It matches the voltage rail and connector footprint of the OEM pack. Capacity is rated at 5000mAh (72Wh) — use the Wurth charger designed for 14.4V Li-ion packs.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBS 14-A Combi and BS 14-A Power fit:\u003c\/strong\u003e\n    Both models run the same 14.4V battery platform with identical connector pinout and BMS communication protocol. One replacement pack covers both tools without adapter or wiring changes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through repeated motor-start inrush events on a drill load rig. The BMS held its overcurrent threshold through trigger-pull spikes and did not trip under normal drilling loads at rated torque.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in procedure for first use:\u003c\/strong\u003e\n    On first use, run the drill at half load for two full cycles before applying maximum torque. This lets the BMS log actual inrush current from your specific motor before locking overcurrent protection thresholds.\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 BS 14-A\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe BS 14-A's brushed motor draws a sharp current spike the instant the trigger pulls — often 3–5× the running current. A new pack's BMS starts with conservative overcurrent thresholds and may read that spike as a fault. The battery cuts out immediately on trigger pull rather than during sustained load. Two break-in cycles at reduced load allow the BMS to recalibrate those thresholds to the motor's actual inrush signature.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising this pack after it sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells discharge slowly in storage. If the pack voltage drops below roughly 10V, most Wurth 14.4V chargers refuse to begin a charge cycle — the charger shows no light or blinks an error. Remove the pack, wait 60 seconds, and reinsert it firmly to force the charger to re-poll the BMS. If the charger still does not respond, the pack needs a recovery pulse — a charger with a manual recovery or \"boost\" mode will push the cells back above the 10V acceptance threshold before switching to normal charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416033329242,"sku":"BWCS-DEC730PX-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416033362010,"sku":"BWCS-DEC730PX-2","price":129.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416033394778,"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\/wurth-bs-14-a-combi-replacement-battery-144v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
