Love energizer batteries! Never had an issue with them

That time of year to replace the battery in smoke detectors, great option

I always buy these batteries for their long life. The bunny keeps going and going,

Did quite a bit of research as I was not wanting to constantly replace this battery. It had done an exceptional job at keeping its charge!

I don’t know what else to say about batteries besides the fact that energizer is always the way to go when it comes to batteries lol keeps a long charge

I love the qualities of these batteries.... They are long lasting !!!!

I was recently on a trip and needed a battery for a tens unit due to the rechargeable one quit taking a charge. I saw a best buy and bought these to replace the dead ones. They worked great and kept a strong charge.

What can I say? Tried and true over the years. Pro-tip: Do not lick.

always trust the name anergizer to power your most trusted devices. a little more $ then the cheapos but months more of energy.

I mean… they’re batteries. Good ones. I buy these for my preamp on my acoustic guitar and active basses. They last a long time.

Although I don't use many 9-volt batteries, I need one every now and then. I always buy Energizer. Can't miss with this brand. Definitely the "go to" selection when it comes to batteries.

Works great I love how long it lasts for lights and stuff.

Used on my rode vid mic pro at an event. Works like a charm.

great battery peace of mind knowing we will not have to change it often

Very good batteries. They are long lasting and I have never experienced any leaking.

The long life of these batteries is great peace of mind that my electronic locks will go a long time before needing the next battery replacement.

The energizer MAX 9V Batteries, 9 Volt Alkaline Batteries is very good and last long time. It is the only brand that I use.

What can I say? This is the best brand of batteries on the market.

This 9V battery comes as a twin pack. I needed to replace the battery in our smoke detector every year and it uses only 9V batteries. Since these come in twin packs and the newer version can retain their power for 5 years (in storage), this will save me a trip to the store next year and not have a lapse in the detector's operation. Power retention is key for my purchase.

It's hard to rate this purchase. Presumably the batteries are high quality and will have an extended shelf life and all that. I was simply stocking up and that's a good idea, I think.
