4.0Ah 20V lithium-ion replacement

This 4.0Ah 20V lithium-ion battery replaces the original Porter Cable PCC685L pack. It fits a wide range of 20V Max cordless tools including drills, drivers, oscillating tools, blowers and nail guns. The pack is CE certified and tested by the manufacturer to match OEM performance. It suits users who need a fresh power source for existing Porter Cable equipment.

Lithium-ion chemistry and 20V platform limits

Lithium-ion chemistry delivers consistent voltage until the cell is nearly empty, but capacity drops in very cold conditions and the pack will not charge below freezing. The 20V Max platform caps peak voltage at 20 volts nominal, so runtime scales with the 4.0Ah rating rather than a higher voltage tier. Users who need longer runtime per charge must carry a second pack because the chemistry and voltage ceiling are fixed.

Slide-on pack with integrated latch

The battery uses the standard Porter Cable slide-on form factor with an integrated latch that locks onto the tool rail. No screws or adapters are required, so swapping packs on a job site takes seconds. The rugged housing protects the cells from dust and impact during daily use. The pack ships as a single unit without a charger or carry case.

Questions about this item

Should I pick the 4.0Ah version or a smaller capacity for my Porter Cable 20V tools?

The 4.0Ah pack stores 4000mAh, giving longer run-time per charge than lower-capacity packs on the same 20V platform.

What does the 20V 4.0Ah rating mean when I put the battery in my drill or driver?

It delivers 20 volts nominal and 4.0 amp-hours of capacity, so high-draw tools such as drill drivers or oscillating tools run longer before needing a recharge.

Does this battery use the standard Porter Cable 20V Max interface?

Yes, it fits the Porter Cable 20V Max slide-on system used by models including PCC685L, PCC680L, PCC681L and the wider tool list shown.
