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

    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.

    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!

    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.
