It fits the PCC601 and the broader Porter Cable 20V platform, covering drills, impact drivers, circular saws, and reciprocating saws. Drop it into any compatible 20V tool and it seats the same way the original does.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e20V platform fit — PCC601 and related models:\u003c\/strong\u003e\n    Porter Cable's 20V MAX tools share a common battery rail voltage, connector footprint, and BMS handshake protocol across the PCC6xx line. This pack communicates with the tool's onboard BMS the same way PCC681L, PCC680L, PCC682L, PCC685L, and PCC685LP packs do — voltage negotiation happens at the rail before the tool draws current.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack on a PCC601 drill and a circular saw. The BMS held steady through repeated motor-start inrush spikes and did not trip under sustained load at rated draw. Cell temperatures stayed within the protection window across multiple discharge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor inrush conditioning on first use:\u003c\/strong\u003e\n    On first use, run the tool at half load for two cycles before hitting full torque. This lets the BMS profile the motor's inrush current and calibrate its overcurrent threshold before you put the pack under maximum demand.\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 with the PCC601 and saw models\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger on a Porter Cable drill or circular saw, the motor draws a short burst of current — often 3–5× the running draw — before the rotor spins up. A new pack coming out of storage has a conservative BMS overcurrent threshold until it logs a few real-world cycles. If the threshold is set too tight, that inrush spike trips the protection circuit and the tool cuts out immediately on trigger pull. Running two moderate-load cycles resets the BMS learned threshold and brings it in line with the actual motor signature of your specific tool.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger blinking red on a new 20V pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePorter Cable's standard charger rejects packs where individual cell voltage has dropped below roughly 2.5V per cell — a common condition after extended shelf storage. The charger blinks red instead of beginning a charge cycle because it sees the pack as potentially damaged. Most chargers have a recovery mode: hold the pack on the charger for 10–15 minutes without interrupting contact, and the charger will attempt a slow trickle-wake sequence. If cell voltage recovers above 2.5V per cell, the charger switches to a normal charge cycle and the indicator goes solid or green.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416012324954,"sku":"BWCS-PTC681PH-1","price":104.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416012357722,"sku":"BWCS-PTC681PH-2","price":122.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416012390490,"sku":"BWCS-PTC681PH-3","price":136.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PTC681PH-1.webp?v=1779759486","url":"https:\/\/batteryweb.com\/products\/porter-cable-pcc601-replacement-battery-20v-5000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
