It fits the PCC601 drill platform and a wide range of Porter Cable compact tools sharing the 18V slide-pack interface. OEM part numbers covered include PCC681L, PCC680L, PCC685L, PCC682L, and PCC685LP.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePCC601 platform compatibility:\u003c\/strong\u003e\n    These models share a common 18V slide-rail connector and use the same BMS handshake protocol. The cell pack, terminal layout, and communication line all match across the PCC68x family, so one battery covers drills, impact drivers, and compact circular saws in the same lineup.\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 through repeated motor-start cycles and sustained torque loads. The BMS held overcurrent protection thresholds correctly, cell balancing stayed within tolerance, and the charger recognised the pack without fault codes on every cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMotor break-in on first use:\u003c\/strong\u003e\n    On the first two uses, run the drill at half load before pushing full torque. This lets the BMS log the motor's inrush current signature and set overcurrent trip thresholds accurately — preventing nuisance cutoffs during later high-torque applications.\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 drill\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen you pull the trigger hard on a stalled or loaded drill, current spikes sharply before the motor reaches speed. A fresh or cold pack can trip the BMS overcurrent threshold at that spike, cutting the tool instantly. This is not a faulty battery — it is the BMS protecting the cells from a current surge the protection circuit reads as a short. If cutoffs happen repeatedly, check that rail contacts are clean and seated fully, as added contact resistance amplifies the voltage drop and worsens the spike.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharger flashing red and not accepting the pack after storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion packs stored for several months can drop below 2.5V per cell — the minimum voltage most chargers will accept for a charge cycle. The charger reads this as a damaged pack and flashes red instead of initiating charge. To recover the pack, place it in the charger and leave it for 10–15 minutes without removing it — many Porter Cable chargers include a trickle recovery mode that slowly raises cell voltage to the acceptance threshold before switching to full charge. If the charger still rejects the pack after 20 minutes, check individual cell voltage with a multimeter; any cell below 2.0V indicates an unrecoverable cell-level failure.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416041259098,"sku":"BWCS-PTC681PW-1","price":74.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416041291866,"sku":"BWCS-PTC681PW-2","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416041324634,"sku":"BWCS-PTC681PW-3","price":96.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PTC681PW-1.webp?v=1779759709","url":"https:\/\/batteryweb.com\/products\/porter-cable-pcc601-replacement-battery-18v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
