The batteries are very long lasting and I love them. Great price.

For the most part, I've been pretty bias to the brand but for god reason. It lasts a long time.

I use these batteries for the smoke detectors in my house. They seem to have a long battery life.

Great and dependable batteries. Purchase them over and over again.

This battery works as expected. Long lasting batteries

It's a battery. It does the job for what you need and that's about it.

Great batteries from Energizer! Use for the smoke detector!

Time to replace the fire alarm batteries. Keep the house safe. Went with a known brand. Good quality.

great batteries for smoke detectors which you should change yearly for safety

Reasonable price for 9 v battery. Replaces battery in smoke detector and leaves one for future use.

These batteries are juiced up. They can stay in the package for a year and still power up great.

These are great batteries. Great capacity, Never leak. Don't hesitate to buy them.

Excellent product. Multipurpose Long lasting batteries

I bought these to use in my smoke alarms. I think they will last a long time.

The poor rating is not for the Energizer brand but for the delivery. The package was delivered on a really cold below zero day. The delivery service never rang my doorbell and I was home all day. I looked at my email hours later and it said it had been delivered so I looked for it. It had blown off the porch stoop. It was in a very small packing envelope, just slightly larger than the battery packaging. When I found the package I thawed the batteries out in the house. One of the two 9V cell cases appears to be slightly swollen. I measured the voltage across the terminals and it is not useable. The other cell is measuring a good cell voltage but there is no way to determine what it's long term reliability will be. I guess this is the chance you take when ordering something in the winter. I'm assuming the sub-zero temperature caused the damage in the one battery. In the past I've always had great success with Energizer batteries.

These are good batteries, made better with BB certificates.

Just batteries, nothing spectacular to see here. They last long on my son's remote control truck
