Great battery needs to have a few of them great job

You had the right replacement batteries for the battery that I was looking for. As I had looked everywhere for the battery and no one had them.

Always very reliable brand. Easy to install. Lasts long.

Good battery for unique camera for daughter. Works great

Battery works great knock off was fully charged sealed authentic works great even months later

I needed replacement batteries for my calculators and was looking for a silver oxide 389 button battery which has a much longer life than the alkaline type. I needed only two batteries and Best Buy had the Energizer 389 button batteries in stock. The price was comparable with Amazon and there was no shipping fee with free store pickup. The batteries are working fine.

This size of battery is very difficult to find. I was very happy to find them at Best Buy. I went to several stores looking for this size and no one had them. Best Buy also sells them for a very reasonable price! Thank you Best Buy for stocking every battery that I need to run my home!

My wife loves math, but her calculator doesn't. It stopped working one day and left her in a lurch. We needed a new battery, but they cost an arm and a leg at the stores. Luckily, we found this one online and we got it in no time. The battery fit like a glove and gave new life to the calculator. It has been working like a charm for several months now. A great product! And here's a joke for you: Why did the calculator cross the road? Because it wanted to be on the other sine.

great battery that i needed to replace. very quick shipping

This battery is pretty powerful, i have used it for indoor lighting and it works great, i recommend this product.

Better price and quality, I recommend it to any one.

I had an 80's themed event where you were expected to come in full period dress. I wanted to see if my old Swatch Watches would still work after sitting dead for 30 years. Sure enough, as soon as I put these batteries in, they started to tick. I just checked them and they are still running fine nearly two years later...well with the exception of the second hand on one that seems to not move with the ticks, but still keeps time. Glad these worked and allowed me to wear two Swatches on one arm like we did in the 80's.

I don't remember buying this. I am guessing I had money left over on a best buy gift card and bought it to utilize the rest of the money.

Great battery. Perfect fit and no issues. It fit right in my device and seem to provide good power.

Needed a battery for my watch, got it at a great price. Watch is still ticking and should last awhile.

Easy to install and confirmation for compatibility

my 15 year old $3.00 calculator was not working right so I opened it and took the battery out, figured I give it a try before I threw the device away. The battery number, I believe is obsolete, but after a few minutes of research I found that this is the battery that replaces that old number. Worked good. My calculator is working as if it was new.

I searched so long to find these specific little batteries for my thermometer. It was also helpful that Best Buy has a display explaining which tiny specialty batteries are compatible with each other.

inexpensive alarm clock battery. compatible with other generic brands.

I am in my 7th decade of life, and without a doubt, this is one of the greatest batteries I have ever purchased. The battery was very easy to purchase online and pick up at the store. It was also very easy to install in the calculator. It has worked flawlessly for a month now and I hope it will continue to work for a long time.
