## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Did not last
  

*by H***N on Reviewed in the United States 🇺🇸 on December 15, 2021*

The battery price was good, as was the time it powered the tool I used it with ( a string trimmer) but it failed after 2-1/2 seasons of occasional use.

### ⭐⭐⭐⭐ 







  
  
    Battery for snowblower
  

*by S***N on Reviewed in the United States 🇺🇸 on January 1, 2020*

Great battery! The bad part is it would have been WONDERFUL if you had the charger that fits this battery on the same page. We ordered the wrong one first and had to return it. The second one was the correct fit. All good.

### ⭐⭐⭐⭐ 







  
  
    Company treated me well.
  

*by B***Y on Reviewed in the United States 🇺🇸 on July 2, 2020*

The battery worked fantastic.  Nice long battery life.  Stopped working a month later during a project with heavy load, but the company refunded me which was nice.
