Like everyone I hate buying batteries but the price alone not to mention the quality you get when buying a DEWALT product. I tried the after market batteries and found they spend more time on the chargers then on the tool. I can, without reservations, say that I am very happy with this purchase, and would 100% recommend it to others.

One of the best deals I ever got on Amazon deal of the day. Be sure to by the converter for your 18volt tools so you can use these on them also. Old batteries really started losing longevity in my 18 volt set. It works great!!!

got these at a good price, not enough time to determine the reliability or longevity. Charged all four upon arrival and the batteries charged quickly and seems to get a full charge. Used a 4 amp hour and a 2 amp hour until drained and the battery lasted as long as expected.

These batteries are crazy expensive wherever you go and this was definitely a sweet deal after shopping around. They’re not flex volt batteries but I’m a full service automotive mechanic and they get my jobs done with plenty of energy to spare. Those flex volt batteries are even more expensive than the regular XR and the regular XR are already so expensive!!! And I won’t waste my time and money on cheap knock off batteries. Good deal yall!

For work I bought a dewalt half inch drive impact that only came with one battery. For what I needed it for, one battery just wasn't enough. After researching all the deals this one is the most bang for my buck. The batteries fit snuggly on all my dewalt 20 volt max stuff. The battery life and charge times of the additional batteries is comparable to the original. I really didn't need the two 2 Amp hr batteries that came with it, I have added them to my dewalt collection I have at home. All in all I can't complain.

I like this battery package. For Drills and Impact drivers the smaller batteries get me through a day with no problem. But, for my other tools the bigger batteries are just what I need. I use the bigger batteries on my oscillating tool or nailer and don't have to swap out the smaller batteries multiple times.

The 4Ah packs are great for heavy use tools and while I wouldn't have bought the 2Ah packs alone, the bundled group is a good value. I have a DeWalt cordless hand held vacuum that makes good of the use smaller 2Ah batteries since they are light and we only use the handheld vac for quick pickup jobs. The 2Ah packs might also be just enough juice to finish a job with a larger tool after draining your larger batteries.

I got these on a special, for a lot less then the bundle separately. I almost felt guilty about the price, almost. I had either a pack of really small or really big DeWalt batteries. And not enough. It amazes me how long even these last, when fully charged, for smaller devices. Drills of all sorts, compressor, lights, sawsall... all of those can easily be powered by the four and even two ah batteries, for house jobs, for a very long time. The chain saw and circular saw really like the bigger batteries. Might require them? Anyway. Even without a deal, I would have been glad to have a few more batteries to fill out my kit. And these were the perfect set. I'd like a few 12ah, 60 flexes. But that will be for dreams or another day.

At 159 dollars I had to buy 2 ! The most affordable I’ve seen in a long time . Bought a 4 port battery charger also, charged all batteries just after unwrapping them , all took the charge and used one in my impact drill with zero issues. Under one hundred sixty it’s like getting the 2- two amp batteries for free !!
