Customer Ratings & Reviews

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

These 9v batteries last longer as expected so you can trust this 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 - see photos). 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 on my second purchase of this item on Dec 26, 2020. 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.

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

I recently purchased a 4 pack of 9 volt batteries from Best Buy and I couldn't be happier with my purchase! These batteries have been reliable and long-lasting, providing power to my devices without any issues. The convenience of having a 4 pack ensures that I always have a spare when needed. Best Buy's quality and service continue to impress me, earning this product a solid 5 stars. Highly recommend for anyone in need of reliable power!

Great batteries for a great price.....They are the best ones as compared to others.

For those devices that you use all the time, these batteries last longer than the other brands. Great quality and very dependable!

Energizer batteries seem to last longer. Competitive prices.

Energizer is a good brand. THe 9V battery is very common for smoke detector. Easy to install and the battery life is good. Highly recommend to other people.

What can I say….always buy these for my hard to reach areas because they last.

MAX 9V Batteries (4-Pack) is the best product for this price gives good result for fire alarms i used all the time with best result .

These are really good batteries. They last a long time, have a long shelf life, and don't leak like the Duracell brand does.

Good batteries. They last a long time. Bought them at good price, it was a deal of the day.

It’s great to buy the value pal to keep a few batteries on hand, rather than waiting for a battery to die and then go out to buy a replacement. These batteries have a really long life, reasonably priced.

face it, with batteries you get what you pay for. The brand names are better, the max definitely lasts longer. Go for it!

Prices were lower than other places this batteries seem to last forever.
