Customer Ratings & Reviews

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.....

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.

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

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

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

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.

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

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.

Great Batteries! Would buy again! Fit perfectly and when tested were fully charged

I got these batteries because it was that time of the year to check the fire alarms/ Carbon monoxide detectors and I never buy the cheap batteries when it comes to me and my pet, I like Enegizer batteries they last long and because I was at Best Buy buying something else I pick these up.

Batteries were what I needed and what I eventually got. Unfortunately, although I ordered them for 1 hour pickup, when I got to the storem they weren't available. 3 days later after another trip to the store, I finally got what I needed. It's a weird system--- they told me at the store that I'd have to cancel my own order, and since I'd used a rewards certificate to buy the batteries, it wasn't possible to get my rewards back in my account immediately (so I couldn't just walk over to the battery section and get something off the shelf). Pickup was unfortunate as well- I had to wait on the normal checkout line (which was also handling returns) to get my online order. A lot of opportunities for improvement! First, know your inventory and don't say something is available for 1 hour pickup if it isn't. Second, have someone occasionally see if anyone is just picking up an online order so those folks don't have to wait an inordinate amount of time as everyone checks out for something that's already paid for and should be a quick pick-up. Third, empower the store employees to cancel and online order rather than telling the customer to do it him/herself; if the order was using rewards, then immediately credit the rewards back into the account so they can be used on something in-store since you're already there to pick up the item that should be available and isn't. I hope some of these ideas are helpful!

Energizer battles seem to be best them seem to last a long time. No complaints I would recommending them.

We've all seen the bunny commercials, touting Energizer's longest lasting batteries. Hyperbole aside, they are some of the best batteries on the market for life span. You do pay a bit more than other brands (except the "Copper Tops") but you get more time without having to change them out. The downside is that you can purchase nearly twice the Rayovac or Amazon brand batteries for the same price.

Great Price for replacement batteries for smoke detectors in the house. Always need to keep some on hand for those midnight wakeup beeps!

Great 10 volt battery! I use these all the time for smoke alarm. They last a good long time.

The energizer batteries are the only batteries I use they seem to last longer.

These batteries work as intended. I would recommend in the future.

For the price compared to Duracell, it is a good battery. Although, between using Duracell and Energizer over the time I have been buying batteries, Duracell has a longer life span but much more expensive. Never measured time of life vs. money between the two. Good battery overall.
