Its long lasting and durable. I recommend this product .

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.

product looks good, delivered on time, will consider to buy them again

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!

great battery peace of mind knowing we will not have to change it often

Very good batteries. They are long lasting and I have never experienced any leaking.

Used on my rode vid mic pro at an event. Works like a charm.

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.

Works great I love how long it lasts for lights and stuff.

Energizer batteries never let me down! I rely on them for so many different things in our home!

What can I say? This is the best brand of batteries on the market.

This nine-volt battery appears to be working okay. It was simple, quick, and easy to install and connect. I would have preferred to purchase a single battery, but I understood only a two-pack was available.

So glad I found this battery at best buy for my smoke detector. Worked great. I went to other stores and it was out of stock. Best buy is good at replenishing their items.

Use to purchase only Duracell. Found out Duracell was owned by P&G. Won’t bring any P&G products into my household so I gave Energizer a try. Great batteries. Long lasting in all my devices – mice, remotes, etc.

Worked perfectly in my smoke detector. Also used it in my speaker

Use these in my guitar with active hambuckers. Last forever.

This is the long lasting battery I brought for my lockbox. Can’t go wrong with this excellent battery.

These batteries are exactly what you’d expect from Energizer- energized! They’ve done exactly what I needed them to do... no surprises there.
