2 Packs 3.0Ah 20V MAX Lithium lon Battery Replacement for Porter Cable 20V Battery PCC680L PCC681L PCC685L PCC682L PCC685LP PCC680LP PCC600 PCC640 PCCK602L2 Cordless Drill Power Tools

I’m writing this review early but will update if issues arise. I was hesitant to buy off brand batteries for my tools because the saying is true “you get what you pay for”. I’ve had bad luck w off brand tools before but my budget wouldn’t allow for 2 new Porter Cable 20v batteries. I had a rather larger job here at home to do involving driving hundreds of #10 6” screws in landscape Timbers. I started out w my PC batteries that I got w my drills and they died fairly quickly. I put in one of these batteries freshly charged and not only did one battery finish the job but it was driving the screws stronger and faster than my PC batteries. Not only did it drive many screws but also I drilled ½” holes for rebar through 2 rows of landscape Timbers and still had plenty of life left after the job was done.I do hope these batteries last as long as my PC ones have done.So for now they’re worth the money to buy off brand

Comparing to the branded batteries, these do the job just as well. Can't tell the difference so far. Expect to last a long time if not used improperly or maintained as suggested. Satisfied with this battery purchase.

Seem to work as well as factory ones time will tell

I have several cordless tools that require this battery. When the batteries played out the replacements were too costly but these worked well. Will see how they hold up in the next few days

Battery life lasted longer than expected and to my surprise longer than original Battery. Also with the 3 amps it had a little more power to help my tools.So worth the price at half the price of OEM for two of them and they work great

batteries last a good while.

Drills

Bought a two pack. One battery stopped charging after just two charges, the second still works but it does not last nearly as long and the same sized OEM battery.
