Customer Ratings & Reviews

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.

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

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.

This nine-volt battery appears to be working okay. It was simple, quick, and easy to install and connect. I would have preferred to purchase a single battery, but I understood only a two-pack was available.

gets the job done, very reliable and you get a reputable brand

Energizer batteries always seem to work good. We usually use this brand.

Great battery. Would buy again. And again and again and again.

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.

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.

This is the long lasting battery I brought for my lockbox. Can’t go wrong with this excellent battery.

They are batteries, what more can be said? Well, Best But actually has some good prices on batteries at times. When you get those surprise $10 coupons in your email...you just may need some batteries!

Works great. Just like expected. I got what I paid for

These are the only batteries for our smoke alarm. Very important place to have dependable batteries. I hope they never go off, but I want to know they will if needed.
