Customer Ratings & Reviews

I ways use Energizer batteries, they last long and are affordable. The Energizer power banks also can hold a lot of power enough to power two devices simultaneously.

It’s the right price, the right amount of batteries needed for the right project! It’s that time of year when we need to check our smoke detectors and replace the batteries for our family’s safety.

Energizers cost a bit more than others, but in my experience are definitely superior. I use these for microphone transmitter and receiver at seminars. The systems goes through batteries very quickly, and lesser batteries only last 4-5 hrs max. The Energizers lasted over 8 hours and still had juice.

This battery hit the nail on the head as far as what i was hoping for . 100 percent perfect fit for my range finder and has yet to skip or miss a step like the rabbit says ...going and going and doing.....

Battery in my safe went out again. So I solved it with these longer lasting batteries.

Best Buy is my “Go To” for all of my electronic needs. Their team has the products and support to accomplish my technical goals.

It is always a safe bet to go with Energizer brand.

High quality batteries at a fair price. They have succeeded my expectations

Be sure & check the Product/Model Number on this twin pack before check-out. You want 522BP-2E, not 522BP-2. You'll save $1.00. You cannot tell a difference other than this model number, UPN, and bar code on the package (I have them both in front of me). But, if you get the 522BP-2, you'll be charged a higher price. Currently, $9.99, vs. $8.99 for 522BP-2E. Don't make the same mistake I made. I've brought this to BBY's attention and here is their response per one of their CSRs: "52. Vince Sanchez: Both the batteries are the same and both are 9v general purpose batteries. It is the price set by the manufacturer!" I have sent several emails to Energizer and even phoned them with no response.

I bought this for an old stud finder that had died, and it didn't work. I ended up buying a new stud finder, only for the battery still to fail. We did the old-fashioned tongue check and nary a jolt. Judging from the bottom, we wonder if it overheated during storage at some point.

These batteries last a long time in my Smoke Detectors and other such devices. No issues with corrosion! I trust Energizer Max Batteries to give me service.

Good batteries. Perform as expected, no problem, if you need 9 V I would recommend these.

I've had the best performance from Energizer batteries over the years, so they are what I use exclusively unless I can't get them for some reason. And these came at a great price with my Best Buy membership!

I ordered Batteries on line. The process was quite easy. I actually had them delivered to my home and wanted to see how that process was well. They were supposed to be here on a certain day and they were not. It ended up being like maybe four days when it was actually delivered!! I actually ordered something now, but I’m picking it up in the store!

Great Batteries. Strong lasting power. I would disclose what these batteries powered, but my mom reads these.

This little pink bunny is a work horse and I love these batteries. When you compare the cost of these named to no named it's a no brainer. I must say though that Duracell is a real close 2nd!!!

I was so glad to find this two package of Energizer 9V2 batteries at Best Buy. I needed them to use at my home. I have used Energizer batteries in the past and have been very pleased.

The Energizer batteries are good and durable. They last longer than many others I’ve tried and always deliver consistent performance

Works great in my acoustic electric and great value for total tech memvers

Fits where a 9V battery should, snaps onto the terminal snaps perfectly. Provides power as it should and Energizer has proven to have a long shelf life.
