                  Have no issues. The batteries have been working good so far, only time of use will tell. It’s a perfect fit for my drill and impact, not to small, not to big. It’s in the sweet spot for the tool, power and battery life.
                  by
                  Great buy. The batteries seem to outlast the red brand. Would recommend buying.

                  DeWalt's 3.5 Ah PowerStack batteries are the perfect combination of size, weight, and long lasting power for hand tools such as my hammer drill and impact driver. I'm very happy with them.

                  Perfect sized for drill and impact. Noticeable performance increase compared to the regular battery comes with the combo with smaller foot print.
                  by
                  The DEWALT FLEXVOLT 9.0Ah Battery and Charger Kit delivers excellent power and runtime for demanding jobs. The battery lasts significantly longer than standard packs, and the charger works quickly and reliably. A great investment for anyone using DEWALT 20V or 60V tools.

                  Old batteries being sold
                  I purchased this battery a couple of months ago and just seen the date on the unit. If it is the DOM then it makes it four years old already, I have another battery that is newer and it seems to have a longer run time. If I purchase another one, then I will look at the date before I open and use it.

                    Great price on a Dewalt 3AH battery. You can never have enough of these, especially if you have multiple Dewalt tools.

                    Half price but 2022 manufacture. 1 bar charge when received. Hope they charge and hold up.

                      I love this 3.0Ah battery. It has plenty of power and works well, but best of all, it's lighter than the 5Ah and much easier on my hands.
