I am getting frustrated because I change the batteries in my alarm clock at least three times a month. I don’t know how much I’ve spent just on batteries alone. I don’t even want to think about it. I want to be able to find batteries that really last long. A friend of mine told me that maybe I should try saft lithium batteries, which may be used for electronics and other battery-operated gadgets. She said these batteries last about 3-20 years, and this made me want to try the batteries out even more. I just need to ask my friend where she buys her stash so I can buy several, too.
