Porter Cable PCC680L 20V Replacement Battery 2000mAh

Porter Cable PCC600 Series — 20V Li-ion Replacement Battery (PCC680L)

This is a 20V Li-ion battery rated at 2000mAh (40Wh), built to fit the Porter Cable 20V MAX cordless platform. It slots into drills, impact drivers, circular saws, and other 20V MAX tools across the PCC600 series. Verified compatible with PCC600, PCC601, PCC601LA, PCC620B, and 38 additional models on the same 20V rail.

• 20V MAX platform fit: Every model in the PCC600 series shares the same 20V battery rail, five-pin connector pinout, and BMS handshake protocol — so one pack covers drills, saws, and impact drivers without adapter rings or firmware changes.
• Bench tested on actual hardware: We ran this pack through charge-discharge cycles on a PCC601 drill and a PCC620B circular saw. The BMS held the cutoff threshold correctly on both motor-start inrush events and sustained load draws without tripping prematurely.
• First-use load conditioning: On first use, run the tool at half load for two cycles before applying full torque or maximum blade speed. This allows the BMS to profile the motor's inrush current draw and set overcurrent protection thresholds before it sees peak demand.

BMS cutoff on circular saw motor-start inrush surge

When you pull the trigger on a circular saw, the motor draws three to five times its running current in the first 50–100 milliseconds. On a new or recently stored pack, the BMS may read that spike as an overcurrent fault and cut power before the blade reaches speed. This is a BMS threshold calibration issue, not a dead cell. Run two half-load cycles first — a drill at low torque works well — so the BMS logs normal inrush data before the saw's higher spike arrives. After that conditioning, the cutoff threshold adjusts and the saw starts cleanly.

Charger blinking red on a new 20V pack after storage

Porter Cable 20V chargers reject packs sitting below roughly 2.5V per cell — a common state after warehouse storage. The charger blinks red and stops rather than attempting a full charge cycle. To recover the pack, place it in the charger and let it attempt the wake-up pulse for 30 seconds, then remove and reinsert it. If the cell voltage has recovered above the acceptance threshold, the charger will switch to its normal green-blinking charge cycle. If red blinking persists after three attempts, measure pack voltage at the terminals — a reading below 14V on this 20V pack indicates cells need a trickle recovery charge before the standard charger will accept it.
