PORTER-CABLE 20V MAX* Lithium Battery, 4.0-Ah, 2-Pack (PCC685LP)

Last a long time. Holds charge

I was initially put off by the price when I decided to get a more powerful battery for my Porter Cable 20V drill. So instead, I bought a much cheaper battery that was "compatible" with Porter Cable. Wrong. I had to modify the guides on the battery to make it work. Then it crapped out after about 20 cycles. And I did not realize how short the battery life was until I bought actual Porter Cable batteries. WOW! What a difference. So in spite of the slightly higher price tag, they are actually cheaper when you consider what you get. You get batteries that fit...nicely. You get batteries that last a long time. I can get 4 hours of hard use out of a battery in my reciprocating saw. All day and then some in a 3/8 drill, drilling 3/4 inch holes through framing lumber. I don't know how long they last in my circular saw...long time. So don't waste your money on "compatible', buy these instead

Compared to the replacement batteries for my dewalt drills these are a huge value. Paid a little over a bill for a pair of them and couldn't be happier with the performance of both. Ive used them during a bathroom remodel in almost all of my porter cable cordless tools with zero issues. They last longer than i do while using the circular saw to cut several pieces of paneling. The sawzall to rip a couple 2x4s up for a new medicine cabinet hole and exhaust fan mount. Used the impact driver sinking 2 inch drywall screws and the multi-tool the most and never had to change batteries all day. Thats by far the most impressive considering i had to replace the multi-tool blade halfway through the day.I hate to think that porter cable may be going the way of the dodo because they have offered excellent value and performance in both the 18v and 20v cordless tools ive got.

Much better than the cheap knock off brand I had bought before. I mean there is something to say about paying Twice as much but getting a run time that is almost four times as long from the real brand battery. The little 1.5 amp hour ones that came with the tools ran longer than the 6 amp hour knock off brand. These stay cooler when charging and they are certainly more sturdy. I have used these in a small circular saw, saber saw, reciprocating saw, oscillating tool, 2 drills and a impact driver, all of them performed perfectly with no overheating of the battery even on a day where it was over 115F here in Arizona.

So far so good because they are OEM batteries directly from Porter Cable.

Perfect addution

Original Equipment, not an off brand. Long battery life. Will pick up two more when they go on sale again.

As a contractor, there is a nice benefit to having cordless tools so long as they are ready to use at a moments notice. The original batteries that came with my Porter Cable tools are perfect for home-owner projects, or even craft making, but for long-range jobs you need a larger amp hour rated battery. The bigger batteries like this 4.0 amp hour are very helpful, and have performed very well.The other day I used my cordless circular saw to cut strips. I was able to cut 5 5" x 8' long strips from 1/2" plywood. Then, I used the same battery to drive an impact driver. I pre-drilled over 30 5/32" holes in concrete, and then used the same impact driver to screw the 1 1/4" screws in. All this was using the same battery. There is still power left in it, but the point is that I accomplished the task without recharging.There are many other lesser priced batteries available, but money-savings is not everything when you are on the job site. Spend the extra and buy a genuine product that Porter Cable provides.
