    Reviewed in Canada on April 26, 2025
    Verified Purchase
    Although my 2.0Ah & 5.0Ah Dewalt batteries dating back as far as 2017 are doing just fine, we wanted give these POWERSTACK's a try. Yes, these are only 1.7Ah but I like the size when paired with certain tools, and according to the reviews they should pull their weigh and some. So far I have no complaints and would likely purchase again at "my" sale price.

    DeWalt is my first choice for power tools. I have been using DeWalt for 20 years. Unfortunately their battery housing is not very strong for mechanical work. They chip and break easily. But the battery itself has a very good lifespan. I still use my 18 year old batteries and hold them together with electrical tape. However, these two batteries drain very quickly.

    Its great product, I use it daily. My only suggestion is that they will remove the rubber part of it and replace it with plastic. For the reason that, the rubber will slowly peel off overtime...

    Reviewed in Canada on June 7, 2025

    If you can avoid it, then don't buy these batteries, without doubt the worst batteries I've ever bought. I'm a professional contractor and almost all my stuff is dewalt and I was so disappointed when I used these, they don't last long but biggest problem is if you leave this battery sitting for a short time and it dies then it will not recharge. I've had just about every battery dewalt make but these consistently do the same thing. I've binned about 8 of these and I wouldn't take one if it was free!!! Absolute garbage.
