It fits the HP14KD, CD14CA, CD14CAB, CD14CB, and over 160 additional 14.4V Black \u0026amp; Decker tools that share the same slide-in battery platform. Replaces OEM part numbers including A9262, A9276, PS140, HPB14, BD1444L, and A14, among others.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHP14KD and CD14CA platform compatibility:\u003c\/strong\u003e\n    These models share a common 14.4V slide-in connector and BMS handshake protocol. The battery's cell configuration and terminal layout match the OEM spec, so the charger recognition circuit reads the pack correctly without manual intervention.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on an HP14KD under repeated trigger-pull cycles and sustained fastening loads. The BMS held overcurrent protection thresholds stable across motor-start inrush spikes, and cell temperature stayed within the pack's thermal limits under continuous use.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush break-in:\u003c\/strong\u003e\n    On first use, run the drill at half load — light drilling or driving — for two full charge-discharge cycles before applying maximum torque. This lets the BMS profile the motor's inrush current draw and set accurate overcurrent thresholds before you push the pack 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 trigger-pull inrush surge in 14.4V drill-drivers\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a cordless drill, the motor draws a short burst of current — often three to five times the running current — before it reaches speed. A Ni-MH BMS set conservatively will interpret that spike as a fault and cut power. This pack's overcurrent threshold is calibrated to the HP14KD motor profile, so the BMS distinguishes a normal inrush event from a genuine short. If you do see a cutout on trigger pull, the cells are likely under-charged — bring the pack to full charge before the next use.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs under load and feels underpowered mid-task\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eVoltage sag under load is a separate failure from a hard cutout. The drill spins but loses torque, and the motor sounds strained. The most common cause is high resistance at the battery rail contacts — corrosion or debris on the slide-in terminals reduces the current the tool can actually pull. Clean the battery contacts and the tool's terminal rails with isopropyl alcohol, then recheck. If sag persists after cleaning, measure the battery voltage under load — a healthy 14.4V Ni-MH pack should hold above 12.5V during normal drilling.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416045846618,"sku":"BWCS-BPS140PW-1","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416045879386,"sku":"BWCS-BPS140PW-2","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416045912154,"sku":"BWCS-BPS140PW-3","price":120.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPS140PW-1.webp?v=1779759665","url":"https:\/\/batteryweb.com\/products\/black-decker-hp14kd-replacement-battery-144v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
