It replaces OEM part numbers FS140BX, A18, FSB18, and several compatible references across the BD and FS platform. Capacity is 43.2Wh — matching the original pack specification from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBD and FS platform compatibility:\u003c\/strong\u003e\n    The BD14PSK, FS1400D, and FS1402D series share the same 14.4V rail voltage, connector footprint, and charge-termination logic. That common platform means one pack fits across the line without modification or adapters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on the BD14PSK platform. The BMS handled inrush current on trigger pull without tripping, and delta-V termination on charge completed cleanly at full capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eNi-MH break-in on first use:\u003c\/strong\u003e\n    Run the drill at half load — driving medium screws into softwood — for the first two cycles before pushing full-torque applications. This lets the cells reach stable operating temperature and allows the charger to refine its delta-V cutoff window before you demand maximum draw.\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 drill motor-start inrush surge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a stalled or heavily loaded drill, the motor draws a spike of current that can be three to five times the steady running draw. On Ni-MH packs, if the cells are cold or partially discharged, internal resistance rises and the voltage rail dips sharply at that moment. The BMS interprets this rail drop as an overcurrent fault and cuts output. The fix is to let the pack warm to room temperature before use and avoid stalling the bit under full-speed trigger input — ease in at low speed first, then increase.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising a pack that has been sitting in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage — a pack left unused for three or more months can drop below the charger's minimum acceptance voltage. The charger sees the low voltage, flags it as a bad or faulty pack, and refuses to begin the charge cycle. To recover the pack, place it in the charger and watch for a trickle-charge initiation: most Firestorm chargers apply a low-rate conditioning current first. If the indicator stays on fault, measure cell voltage across the pack terminals — anything above 10V total on a 14.4V pack is recoverable; below that, the cells may not accept charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416044994650,"sku":"BWCS-BPS142PX-1","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416045027418,"sku":"BWCS-BPS142PX-2","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416045060186,"sku":"BWCS-BPS142PX-3","price":120.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BPS142PX-1.webp?v=1779760117","url":"https:\/\/batteryweb.com\/products\/firestorm-bd14psk-replacement-battery-144v-3000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
