The battery last a long time. Thank you.I prefer lithium AAA batteries, but they're expensive. For noncritical, indoor devices, I use traditional alkaline batteries. My search for low cost, brand name, AAA alkaline batteries found these.The pros:+ Low cost of $9.96 for 24 AAA alkaline batteries with free shipping.+ I always do a voltage test (without a load) on all batteries I purchase. All 24 batteries measured around 1.60 volts.+ Expiration date of 12-2026.+ Advertised - economical power for modern devices that demand high power and are heavily used.+ Advertised - 24 per pack.+ Advertised - material: alkaline manganese dioxide-zinc.+ Advertised - not rechargeable.+ Labeled - made in USA on the box. ◄ For those that like to buy products made in the USA.The cons:- None so far, but I'll update this review if I discover one.Closing comment:▪ The 24 batteries come packaged 4 batteries per box. The 6 boxes, containing 4 batteries each, are packed within a larger cardboard box.▪ I generally don't like alkaline batteries, as they will leak if they're left installed after they're depleted... dead. Depleted batteries need to be removed quickly, or they can leak & cause damage!Can’t go wrong with Energizersgood batteriesJust installed them. Have to see about durabilabity and longevityI'm still testing so I need to see the durabilityI took these batteries out of a smoke detector that was installed over 5 years ago. These batteries were purchased to replace the ones removed. I'm hoping the batteries purchased will last just as longThis purchase wound up being a necessity for me. The wireless Fire Alarm we have would ONLY run on these specific batteries, no other Energizer would work since I tried and all our alarm system would do is send out an annoying notification alarm that the batteries were low. Once these arrived and I installed them, NO MORE notifications!Je n'aime pas du tout ces piles ... ce sont les pires que j'ai achetées ... elles ne durent pas plus d'une semaine, comparées à bien celle que j'avais l'habitude d'utiliser avant ... mais vu que c'était écrit INDUSTRIELLE je croyais qu'elles seraient meilleures ... je retourne avec mon ancienne marque ... désolée !!!Use for remotes, battery candles, kids toys. Always keep some on hand because they are long lasting so less frequent changing, and very reliable. I’m a die hard energizer fan!
