Review: Just for this, so far it seems to be pretty good! - My factory battery was not keeping a charge, it this is after 6 years of heavy use. I attempted to get a replacement battery from a big box hardware store but they didn’t have the 40v battery in stock. I checked desertcart and there it was for a fraction of the price. It fit perfectly into my cordless blower and trimmer and works just fine!

### ⭐⭐⭐⭐⭐ Great product

Excellent product Long lasting Charges quickly

### ⭐⭐⭐⭐ Works great over all
*by R***� on September 18, 2025*

Overall works great, powers my black and decker mower and weedeater and blower fine. But it does flash red on the charger sometimes. It’s not one I can fully charge at one time. I have to leave it off charger for awhile then try and top it off if it won’t start flashing red. I keep a fan directly blowing on my batteries while charging bc I’m always worried about overheating them. My name brand ones don’t do that. Overall happy since this is way less expensive.
