Standard battery at a fair price.It’s too early to give a complete review, but I fixed a thermometer by installing one of the batteries. Time will tell the rest of the story.All the batteries were in a manufacturer package. When they arrived they were in an ordinary envelope....nothing wrong with that however there was nothing that identified who sent it. The batteries work and that's all I really cared about.I installed one and it works but time will tell how long it lasts.I was glad to find replacement batteries on Amazon. I never found these in any stores. They were for a small timer that I use at work. I could have bought a new timer, but that's such a waste. The price was very good too.Purchased in 2022, "use by 2023" on the packaging. Brief research of these alkaline batteries suggests a 5-8 year shelf life. Where did these batteries sit for 4 years before they were sold to me. I previously purchased Energizer LR41 batteries on Amazon and had to throw them away as they were DOA with nearby expiration dates. Are any fresh batteries sold on Amazon?All the batteries in this pack read Lo on 2 different thermometers even though the expiration date was 2028. I wish I had read the other reviews before buying these batteries. This company is a scam!Replacement battery for those digital thermometers you can get at the dollar store. I used to throw them away when the battery died and buy a new one but after Covid, thermometers were not available. I then realized my cheap digital thermometer had a battery inside and once I replaced it they all worked like new! Now I have plenty of batteries to spare! Great find and not so wasteful.Battery works well on my keychain light stick which takes 3 of these L41 batteries. The light is pretty bright, seems brighter than the batteries it originally it came with. I don't have a meter to check the voltage, so can't confirm if the battery are actually good. Will have to see how well it lasts. The package doesn't state the use by date.It works for the fractions of the price you usually pay for branded LR41 (= SR41/192/392/384). I don't know which region these batteries were packed for, but the package's warnings are written in English, German and French.Amazon was the only place I could find these batteries. Worked well for me.Le pile le ho usate per termometri e orologi. Vediamo nel tempo quanto dura la carica.prese per termometro sanitario; nessun problema
