2 Pack 3.0Ah 20V Lithium-ion Replacement Batteries Compatible with Porter Cable 20V Battery PCC681L PCC682L PCC660 PCC641 PCC683L PCC685L PCC601 PCC670

The battery is just as good as the originals if not better than. They last as long and have the same power only at a fraction of the cost. This is the second pair I have purchased not because of a defect but because i use them constantly and is nice to have all my battery tools available at the same time. ill be buying two more soon to have backup in the chargers ready to go.

Not being able to find batteries for my porter cable has been the real issue. The drill works fine, it's just the lithium batteries give out after a couple of years. As long as there's a steady supply of these bad boys, I feel like this thing should get me through the next 10 years. I'm trying to avoid buying a new drill, when this one works fine.

I like the fact that it fits and works perfect.

seem to be great batteries so far!

for the price great product

Only one of the baterries would charge. The other one would not, so I am now going to have to go through the trouble of returning them. I am not sure if I will reorder the same ones or not.

the battery doesn't fit the tire inflater,I need to exchange it for the correct battery, how do I exchange it.

Charged one battery, used it on a drill with a paddle bit for one hole. It quit working, still shows fully charged on the charger. Older battery works fine.

these batteries are not good, don't last, junk, do not buy

It didn't work and I still haven't received a refund and I returned it to the Walmart 10-31!
