### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Good Product - Worked For My Application
  

*by B***R on Reviewed in the United States on November 6, 2024*

I made the dumb move of replacing the battery on my brand-new solar powered radio because the factory battery just wouldn't hold a charge. Turns out the factory battery wasn't at fault; it's the radio itself that's defective. It apparently continuously discharges the battery, whether you're using it or not. So... this battery was the perfect replacement and works great. Since the radio is junk, I now have a spare battery. I don't know what to do with it, but I'm sure I'll think of something. :-)
