It fits the P40GC and PD40CS40 models, along with other tools in the 40V-System lineup that share the same slide-in connector and voltage rail. Capacity is 2000mAh (80Wh) — match that against your original before ordering.\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, PD40CS40, and compatible 40V-System tools share a standardised 40V rail and connector interface. The BMS in each tool handshakes with the pack over the same communication line, so one battery format serves the full platform without adapter hardware.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through repeated motor-start inrush cycles on a 40V-System drill. The BMS held the overcurrent threshold without nuisance tripping and balanced cells correctly across charge and discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBreak-in procedure for 40V-System tools:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before applying maximum torque. This lets the BMS profile the motor inrush current draw and set overcurrent protection thresholds accurately before you push it 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 40V-System tools\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a brushless motor starts under load, it pulls a current spike — sometimes three to five times the running draw — in the first milliseconds of trigger pull. If the BMS has not profiled that motor's inrush signature, it can read the spike as a fault and cut output. On a fresh pack, this shows up as a single hard stutter on trigger pull, then normal operation once the BMS resets. Running two half-load cycles first allows the protection circuitry to calibrate its overcurrent window to the actual motor load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger not recognising the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the pack drops below roughly 2.5V per cell, most chargers will not begin a charge cycle — the acceptance voltage threshold is a safety gate, not a fault. The charger may blink red, show no response, or cycle between red and green without progressing. To recover, some chargers have a conditioning or recovery mode; select it, connect the pack, and allow a low-current trickle for 10–15 minutes until the cell voltage rises above the acceptance threshold and normal charging begins.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416010850394,"sku":"BWCS-GWP401PW-1","price":109.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416010883162,"sku":"BWCS-GWP401PW-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416010915930,"sku":"BWCS-GWP401PW-3","price":143.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GWP401PW-1.webp?v=1779759245","url":"https:\/\/batteryweb.com\/products\/powerworks-40v-system-replacement-battery-40v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
