    • Affordable replacement that works perfectly!
My Black+Decker leaf blower suddenly stopped working, and I wasn’t sure if the issue was the battery or the unit itself. I looked into getting a genuine battery from the brand, but it was surprisingly expensive. Then I found this more affordable alternative — and it works perfectly! No issues at all, and my blower is back in action like nothing ever happened. Great value for the price, and I’m glad I didn’t spend extra for the brand name. ... show more

    • Does the job well
Over the past year the battery has proven an excellent replacement battery for my Greenworks 40 V electric lawn mower; the charge is eminently suitable for mowing my small rear lawn and front strip lawn, taking about an hour to recharge.

    • Good value, works great
Definitely a value item compared to OEM battery. OEM battery lasted 10+ years, we'll see how long these last... They charge normally in the OEM charger and seem to have the same run time as the original battery for my string trimmer. Very happy at thei point.

    • Junk
Lighter and smaller than original. Died after owning for 6 months. Cheap knock off. Didn’t get much use. Spend a little more, buy from Black and Decker.
