Customer Ratings & Reviews

I wanted to see if my 30+ year old swatch watches would still work. Best Buy had the batteries that I needed at the best price. Happy to say that they started right up and have been running great.

I got this for my watch and it works great. The price is good too.

What more can be said about Energizer’s battery? They’ll get your device working and sport a battery life that’s industry leading.

Good battery. Hard to find, but Best Buy had it in stock.

Had an old dead calculator containing a button cell battery that only had "G10-A" engraved on top. Upon Googling, that's a different name for the same cell as this 389/390. Now the old electronic abacus is back in business.

I like that I can find any battery size I need. Thank you.

Cheap foreign original battery did not last long, and this was only battery Best Buy had, so I bought two, and the thermometer/clock/calendar is working fine. I have used Energizers in the past for other electronics and they have always provided good service.

This was exactly the product I needed for my lighted magnifying glass and I couldn't find this anywhere else!

Batteries! Who doesn't need batteries! Energizer batteries are good!

Great fit for my watch.Easy to install. I would recommend.

This size battery was hard to find at a reasonable price. Best Buy had it in stock and at the best price around.

picked this up for my hygrometer and these little batteries do last a long time for me. Definitely check them out and see how they work for you. My use doesn't use too much power so they last me a good time.

Fits perfectly and the price was just as appealing.

These batteries have been hard for me to find. Bought these online from Best Buy. Delivered free, quickly and on time. Very happy with the Best Buy online ordering experience.

It’s a battery, and it works! The number on this battery replaces an older version so always crosscheck the numbers if you can’t find the one you need... it may be renumbered.

After buying batteries at discount stores, claiming to be compatible, that were just WRONG! I ended up online Best Buy finding exact fit battery available in just a couple days. Worked great exactly as needed.

Christmas just isn't the same, when your favorite ornaments don't perform because their batteries have died out. Best Buy had the right size batteries at a much better price than the neighborhood pharmacy.

Their batteries and work well, what else to say???

I had to get 3 of these for a jewelry loop and their good batteries, I only used the loop once, so they're good for that time.

I purchased this battery to replace the battery in my cigar humidor and so far it's performing to my expectations. Satisfied
