### ⭐⭐⭐⭐⭐ Professionally Made
*by S***Y on July 10, 2025*

I have been using these in the field. My normal go to 9volt batteries tend to last only a few hours with my equipment. These batteries are lasting all day of useage. Very happy them. Pricey comparing to most batteries, but being lithium, a good value.

### ⭐⭐⭐⭐⭐ Seems decent, using in smoke detectors for multi-year use before changing...brand is good
*by N***R on July 14, 2025*

These seem okay, no duds so far. They are lithium and using in smoke detectors to prevent annual battery changes. If they get low, I'll get the dreaded low battery beep. This way I am not trying to change these every year. So far, so good, but it's early. past experience with this brand has been good.
