Good battery for the money. I purqchase these to replacce all the batteries in my smoke detectors. They easily last past the every 6 month suggested change time on smoke detectors. I also use this battery in my keyless entry garage side door lock and it last at least 1 year.

9 volt batteries, what can i say, they work, they don't last the longest but they work. I would buy again. Thank youRF*

I'm never quite sure what to write on items that don't need a big description, but essentially these work well, snapped right into my smoke detector, and stopped the annoying beeps. Good value for the money, would purchase again.

Appear to be a good battery. We'll see how long they keep the smoke detectors powered up.

Fabulous rechargeable batteries. They fit perfectly in my husband's home made piano light he made for me with LEDs. The batteries (8 for one serial load in the light) last me between 4 - 6 hours before I need to put a newly charged set of batteries in and charge the ones taken out of the light. It's easy, effective, and oh so rewarding!

I bought these batteries to use as replacements in my smoke detectors, but it proved difficult. The plastic label that surrounds each battery must be thicker than name brand batteries because I struggled to get the battery to fit inside the smoke detector's narrow battery compartment. I had to use a small screwdriver to pry it in place and have never had to do that with other batteries. Better to be used for toys or electronics.
