Best price I could find
Style: Battery
Seem to be true Dewalt batteries. They work well, and way better price than I could find locally.

Long lasting
Style: 20V battery
Long lasting per charge. First battery failed at 5 months. Customer service was excellent. Had new battery in less than two weeks.

Compact and light best for Drills/Drivers
Style: Battery
I have just about every DeWalt 20v tool, from basic drill to pole saws, hedge trimmers, etc. Very happy with all. I have a collection of 5AH and 6AH batteries, and ordered a pair of 2AH to use with my drill and 1/4" impact driver, due to light weight and compact size. I don't have experience with the "power stack" batteries or the 20/60 flex batteries. Received the 2AH today. 2/3 charge. Worked fine with my drill, and they are on the charger now. With regard to power/weight, the 2AH weight 365 grams (182g/AH), the 5AH weigh 635 grams (127 g/AH), and the 6ah (which is huge relative to the 5) weighs 975 g (162 grams/AH), so from that standpoint the 5AH is a clear winner in terms of power to weight. With regard to cost/AH, the 2AH pair cost $71 ($35.50 each, $17.75 per AH), the 6AH is currently selling on Amazon for $202.49 for a pair ($ 101.25 each, $20.25 per AH, and the 5AH is currently selling on Amazon for $129 for a pair ($64.50 each, $12.90 per AH). There is even a kit of 2 5AH, charger, and bag for $131.19 which is a great deal if you don't already have a charger(s). I knew this going in, and bought the 2 AH for compact size and less weight, but for power to weight and cost per AH, the 5AH seems to be the "sweet spot". You can do the math for other batteries (but I don't have weights): The "power stacks) are quite pricey. The 9AH 20/60 flex volt is $17,17 per AH, etc. In summary, the 2AH are light and compact, but not the best "value". Do your own comparisons based on your tools and needs. I don't know that I would trust the "knockoffs", fearing that I might set my house on fire.... ... show more

original dewalt battery.
Style: 20V battery
This is a legit dewalt battery, not a fake ,at least the one I purchased was. I called dewalt to register this battery. they wanted pictures of battery to verify a fake. It was not. But bear in mind that Mega Tools is not a authorized dewalt retailor. And dewalt will not honor the 3 year warranty.

Never underestimate the power of a little!
Style: Battery
If you are elderly with arthritic hands, it sure helps to have a powerful battery for your DeWalt tools that isn't heavy. These 2AH batteries provide enough power to get me through several hours of work. Then, while I rest a bit, they charge up quickly and are ready to work again. If only my energy would return so quickly! ... show more

Excellent quality
Style: Battery
Quick, easy tranaction. They appear to be genuine, complete with the “ fuel gauge” some models lack. Very satisfied at this initial point.

DEWALT battery
Style: 20V battery
I previously wrote a bad review on a Dewalt 20V Max battery. Come to find out the battery was perfectly fine, and it was my charger that was no good. I bought a new charger and not only did this battery charge right up, but my old one did too. I eft a bad review prematurely. I now rate this transaction 5 STARS! "My battery doesn't hold a charge. I've been trying to get a project done and can only drive 6 screws in before it's dead. Worst money I ever spent, and I've been around a LONG time." ... show more
