Last long and does the job ! Used it for my alarm system have yet to replace it but no need so far and had it for months

We've all seen the bunny commercials, touting Energizer's longest lasting batteries. Hyperbole aside, they are some of the best batteries on the market for life span. You do pay a bit more than other brands (except the "Copper Tops") but you get more time without having to change them out. The downside is that you can purchase nearly twice the Rayovac or Amazon brand batteries for the same price.

Battery works well. It last longer than the dollar store brands.

Good value for a package of standard batteries. They last as long as any other name brand

I got these batteries because it was that time of the year to check the fire alarms/ Carbon monoxide detectors and I never buy the cheap batteries when it comes to me and my pet, I like Enegizer batteries they last long and because I was at Best Buy buying something else I pick these up.

The perfect price for a long lasting battery. I need it for my smoke detector and It lasts a long time.

Batteries were what I needed and what I eventually got. Unfortunately, although I ordered them for 1 hour pickup, when I got to the storem they weren't available. 3 days later after another trip to the store, I finally got what I needed. It's a weird system--- they told me at the store that I'd have to cancel my own order, and since I'd used a rewards certificate to buy the batteries, it wasn't possible to get my rewards back in my account immediately (so I couldn't just walk over to the battery section and get something off the shelf). Pickup was unfortunate as well- I had to wait on the normal checkout line (which was also handling returns) to get my online order. A lot of opportunities for improvement! First, know your inventory and don't say something is available for 1 hour pickup if it isn't. Second, have someone occasionally see if anyone is just picking up an online order so those folks don't have to wait an inordinate amount of time as everyone checks out for something that's already paid for and should be a quick pick-up. Third, empower the store employees to cancel and online order rather than telling the customer to do it him/herself; if the order was using rewards, then immediately credit the rewards back into the account so they can be used on something in-store since you're already there to pick up the item that should be available and isn't. I hope some of these ideas are helpful!

The batteries are durable and long lasting. The batteries are priced good.

These always make an excellent gift for someone on your Christmas list!

Best Buy has great prices on all their batteries. Would highly recommend shopping there.

Good purchase. No problems at all. Pick up with no hassle.

Always reliable. Long lasting. Good price. Would buy again.

Our 2 new smoke/carbon monoxide detectors require 9V batteries and were not something we normally have around. I was pleased to see the Energizer 2 pack for such a reasonable price for such a dependable brand.

These are the only batteries that have never failed me. I use several types of wireless audio systems and digital equipment that are all battery operated and Energizer batteries always work better than every other battery I have tried. I have tried several other brands, which do not perform nearly as well a Energizers. Energizers seem to last so much longer.

Great. They worked out great. Good purchase. Used them for fire detectors

This little pink bunny is a work horse and I love these batteries. When you compare the cost of these named to no named it's a no brainer. I must say though that Duracell is a real close 2nd!!!

The Energizer batteries are good and durable. They last longer than many others I’ve tried and always deliver consistent performance

I was so glad to find this two package of Energizer 9V2 batteries at Best Buy. I needed them to use at my home. I have used Energizer batteries in the past and have been very pleased.

These things last forever. I use it for the smoke alarm and I change them once a year. They still have life in them but just to play it safe I always change them once a year. It's always best to do that because if you wait for the device to beep maybe you say I'll do it tomorrow or you procrastinate with other excuses. I like to do it the way I've been doing it.

Great Price for replacement batteries for smoke detectors in the house. Always need to keep some on hand for those midnight wakeup beeps!
