Porter Cable PCC680L 20V Replacement Battery 1500mAh

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

This is a 20V Li-ion battery rated at 1500mAh (30Wh), built to fit the Porter Cable 20V MAX cordless tool platform. It slots into drills, impact drivers, circular saws, and other handheld tools across the PCC600 series. Drop it in — the connector and BMS handshake match the original pack spec.

• PCC600 platform fit: The PCC600, PCC601, PCC601LA, PCC620B, and 38+ additional models share the same 20V rail, slide-in connector block, and BMS communication protocol — one battery body covers the full line without adapter plates or firmware changes.
• Bench tested on actual hardware: We ran this pack on a PCC601 drill and a PCC620B circular saw. The BMS handled motor-start inrush on both tools without tripping overcurrent protection, and the charger handshake completed normally on the Porter Cable stock charger.
• Break-in on first use: Run your tool at half load — light drilling or low-torque driving — for two full charge cycles before hitting maximum torque or sustained saw cuts. This lets the BMS sample the motor's inrush current profile and calibrate its overcurrent thresholds before you push the pack hard.

BMS cutoff on motor-start inrush with the PCC620B circular saw

A circular saw draws three to five times its running current in the first 50–100 milliseconds of blade spin-up. If the BMS has not yet profiled the motor, it can read that spike as an overcurrent fault and cut the pack before the blade reaches full speed. This is not a defective battery — it is the BMS protecting cells from an unrecognised load signature. Two break-in cycles at partial load allow the BMS to set a realistic threshold and stop tripping on normal start-up.

Charger blinking red on a new or stored 20V pack

Li-ion packs in storage self-discharge over time. If any cell drops below roughly 2.5V, most Porter Cable chargers enter a protection loop and flash red rather than begin a full charge. The fix is a slow pre-charge: if your charger supports a recovery mode, hold the pack in it for 10–15 minutes so the charger can raise the cell floor above the acceptance threshold. If it does not, a compatible charger with a recovery function will bring cells back up to the 3.0V floor needed to trigger a standard charge cycle.
