That time of year to replace the battery in smoke detectors, great option

Hands down the most decent batteries I've ever owned

they are what they are. Don’t break your head and just buy them if you need them.

We bought these at an excellent price and have been very happy with them. I will buy more.

I love the qualities of these batteries.... They are long lasting !!!!

They are batteries, what more can be said? Well, Best But actually has some good prices on batteries at times. When you get those surprise $10 coupons in your email...you just may need some batteries!

Energizer are among the best batteries.They are reliable and last a long time without US. I always find that when I have Energizer batteries it is a good result definitely recommended

It's hard to rate this purchase. Presumably the batteries are high quality and will have an extended shelf life and all that. I was simply stocking up and that's a good idea, I think.

Love energizer batteries! Never had an issue with them

The long life of these batteries is great peace of mind that my electronic locks will go a long time before needing the next battery replacement.

Best Buy seems to be getting out of the battery business. There is very limited choice of products. If you think you will have a continuing need for them, consider stocking up now. Buying a multi-battery package also brings down the cost per battery considerably.

The energizer MAX 9V Batteries, 9 Volt Alkaline Batteries is very good and last long time. It is the only brand that I use.

Excellent product. We've been using them for years for our smoke detectors. Change them out once a year because they last a long time.

These are the only batteries for our smoke alarm. Very important place to have dependable batteries. I hope they never go off, but I want to know they will if needed.

I have always used these for my smoke detectors. I sate them when I replace them. Every 6 months is my term. I found one that was a year old and still working

It was that time of year again when one's battery operated fire alarms need changing and this package was the perfect fit. The price was the best around as well.

Used my $5.00 Best Buy Rewards points for this purchase. Needed to replace the smoke alarm battery. Long lasting battery makes it ideal for a smoke alarm battery change!

I have an electronic door lock on my front door, it is a bit of a pain in the butt to change that battery so I prefer to not have to do it very often! These last a long time, which I appreciate.

Yes, 9 V Energizer batteries on sale! Only Best Buy can rock out a super sale and include Energizer batteries. The finest four pack of 9 V batteries I’ve ever purchased. Thank you

these batteries are really good for the price of them!
