Energizer Zero Mercury Alkaline A23 Batteries (2-Pack) - Long-Lasting Power for Smoke Detectors, Garage Door Openers & Medical Devices

Works just like the ones I bought in the store, but these cost a lot less.Most nights it helps me sleep at least 4-5 hours without waking up.I have Forestier's disease along with Spinal Stenosis.Worked perfectly in my fan remote and it was the cheapest option.My garage door remote failed and identifying the issue, I replaced the old battery with an energizer battery, Worked fine! longevity looking forward to several years.I didn't want to pay for six batteries when I needed only two. At $2.79 for two batteries (AUG2022), this is a reasonable option.Hard to find size battery works well for my ceiling fan. Since it was just installed I gave longevity only one starGood value for the priceBought these for my fan remote. Came in next day. Popped them and I was ready to go.Ordered two packs of these batteries as I believed that being in original energizer packaging might give me a reasonable expiry date. No such luck on 8-10 years. Got them feb7/22 and expiry date is march/23. So will unlikely get full use of them.Obviously the supplying company is supplying near expired batteries at a discount. (Am presuming they’re cheaper). Also being near expiry date they may not last nearly as long. I really think this is fraudulent selling as one does normally expect about 10 years of shelf life. I would not buy batteries again through Amazon. The presumed lower price is not worth getting only 10% of normal expected shelf life. Just tried to use the batteries and none worked . They are 12 V batteries and all tested between 7-9 V, way too low. Supplier was “My battery supplies” via amazon. Don’t waste time with their batteries. I sent them back for refund.Definitely received A23 batteries but was shipped old stock, received in May 2022 and best before date was March 2024. Most batteries when manufactured have 7-10 years. These are long-use batteries for remote controls that you would expect to use for at least 3 years and to receive old stock cuts their useful lifespan. At least when tested they were still 12V.Buena relación calidad precio. Energizer es de muy buena calidad y en este producto tiene un precio mucho menor que las marcas genéricas como Steren. ATENCIÓN!! Esta pila es de 12V pero su tamaño es idéntico a un nuevo tipo de pila que es de sólo 3V. Revisen cuidadosamente qué pila es la que requiere su dispositivo antes de ordenar el producto.These are awesome. I bought them as back ups for my wireless doorbell. Haven't needed these yet. There is no "best before" indication visible on the batteries or the packaging. They haven't exploded in the two weeks they've been sitting in my cupboard along with the rest of my battery spares.I view NOT exploding as a very positive sign, particularly since these were the priciest option for replacements on Amazon.Assuming that these do not explode and my doorbell requires batteries, I'd likely jump at the chance to buy these suitably vaguely marked batteries. Zero Mercury folks.las adquirí para renovar la bateria del control de porton y sin duda mejoro todo estas son una pilas no tan facil de encontrar en tiendas departamentales y pues llego a tiempo fue muy facil de cambiar y ahora funciona muy bien ....es mas abro la puerta desde una cuadra antes de llegar woow
