Customer Reviews
⭐⭐⭐⭐⭐ Excellent Dewalt replacement
by Steve M.
Works perfectly with my Dewalt DCB206 tools. The 9Ah version is heavy but lasts all day on the job site. I've been using it for 2 months with zero issues. Charging on OEM charger works fine.
⭐⭐⭐⭐⭐ Better than I expected
by Dave L.
Was hesitant about aftermarket batteries but these are genuinely good. The 5Ah is lightweight for everyday use, the 6Ah is my go-to for heavier work. All fit my Dewalt tools perfectly.
⭐⭐⭐⭐ Great value pack options
by Tommy G.
Got a few of these for my crew. They hold up well on construction sites. The battery indicator is handy. One small issue: the 9Ah doesn't fit in some of our older Dewalt tools due to size.
