide-pack platform compatibility:\u003c\/strong\u003e\n    The DC733K2, DC731KA, DC735KA, and DCD930B2 all share the same 14.4V slide-rail connector and BMS communication protocol. One battery services the entire platform without adapters or firmware changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a DC733K2 under repeated motor-start cycles. The BMS handled inrush current without tripping, held the 14.4V rail steady through fastening sequences, and reported state-of-charge correctly to the tool's indicator.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in on your drill\/driver:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before maximum-torque applications. This lets the BMS profile the motor's inrush current draw and calibrate its overcurrent protection threshold before you hit the drill 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 motor-start inrush surge in the DC733K2\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DC733K2 motor draws a sharp current spike the instant the trigger is pulled — this inrush can be three to five times the steady-state draw. A new pack from storage has a partially discharged cell stack, which raises internal resistance and amplifies the voltage dip at that spike. If the BMS reads the dip as an overcurrent event, it trips and cuts power before the motor reaches speed. Running two partial-load cycles first lets the BMS set its inrush threshold accurately against a warm, profiled cell stack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger shows blinking red on a new DE9141 pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDeWalt 14.4V chargers check cell voltage before starting a charge cycle — if any cell reads below approximately 2.5V per cell, the charger rejects the pack and blinks red. A battery that has sat in storage for several months can drift below that threshold through self-discharge. To recover it, place the pack in the charger and hold it there for 10–15 minutes without removing it — most DeWalt chargers include a trickle-recovery mode that brings low cells up to the acceptance voltage before switching to full charge. If the light stays red past 20 minutes, check that the slide-rail contacts are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416033230938,"sku":"BWCS-DEC730PX-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416033263706,"sku":"BWCS-DEC730PX-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416033296474,"sku":"BWCS-DEC730PX-3","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DEC730PX-1.webp?v=1779759609","url":"https:\/\/batteryweb.com\/products\/dewalt-dc733k2-replacement-battery-144v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
