It fits the P40GC and PD40CS40 models, along with other tools in the 40V-System lineup including drills, impact drivers, circular saws, and lawn equipment. Voltage and connector match the OEM pack — no adapter needed.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e40V-System platform fit:\u003c\/strong\u003e\n    The P40GC and PD40CS40 share the same 40V battery rail and connector format across the Powerworks cordless lineup. One pack moves between tools without reconfigurations or adapters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a Powerworks 40V drill and circular saw. The BMS handled motor-start inrush current without tripping on standard trigger pulls, and cell voltage held stable through repeated load cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use load conditioning on high-torque tools:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before maximum torque applications. This lets the BMS log the motor inrush current draw before it sets overcurrent protection thresholds — reducing the chance of nuisance cutoffs on hard starts.\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 40V drills and saws\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eEvery brushless motor in the 40V-System lineup pulls a short, sharp current spike the instant the trigger closes. On a circular saw under load, that spike can exceed the BMS overcurrent threshold if the pack is cold or the cells are partially depleted. The BMS reads this as a fault and disconnects the output rail to protect the cells. Warming the pack to room temperature before use and avoiding full-throttle starts into dense material reduces the frequency of these trips.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTool bogs under sustained load but recovers when trigger releases\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the tool slows noticeably during a long cut or extended drilling but returns to full speed after a brief pause, the cause is voltage sag — not a depleted pack. Under sustained draw, internal cell resistance causes the pack voltage to drop below the tool's cutoff point, triggering a soft power reduction. Dirty or corroded rail contacts make this worse by adding resistance before the current even reaches the cells. Clean the battery contacts with isopropyl alcohol and check that the pack seats firmly — a loose fit increases contact resistance at the rail.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416036409434,"sku":"BWCS-GWP400PW-1","price":141.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416036442202,"sku":"BWCS-GWP400PW-2","price":166.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416036474970,"sku":"BWCS-GWP400PW-3","price":186.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP400PW-1.webp?v=1779759609","url":"https:\/\/batteryweb.com\/products\/powerworks-40v-system-replacement-battery-40v-3000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
