Customer Ratings & Reviews

I bought a 4 pack of these Rayovac 9 volt batteries and am using them in my DMM and smoke detectors. I use the DMM for 2 ~ 3 hours per day and this battery is still working after > 2 weeks (even with the back light on a lot of the time). It fits well in my smoke detector where other makes of batteries were a tight fit.

Good batteries, used in smoke detectors and garage door key pad.

Probably the best brand of batteries for the price.

Great products last longer then expected. Did exactly what it was supposed to do

High energy as claimed, hope it lasts longer so my smoke alarm won't go off due to low battery
