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

Considering the price of batteries these days, this was a good deal. They were easy to find in the store without having to ask somebody. I have been using them in my tens unit. And it's been over 2 weeks, and i'm still on my first battery

Great for many products in my house that uses batteries.

Good price. Good working batteries for every day storage

These are good batteries . I use these in my fire alarms and they seem to work good for me . I replace them yearly.

Very good. Got a good price. Use for smoke detectors.

Top brand of battery on the market, it lasts twice as long as the other guys.

Just returned these things before opening. My father don't think it's wise to use nice new batteries for a fire alarm.

I use these batteries for my work equipment such as testers or toners and they work perfectly for a long time.

AFFORDABLE MULTIPACK OF NINE VOLT ALKALINE BATTERIES.

Excellent price. Long lasting. As good as more expensive brands

This is a four pack for a pretty good price. Seem to work well in thermometers and smoke detectors.

I mean….they’re batteries. They do battery things in a very battery like way.

Works great, got them to replace the batteries in my smoke detecters.

Batteries work as they should. Still using this set.

Good alkaline batteries for less than cost of Everyready or Duracell. Why pay more?

Not had any issues while using them so far. Would recommend.
