## Customer Reviews

### ⭐⭐⭐⭐⭐ Worked great in my outdoor speaker
*by E***. on July 23, 2025*

I bought this to replace a failing outdoor speaker power source. The battery had the same plug installed as my outdoor speaker and it had a larger capacity as well. Worked great.

### ⭐⭐⭐⭐⭐ Replaced batteries in outdoor lights
*by A***R on May 17, 2025*

These were the perfect replacement and have lasted longer than the original batteries. Would recommend for replacement of any outdoor lights.

### ⭐⭐⭐⭐ Didn't start out good, but with a little tinkering, it seems to be working.
*by W***L on October 17, 2024*

It wasn't fully charged when I received it and it initially wouldn't take a charge. I let it run down to fully discharged, then it finally charged up, but didn't hold the charge. I charged it again and now it seems to be working okay. Time will tell.
