Duracell Coppertop 9V Battery, Long Lasting Batteries, 4 Pack

I'm in my last few batteries but these lasted me a good four years. We use these for certain electronics and these last really long. One machine I use them for is a electric muscle massager which uses a lot of power and it's 60 minutes per session. One battery lasts me weeks with continuous use so that means their capacity is really high and they drain slowly. They also offer a guarantee that if you're not satisfied with the product you can call the number in the back and I assume they'll give you replacements. Although these packs can be expensive, it's one of those purchases you buy one time and you're set for years.

my combo smoke and CO2 detector went through battery faster than one yearly replacement. so battery life is not good enough. it not simply this brand or that. it's a real issue for smoke fire CO2 detector to use battery faster than industry recommend|nds battery change out.

These batteries last a long time in our smoke detector. You can get a value pack for all our smoke detectors in our house. I trust no other brand! ..

Fantastic batteries at a great price. These Duracell batteries offer top class performance whatever you use them for. The batteries last a very long time and will enhance your products. They can be used for a wide range of products.

I've used Duracell batteries for years and they are my go to for all of my battery needs they last a long time and have higher reliability than off brands.

I use this battery in Several Items around the house mainly the smoke and carbon detector. It is reliable, and lasts longer in storage. I recommend Walmart's delivery service to many of my friends and family.

Love Duracell batteries!!! But way too expensive!!!

One of the 4 battery bought for my 4 Smoke Detectors was praticly dead. (Indicated Replace on my battery tester) Would not recommand

Walmart needs to fix it's website!!! Not in store so we can ship for free but, we can't ship to you BUT every time I select the 'SHIP' button, it says it can't ship to my address that other items in my order are ALREADY SHIPPING to!!!! Walmart - get some USA programmers on it!!! And WHY would I add my height and weight to a review??? You need to remove that!!!

I did not receive the correct batteries
