    I’ve been using my dewalt drills for about 2-3 months now with the stock 1.3Ah batteries. I found myself charging the batteries at least once a day while laying my subfloor. After recently purchasing the 3Ah, I installed a whole bedroom of subfloor in one day without having to charge the battery once, and it still has juice left! I would highly recommend this product for the homeowner doing basic renovations. Anything bigger is just overkill. Also, this has two batteries in one pack so I doubt I will ever have to stop and recharge during a project again.

    I purchased these during an in store Dewalt promotion. If you’re going to be doing any project, nothing is worse than having to wait because of a dead battery. With this 2 pack you will always have the spare ready to finish the job.

    [This review was collected as part of a promotion.] The 20v 3ah battery (DCB230), works great for my tools. It has a nice light weight and compact in size, which makes it great for my usual projects/ jobs. It has a fast charge time, also lasts quite a while for use. Some down sides are that it will not fit in my DeWALT Tough System Radio (DWST08810) and they do rub a little against the belt hook clips on my drills and impacts. But that isn’t a big problem with the belt hooks. The rubbing is very minimal. Overall, I like that it is compact, very light in weight and that it has the fuel gauge on it. Love Dewalt products! I will be picking up the 2 pack at my local hardware store.

    Purchased these batteries to use in my old 18v tools. Using a dealt converter. Batteries run full speed until they are out of power, unlike the old 18v that slowed down as they were running out of charge.

    I haven’t used them for very long, but these batteries offer much longer use before you have to recharge them (over the 1.5 amp hour ones that come with the tools). They were on sale (2 for just under $100), and I feel that is quite a deal. I really don’t know how they will perform a year from now, but my 1.5 amp hours still hold as much of a charge as they did when they were new, so I have high hopes.

    The batteries have more than enough run time for long projects. Having two batteries allows one to be charging while the other is in use. I have made the switch from old Rigid 18V set to this Dewalt 20v and couldn’t be happier.

    The 3 amp allows me to work twice as long and makes the workflow faster. Glad I chose to update to a larger life battery. Hasn’t let me down yet.

  8. Tradesman

    Bought it on sale. I got the two pack for about the price of a single. Good addition to my current 1.5 amp-hour batteries. Only adds a little more weight for double the run time. I spend less time waiting on batteries to charge now.

    I have an 18V DeWalt combo kit from 15 or so years ago the batteries kept dying out and needed to be replaced, bought a 20V adapter and they work better than they have in years.

  10. Joeman

    Just bought these two weeks ago, but off to a good start and nice upgrade from the 1.5amp that comes standard with some of the buy-one/get-one sets

    I love and use DeWalt tools almost exclusively. I looked into generic batteries as spares for my 20v tools but opted for the more expensive, but better, batteries. My only complaint is that when I looked at the date code on the batteries they were 2019. That is two years past the date I ordered them!! I would have figured that with the Covid-related shortages that I wouldn’t get old product. Not real happy since if I have an issue with the warranty I am pretty much out of luck. So, I guess buy in store (risk Covid) so you can see the date codes.

    The stock power packs do not last long enough in high demand applications.

  13. WW

    I’ve only charged and used one (along with two smaller batteries from my drill purchase last year) SO far. That keeps a charged one ready to go all the time. I’m drilling holes in red clay and rocks to plant daffodils, so the batteries and motor seem to be working just fine. The auger; I’ll get a new one next time at .

  14. Josh

    I purchased these batteries to help complete jobs without having to change them constantly. They are completely what I wanted and only charge them once or twice a week depending on job requirements. The battery life button is also handy.

  15. Wheels

    This battery pack is awesome. Much more powerful and longer lasting than the batteries that came with the tools. Also purchased a twin charger pack which allows me to charge two batteries at a time. Great time saver.

    ordered from and received 2019 batteries DeWalt only warranties for 3 years come on you can do better than that I returned to store and got ones manufacturer in 2021the one star rating is for .com

  17. Sandekt63

    These higher amp batteries woke my tools up. So much more power than what I was using. And alot more run time before recharge needed. No dislikes about this product

  18. Dahoot

    The extended life of the battery is ideal for use with the circular saw. I highly recommend purchasing the 3ah or higher batteries. The 2 pack is an amazing deal.

  19. Hal

    Great large capacity with built in charge indicator
