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.....

Energizers are consistently reliable and long lasting batteries. It is good to have extras on hand. Never want to run out!

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

These 9v batteries last longer as expected so you can trust this brand

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

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

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.

Good batteries good value. WHAT you need 50 characters just to say they are good Batteries? Get a Life.

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.

The Energizer - MAX 9V Batteries (2 Pack), 9 Volt Alkaline Batteries are strong and will last a long time. Saves having to replace smoke detector batteries so often.

Great battery- long lasting,reliable product, for smoke and carbon monoxide detector-preferred brand

Great Batteries! I use these primarily for my smoke detectors. I currently cant find them, i was pretty sure i had a few left and this is when i need them and theyre nowhere to be found and im going to look once more then i might buy some more

These batteries work great. I will use them for many items.

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.

Energizer batteries are among the highest quality. I bought them at Best Buy because, using the rewards points I had earned, the price-quality ratio was unbeatable compared to any other store.
