Customer Ratings & Reviews

Good brand,this is the first time I will purchase this brand.

Product works as expected and when needed in smoke detectors.

The battery seems to work for at least 6 months of continuel use. It could work longer but it's a replacement for a smoke detector.

They worked as expected. Other batteries I have purchased have lasted as long as I expected. I expect these to do the same thing.

I purchased these 9 volt energizer to power a carbon monoxide detector, and so far the batteries are working very well.

It's a battery lol. Not much to write about. It will last.

Great batteries. Worth the money. Last longer than all others.

Great battery! Energizer is a great brand and it exceeds my expectations regarding lifespan of the battery

I use this battery in my crybaby wah wah pedal for my live performances and it's good for multiple shows.

That time of year to replace batteries in the smoke detectors. Energizer 9V batteries are always a reliable choice.

Works as advertised. Needed barriers to replace the old ones in our smoke detectors. Not much else to say.

It's a pair of 9v batteries. They fit standard 9v housings. If you need some these will do the trick.

These batteries work well compared to other leading brands and are competitive when comparing prices with coupons available monthly.

great product will for sure recommend to everyone!

Its batteries and they work. Cant say much more about them. Now the computer i ordered and not here yet doesnt make me happy

This was a classic case of you get what you pay for, I needed to replace the battery in my garage door opener and picked up a pack of lowest priced 9V from an un-named store and they died within 2 weeks, picked these up and have been going strong on the 1st one for a month so far.

Works like a charm. Able to power up a metal detector finder whenever necessary.

Excellent. It last longer to use . That' s why I alway only buy this products.

Fast delivery as usual. No issues using the batteries.

Excellent worked extremely good and there was no issues.
